Women Serial Killers: Rare Offenders, Common Victims

Serial killers are overwhelmingly male. Victims, however? Mostly not. Across multiple datasets and criminological studies, women show up in a strange, brutal double role:

• They are rarely the serial killers.
• They are frequently the victims of serial killers.

That imbalance is not an accident. It sits at the intersection of gendered violence, misogyny, victim vulnerability, and stereotypes about what “danger” looks like. This article dives into the statistics, the patterns, and the uncomfortable reality: Being a woman doesn’t make someone more interesting to serial killers. It makes them easier to target, dismiss, and erase.

1. Women Serial Killers: Who Kills, Who Dies

Let’s start with the uncomfortable math. Across modern serial killer research:

• The vast majority of serial killers are men. Estimates usually put this well above 80–90%[1]. In the U.S., the FBI has estimated that only about 8% of known serial murderers are female as of 2023[2]. Other analyses that look historically or globally suggest women might make up around 10–15% of serial killers[1]. One criminologist noted that women actually account for roughly one in six serial homicides (~17%) in the U.S., which is higher than their share of overall murders (~10%)[3]. In short: male offenders outnumber female offenders by a large margin.
• Women are heavily overrepresented as victims, especially in sexual or predatory serial killings. FBI data show that from 1985 to 2010, 70% of known serial killer victims were female[4]. By contrast, in ordinary (non-serial) homicides only about 22% of victims are female[4]. That means a victim in a serial murder incident is 3.5 times more likely to be female than a victim in a single-homicide incident[4].

This doesn’t mean “men kill, women die” is a law of nature. Men do kill men, and women do kill. But serial murder in the cultural sense we usually think of it—multiple victims, cooling-off periods, predatory behavior—is heavily skewed: the most “iconic” configuration is a male offender and a female victim. Many of the most notorious cases (Bundy, Ridgeway, etc.) followed that pattern, and the media has reinforced it[5][4]. That says a lot more about social dynamics than about biology.

Why is it so skewed? Largely because the kind of serial murder that gets the most attention (sexual, sadistic, power-driven predation) is deeply gendered. As we’ll explore, male serial killers often choose victims they perceive as easier to overpower or less likely to be missed, which often means women. Meanwhile, the relatively few female serial killers tend to commit their crimes in different contexts that don’t fit the popular “stalker in the shadows” image.

2. Why So Few Female Serial Killers?

Women do commit serial murder. They just tend to go about it in different ways. Several factors contribute to their smaller numbers in the classic “serial killer” category:

1. Socialization and aggression: From early on, boys and girls are socialized differently in most cultures. Boys are more often encouraged—or at least tolerated—in overt aggression and physical dominance, whereas girls are often steered toward more indirect or relational aggression (social manipulation, poisoning, etc.). This doesn’t magically create killers, but it can shape how violent impulses are expressed. As former FBI profiler Jana Monroe explains,

“Men tend to express aggression outwardly, while women are more likely to internalize aggression, leading to self-harm, depression, or relational manipulation rather than physical violence.”.

In other words, a man with antisocial tendencies might lash out openly, while a woman with the same tendencies might act more covertly. This difference in expression means male serial killers more often choose direct, forceful methods (strangulation, stabbing, etc.), whereas female serial killers, when they exist, often choose quieter methods like poisoning[7].

Biology may play a role as well. Monroe notes that hormones associated with aggression and risk-taking (testosterone) are higher in men, while hormones that can promote bonding and empathy (estrogen, oxytocin) tend to be higher in women[6]. Those biological factors, combined with social conditioning, act as a kind of protective buffer against extreme violence in most women. The result: far fewer women than men develop into predatory killers.

2. Access and opportunity: Men and women occupy different spaces and roles at times, which can affect how a would-be serial killer finds victims. Male serial killers are more likely to engage in public predation: cruising streets, stalking strangers, picking up victims at bars or colleges, working jobs that let them travel or troll for targets (long-haul trucking, military, law enforcement, etc.). Female serial killers, by contrast, are more heavily represented in caregiving and domestic roles – nursing, elder care, child care, running boarding houses, etc.[8].

When women kill serially, it’s often through means available in those environments: administering poison or lethal doses of medicine, suffocation or neglect of those in their care, or staging “accidents” at home. They operate in spaces society trusts them to be harmless. As one crime historian put it,

“We are slow to recognize the prevalence of female serial killers because we’re still saddled with societal tropes that females are passive, nurturing figures – not predators”[9].

This means female serial killers can fly under the radar more easily. They don’t fit the “shadowy stranger” model, and their crimes (quietly killing patients or relatives) often look like natural deaths at first glance[10]. A woman who murders several husbands over years by poisoning might raise less immediate suspicion than a man who murders several random women by blunt force. Similarly, a nurse who quietly kills vulnerable patients can hide behind the assumption that people just die in hospitals[10]. Access to victims and the appearance of normalcy allow female offenders to operate differently – and sometimes to avoid detection longer – than a male serial killer who leaves bloody crime scenes in public.

3. Differences in motive: The “classic” serial killer narrative centers on sexual sadism and dominance. Indeed, many male serial killers are driven by sexual urges, lust, or a thrill for power and control[11]. In one FBI analysis, about 50% of male serial killers had a primarily sexual motive (usually intertwined with other motives like sadism or thrill-seeking)[11]. In contrast, female serial killers’ motives skew more toward practical or non-sexual goals.

Studies find that female offenders are most often motivated by financial gain, revenge, or so-called “mercy” (e.g. a delusional belief they are relieving suffering)[12][13]. Harrison et al. found the most common motive for female serial killers was “financial and power gain,” and noted a recent rise in revenge-motivated cases among women[13].

Male serial killers frequently seek the rush of domination – the sadistic pleasure, the sexual gratification, the game of hunting. Female serial killers, when they exist, are more likely to be what profilers call “instrumental” killers: they murder as a means to an end. For example, a woman might quietly kill her elderly patients because she wants the thrill of playing God or the attention of being the hero (so-called “angel of death”), or she might kill relatives for insurance money. These motives are deadly, but they’re usually not about sexual lust. As Monroe observes,

“Male serial killers are often driven by sexual or domination-based fantasies, whereas female killers tend to kill for practical reasons: financial gain, revenge or perceived mercy.”[12].

There are exceptions on both sides (some male killers are profit-driven, some female killers have sexual sadism), but those are the general patterns.

4. How the system labels them (or misses them): There’s also a historical bias in identifying serial killers. Law enforcement was long fixated on a male model of serial murder. In fact, the FBI didn’t even formally recognize the existence of female serial killers until the 1990s[2]. As late as 1998, one FBI profiler publicly claimed “they [female serial killers] didn’t exist at all.”[2] This bias means some patterns of female violence were overlooked or misclassified. A behavior that would immediately be seen as “serial homicide” if done by a man might be written off when done by a woman.

For example, if a male hospital worker mysteriously “lost” a dozen patients on his shifts, investigators might quicker suspect foul play, whereas a female nurse in the same scenario might initially be seen as having bad luck or being overworked. Female suspects often benefit (initially) from gender stereotypes: people find it harder to imagine women as calculated killers[14][15].

This has real consequences. A woman who poisons multiple family members over time might be euphemistically dubbed a “black widow” or thought mentally ill rather than being treated as a cold-blooded serial murderer. A nurse who secretly kills patients may be called an “angel of mercy gone wrong,” framing it as a tragic stress-induced breakdown instead of intentional homicide.

Female serial killers have historically been under-identified or given the benefit of the doubt. As criminologist Enzo Yaksic notes,

“Female serial murderers have been ignored by researchers, discounted as being too weak and fragile to commit multiple killings. But many have been able to hide behind the attributes of trustworthiness and kindness ascribed to them to become efficient and methodical killers.”[15].

In short, societal bias can blind us to female killers until they’ve racked up a shocking body count.

3. Typologies of Female Serial Killers

Female serial killers don’t fit the same mold as Dahmer, Bundy, or BTK. They cluster into different patterns. Experts have identified several common typologies for female serial murderers[16]:

• Black Widows: These are women who kill intimate partners or family members serially, often for financial gain or personal benefit. A “black widow” typically murders multiple husbands, lovers, or relatives over a period of years, usually by less detectable means such as poison or staged accidents. The classic motive is profit (insurance payouts, inheritance) or freedom from a relationship. Black widows are often outwardly charming and appear to be grieving spouses, which helps deflect suspicion. They exploit the expectation that women are nurturing and couldn’t possibly be intentionally killing their kin. (The nickname comes from the spider that eats its mate.) In pop culture, the idea of the black widow is well known – for example, the dark comedy film Arsenic and Old Lace featured two elderly sisters who poison gentlemen callers as a twisted act of “charity.” Fiction aside, real-life cases abound: women like Belle Gunness (who killed suitors and even children for insurance money in the early 1900s) are prototypical black widows.
• Angels of Death (Caregiver Killers): These are medical or caregiving professionals who murder people under their care – patients, nursing home residents, disabled dependents, etc. They often kill in institutional settings (hospitals, care homes) and may do so under the guise of compassion. Methods usually involve medication overdoses, injections of insulin or air, suffocation, or inducing medical crises. Their motives vary: some claim “mercy killing,” others seem to enjoy the power and attention of being at the center of life-and-death emergencies. Notably, a recent analysis found about 39–40% of female serial killers worked in health-related caregiving positions[17][18]. These women are able to kill repeatedly because patients in critical care can die without raising alarm – multiple deaths don’t immediately suggest murder. Cases in this category often only come to light when a suspicious pattern is finally noticed (e.g. far higher death rates on a particular nurse’s shifts[10]). Infamous “angels of death” include Genene Jones (a pediatric nurse who killed infants) and more recently Lucy Letby, a British neonatal nurse convicted in 2023 of murdering seven babies under her care by injecting air and insulin into their tiny bodies[19]. These perpetrators subvert the trusted healer role into a cover for calculated killings.
• Profit-Driven Killers (Comfort Killers): These overlap somewhat with black widows but can extend beyond family targets. These are women who kill for material gain – money, property, or financial security. They might take in boarders, spouses, or dependents and then murder them to collect insurance, pensions, or even steal identities. Their methods are usually covert (poison, overdose, smothering) and victims often include those who trusted them financially. A classic example is Dorothea Puente, a landlady in California who murdered elderly tenants in the 1980s and stole their social security checks. Such cases show a cold, calculated pattern of eliminating people purely as a means to an economic end. Many female serial killers are involved in theft or fraud before escalating to murder, indicating their interest in material gain[20]. In fact, studies confirm the majority of female serial killers’ primary motive is money or profit[20] – hence the term “comfort killers” (they kill to maintain a comfortable lifestyle).
• Team or Couple Killers: Women also appear as partners or accomplices in serial killing teams, often alongside a dominant male partner (though sometimes two women act together). In these scenarios, the power dynamics can vary. In some infamous killer couples (like Ian Brady and Myra Hindley, or Paul Bernardo and Karla Homolka), the male is the clear ringleader and the female accomplice claims to have been coerced or drawn in by love. In other cases, a female may be an equal or even the driving force. What’s consistent is that two people jointly plan and execute murders. Female team killers have been known to participate in heinous acts including sexual torture and sadistic violence, especially when paired with another killer who encourages or validates their behavior[21][22]. Criminologists note that in most killer duos, one partner is the dominant, manipulative figure and the other is more submissive[23]. That dynamic often influences how the criminal justice system views them (the “follower” sometimes gets a lighter sentence by claiming they were under the spell of the mastermind[24]). Yet it’s important to recognize that some women in these partnerships have shown extreme cruelty in their own right. For instance, in the 1980s, Gwendolyn Graham and Cathy Wood were a female-female team of nursing home killers who smothered elderly patients together as part of a bizarre mutual pact – hardly passive victims of a male controller. As psychologist Katherine Ramsland writes, “Women who kill [with a partner] have certainly been predatory, cruel, and brutal. A few have even been sexually compulsive, especially in partnerships with other women. Most of these teams involved a dominant person with a scheming mind and a weaker person who complies.”[24].
• Sexual Predators (“Female Ted Bundys”): This is the rarest type of female serial killer – women who kill in a manner similar to the stereotypical male serial killer, i.e. stranger victims, sexual or sadistic motives, and often hands-on violence. Criminologists Michael & C.L. Kelleher labeled this category the female sexual predator, noting it is exceedingly uncommon[16]. These women act alone, target strangers (often other women or men outside their family), and derive personal thrill or gratification from the act of murder itself. Because they defy expectations of “female” behavior, cases like these attract enormous media attention. Aileen Wuornos (who we will discuss shortly) is a frequently cited example, as are historically figures like Elizabeth Bathory. Modern cases are very scarce, but there have been a few (e.g. a British woman named Joanna Dennehy in 2013 randomly stabbed and killed men for kicks). When such a case arises, the press often dubs the perpetrator with dramatic titles like “Female Serial Killer X” and treats her as an anomaly or monster. Indeed, law enforcement long thought no women could be sexual serial murderers – a belief now disproven, but still a testament to how this type upends gender assumptions[2].

It’s worth noting that these categories can overlap or evolve. A single offender might fit multiple typologies over her criminal career (for instance, a woman could start as a profit-driven killer and later become labeled a black widow after multiple spouses die). But the key point is: female serial killers as a group look different from the male archetype. They are more likely to kill people they know, use covert methods, and have motives tied to money, caregiving, or warped emotional needs, rather than the “lust-murder” scenario we often imagine[25][7].

4. Why So Many Female Victims?

If women are a minority of offenders, why are they such a majority of victims in serial murder cases? The answer lies in risk, which sits at the intersection of opportunity and devaluation. Serial predators choose victims who both satisfy their desires and present the lowest risk of interfering with the crime or causing the killer to be caught. Unfortunately, in many societies, certain groups of women fulfill that deadly equation. Here’s why female victims are so prevalent:

Physical vulnerability and perceived ease: Many male serial killers prefer victims they believe they can overpower or control relatively easily. Women are often targeted because, on average, they are smaller or physically less able to resist a male attacker. Beyond just gender, offenders seek out any vulnerability: they target those who are young, inexperienced, intoxicated, isolated, or otherwise at a disadvantage. In practical terms, a predator finds it “easier” to abduct or subdue a lone woman than a man of equal size. As serial killer Gary Ridgway (the Green River Killer) chillingly put it, he specifically preyed on prostitutes because

“they were easy to pick up…and I thought I could kill as many of them as I wanted without getting caught”[26][27]. He later told investigators, “I thought I was doing you guys [society] a favor, killing prostitutes… you can’t control them, but I can.”[27].

This quote encapsulates how predators view certain women: as easy targets and less-than-human. Women in especially vulnerable professions or situations (like sex work, which often involves being alone with strangers) are prime targets because the killer anticipates little effective resistance.

Sexual and sadistic motives: A huge proportion of serial homicides—particularly those that garner headlines—involve a sexual element. In these cases, the killer’s primary gratification comes from domination, rape, torture, and murder as a combined experience. In patriarchal cultures, female bodies become the default canvas for that kind of violence. Women are often sexualized and objectified in everyday life; when a man with psychopathic tendencies develops violent sexual fantasies, he frequently casts women as the objects of those fantasies. The FBI’s Behavioral Analysis Unit has noted that a “large number” of male serial killers have a sexual motive, usually paired with desires for power and sadistic thrill[11][28].

Thus, the typical serial murderer profile (a male driven by twisted sexual compulsions) all but ensures that the victims will be female in many cases, because that fits the killer’s fantasy. Killing women can feel, to such offenders, like the ultimate act of control or vengeance – a way to literally consume, destroy, or “punish” the objects of their desire. It’s a grotesque extension of misogyny: the killer frames the woman as a symbol of whatever he hates or craves, then eradicates her as an assertion of power.

It’s important to note that not all serial killers target women – some kill men (e.g. Jeffrey Dahmer killed young men; some killers target male drifters or boys). But even then, vulnerability and power are key: Dahmer chose men he could render unconscious; other killers choose younger males or those at societal margins. Across the board, the victims of serial killers are typically people the perpetrator perceives as low-risk prey. For many, that means women. In fact, one study of U.S. serial murders found that the victimization rate of females in serial cases was dramatically higher than in non-serial murders precisely because of these sexual/power motives unique to serial offenders[29].

Social invisibility (the “Less Dead”): Perhaps the most disturbing reason so many serial killer victims are female is that certain women occupy positions in society that make their disappearances less likely to draw immediate, vigorous attention. Criminologist Steven Egger coined the term “the less dead” to describe the types of victims serial killers often choose – those who are marginalized and whose absences provoke little outrage or follow-up[30]. This includes categories like:

• Sex workers (prostitutes)
• Runaways and homeless women
• Women struggling with drug addiction
• Undocumented immigrant women
• Women from indigenous or minority communities with tense relations with law enforcement
• Women who are transient or estranged from family

These individuals can vanish without immediate consequence. Police might dismiss a missing person report by saying “she’s probably off partying” or note her high-risk lifestyle and not prioritize the case[31][32]. Tragically, serial killers know this and exploit it. As one detective put it,

“Officers take a chance by sloughing [these cases] off as ‘just doing drugs or prostitution,’ and they can get away with it – until that one case comes along where they should have taken it more seriously.”[32].

Cases like the Green River Killer, the Long Island Serial Killer, and Canada’s Robert Pickton all involved scores of female victims who were sex workers or marginalized women.

Law enforcement’s slow response allowed the killers to claim many more lives. Egger observed that society in general tends to view these women as having put themselves in danger, as “people who take big risks and get what they deserve.”[33] This victim-blaming mentality essentially gives serial predators a green light. They correctly sense that if they target, say, street prostitutes or hitchhikers, the public and even police will not mobilize as urgently as they would if a college student or suburban housewife went missing.

It’s a harsh truth: being part of a marginalized group (which many women are, due to poverty, race, occupation, or other factors) increases one’s appeal to a serial killer. The killer wants victims that won’t be avenged immediately. Women living on the margins sadly fit that bill more often than men, because societal biases render them “invisible.”

A compelling illustration is the case of Robert Pickton, the Canadian serial killer who preyed on dozens of women from Vancouver’s impoverished Downtown Eastside (many of them Indigenous and involved in sex work). For years, families and advocates tried to get authorities to take the disappearances seriously. Pickton later admitted to murdering 49 women. An inquiry noted that

“Pickton preyed on girls and women from this downtrodden and dangerous place, many of them Aboriginal,”

and that systemic indifference played a role in the delayed justice[34].

In sum, women are so often the victims of serial killers not because of any intrinsic weakness, but because society affords them less protection and value in these contexts. Serial killers are adept at identifying those gaps. They hunt where the victims are plentiful and the alarms are few.

5. How Misogyny Shapes Victim Selection

Serial killers don’t operate in a cultural vacuum. They marinate in the same misogynistic tropes and attitudes that pervade society – they just take those attitudes to lethal extremes. Misogyny (the hatred or devaluation of women) shapes who they target, how they commit their violence, and even how they rationalize their crimes. Consider these facets:

• Victim type and justification: As discussed, many male serial killers consciously choose women whom they label in derogatory ways. Sex workers are often viewed by these offenders as “dirty”, “disposable,” or morally debased – the killer uses that to justify murder in his mind. Gary Ridgway’s statement above is a prime example: he saw prostitutes as a societal problem and himself as solving it by killing them[27]. Likewise, Jack the Ripper famously targeted prostitutes in 1880s London under an apparent hatred for “immoral” women. Some killers fixate on women who represent someone they resent (for instance, an abusive mother or an ex-girlfriend). In interviews or confessions, they’ll speak in generalities: “those women had it coming,” “no one will miss them,” “she was asking for it.” This dehumanizing mindset is pure misogyny – it allows the killer to view his victims not as individual human beings but as symbols of a hated class. It’s much easier to kill “things” than people. By depersonalizing women as mere targets, the serial offender silences any flicker of empathy that might otherwise restrain him.
• Level of brutality: Misogyny can also be seen in the overkill and specific degradation in some of these crimes. When a serial murderer mutilates a woman’s body (e.g. targeting sexual organs, disfiguring her face) or inflicts far more wounds than necessary to cause death, it often signals rage not just at that individual, but at her identity as a woman. The crime becomes a grotesque statement: the killer literally and symbolically “destroys” womanhood. For instance, several lust killers have carved misogynistic slurs into bodies or posed victims in demeaning sexual positions. This isn’t just random brutality – it’s making a point. As one FBI profiler explained, many such offenders have deep-seated anger at women in general, and the excessive violence is an expression of that hate (a way to “punish” or humiliate women even after death)[11][28].
• Language and narrative: When investigators or psychologists talk to these killers, the misogyny comes out in how they speak about victims. Female victims are often reduced to “those girls,” “hookers,” “meat,” or “it”. For example, serial rapist-killer Edmund Kemper would describe his victims as “objects” for him to use. The Green River Killer (Ridgway) explicitly said he hated prostitutes and thought he was helping society by killing them[27]. That type of language – painting women as valueless or evil – is how misogyny directly fuels the crimes. It creates a mental permission structure for repeated violence. The killer doesn’t have to feel guilt if he’s convinced himself “these aren’t innocent people, they’re scum”. Society at large has often been complicit in this devaluation. For decades, the murder of a sex worker was not taken as seriously as the murder of a “respectable” woman. That sends a message to predators about whose lives have value. As criminologist Egger observed, there’s a common attitude that certain women “get what they deserve” – a notion which killers readily embrace[33].

In summary, misogyny provides both the targets (marginalized women) and the excuses (victim-blaming rationalizations) for many serial killers. While psychological abnormalities ultimately drive someone to become a serial murderer, the direction of their violence – whom they choose and how they justify it – often follows the ugly grooves of societal sexism.

6. The “Invisible” Victims: Sex Workers, Runaways, and the Disappeared

If you want to know where serial killers hunt, look to where people can disappear without headlines. The harsh reality is that certain victims seem “invisible” to society, and those are precisely the people serial predators target again and again:

• Street-based sex workers: Women (and to some extent transgender or male sex workers) who work on the streets are at extreme risk. They routinely get into strangers’ cars or go to secluded areas, making them easy prey. If one goes missing, it might be days or weeks before anyone reports it – sometimes fellow sex workers notice first, because families may be estranged. Even when reported, historically the response has been tepid. Police might mark the file “unfounded” or assume she left of her own accord[31]. Serial killers know this. Cases like the Long Island Serial Killer (who targeted escorts advertising online) or Gary Ridgway (who prowled Seattle’s red-light districts) illustrate how predators essentially had a “safe” victim pool. Ridgway said he picked prostitutes because their disappearances “wouldn’t be noticed for a long time” and because “police didn’t spend much time looking for them”[26][30]. In other words, these women were invisible enough for him to kill dozens over nearly two decades.
• Runaway and homeless youth: Teenagers who have run away from home or been kicked out (often due to abuse, drugs, or LGBTQ+ issues) frequently end up living rough or in shelters. Young women in that situation may resort to survival sex or travel alone. Predators like (the fictional Buffalo Bill in Silence of the Lambs was based on this concept) and real ones like Atlanta’s 1980s serial killer (who targeted young Black women on the streets) often strike here. These victims have little support network to sound an alarm. A homeless woman might go missing and no official missing persons report is ever filed because she has no one to file it. A transient teen might be presumed to have moved on to another city. This lack of a safety net means a serial killer can claim multiple victims in this population before patterns emerge.
• Victims of domestic violence or addiction: Women who are deep in substance abuse or in abusive relationships can also become “invisible” in a way. An abusive partner might not report her missing at all (or might be wrongly assumed by police to be the culprit, distracting from a serial killer if one is involved). If a woman has a history of drug arrests, police might not treat her case with urgency, assuming she could be on a bender. Serial predators have been known to lurk around drug treatment centers, homeless encampments, or neighborhoods known for high crime – precisely because the people there already occupy a low priority in the system.
• Indigenous and minority women: In some regions, indigenous women and women of color go missing at disproportionately high rates and get disproportionately low media coverage. For instance, on some Native American reservations and in Alaska, indigenous women have been murdered or disappeared in alarming numbers, leading to what’s now called the Missing and Murdered Indigenous Women (MMIW) crisis. Serial killers like Robert Pickton targeted indigenous women in Canada, and it went unnoticed for years partly due to systemic biases. As one report on Pickton noted, many of his victims were indigenous and the police “would not listen” to community warnings until very late[34][35]. The same pattern has been observed with African-American sex workers in some U.S. cities – their cases get scant attention, allowing a serial predator (who may even be Black himself) to continue operating.

In all these scenarios, the through-line is lack of institutional urgency. Families of these “invisible” victims often complain that they tried to get authorities to care. For example, the father of 20-year-old Tia Hicks (a Seattle woman who struggled with drugs and was later found to be a serial killer’s victim) reported her missing in 1990, only to have the case essentially ignored and purged from the system[31]. Police assumed she was “just off doing drugs.” In fact, she had been murdered. A detective later lamented that if such missing persons were consistently taken seriously, some serial murders could be prevented[36][37].

Serial killers ruthlessly exploit the hierarchy of victim value. They know who will be searched for and who will be shrugged off. The uncomfortable truth is that society’s prejudice and apathy towards certain groups of women literally enable serial killers to thrive. Combatting that means treating every missing person case with dignity and urgency – because a pattern might only be visible if someone’s looking in the first place[36][30].

7. How Female Serial Killers Operate Differently

When women are the serial killers, a few consistent differences emerge in how they commit their crimes. These contrasts to male killers are crucial for investigators and also illuminating from a gender perspective:

Method: Less “spectacular,” more insidious. Female serial killers rarely engage in the kind of overt, bloody violence seen in many male-perpetrated serial murders. They are far less likely to use guns, knives, or physical force to subdue strangers. Instead, women tend to use quieter, harder-to-detect methods[7][38]. Poison is a classic choice – it can be administered in food or drink and masquerades as illness. Overdose by medication is another (especially for nurses or caregivers with access to drugs). Suffocation or smothering (for infants, elderly, or incapacitated victims) is also common.

These methods don’t create gory crime scenes; often the death at first appears natural or accidental. A 2006 study found poisoning was the preferred method among female serial killers interviewed[7]. Another review noted that women “favor harder-to-detect methods such as poison or asphyxiation,” which disguise their crimes[38].

This isn’t to say female killers are any “nicer” – administering antifreeze in a drink is just as lethal as shooting someone in the head – but the style is different. Women’s crimes often require a longer game (waiting for poison to take effect, repeating doses, etc.), and they allow the killer to avoid direct confrontation. This style may be partly due to physical considerations (a woman might not relish a hand-to-hand struggle with a victim), but it’s also a learned behavioral pattern: women are conditioned to be subtler in aggression. The downside for law enforcement is that female serial murders can fly under the radar much longer.

If someone is stabbing victims on the street, police see a homicide and might link cases. If someone is quietly overdosing hospital patients, it might just appear as a bad month in the ICU. As author Peter Vronsky notes,

“Female serial killers kill covertly… Police won’t likely know it’s homicide until they string together a series of deaths that are statistically unlikely – a hospital setting, numerous dead spouses, many dead children.”[39].

They are “quiet” killers in that sense, leaving few outward signs.

Environment: Domestic and institutional. While male serial predators often prowl highways, college campuses, parks, and other public or transitory spaces, female serial killers usually operate in places where they are already embedded in a relationship with the victim[8]. Common settings for female serial killings include the home (killing family members, roommates, or lovers), nursing homes or hospitals (for nurses/caretakers who kill patients), and other caregiving environments like daycare centers. They seldom hunt strangers in the streets.

One study comparing genders found male serial killers were almost six times more likely to kill a stranger, whereas female serial killers were about twice as likely to kill someone they knew[25]. Women serial killers “gather” their victims around them, often targeting people already in their orbit (who trust them), rather than stalking strangers afar[40][41]. Harrison, the evolutionary psychologist, even analogizes that men are “hunters” while women are “gatherers” when it comes to serial murder – men travel and stalk, women kill in their own homes/workplaces where victims come to them[42].

This difference in locale means less “stranger danger” and more betrayal of trust in female-perpetrated cases. Victims of female serial killers are often those who depended on the killer: children, elderly parents, patients, spouses. There’s a grim irony that society worries about an anonymous fiend, when sometimes the danger was the friendly nurse or the dutiful wife. Because women killers stick to their circles, they can sometimes claim more victims before detection.

For example, Beverley Allitt, a British nurse, killed 4 infants and harmed 9 others in a children’s ward in 1991 by injecting them with insulin or air. It took unusually high cardiac arrest rates in that ward to prompt an investigation, because each case alone looked like a medical tragedy. In family settings, a woman who sequentially murders two or three husbands over a decade might get away with it if each is chalked up to health issues. Only when patterns (like multiple dead spouses or multiple insurance payouts) emerge does suspicion catch up.

Motive patterns: power, profit, and “care” (warped caregiving or mercy). As mentioned earlier, the motives driving female serial killers skew differently from the sexual predator motive common among males. Female killers are rarely in it for an erotic thrill. Instead, their crimes often have a goal or delusion attached:

• Financial gain: A large subset of female serial killers do it for money. They might systematically eliminate relatives or clients for life insurance, property, or theft. These are the “black widows” and “comfort” killers described. The motive is greed, plain and simple. For instance, Judy Buenoano poisoned her husband, boyfriend, and son (and attempted to kill a fiancé) for insurance payouts in the 1970s-80s. Such motives are calculated and cold, but not sexually driven.
• Power/control in caregiving: Another significant motive is the “God complex” or power trip that some caregivers have. In cases of nurses or home aides who kill, the motive is sometimes described as a need for control or attention. They might create medical emergencies to feel the excitement of resuscitating (as was the case with nurse Kristen Gilbert, who induced heart attacks in patients so she could heroically “save” them, killing four in the process)[43]. Others enjoy having the ultimate power over life and death. Harrison noted that in nurses who kill, often “power, not profit, tends to be the motive”[44]. These women seek the rush of being in control, sometimes rooted in a history of feeling powerless earlier in life[44]. For example, if a nurse had a traumatic upbringing, exerting life-and-death decisions can psychologically compensate for past helplessness.
• Perverted “Mercy” or Mission: Some female serial killers rationalize their acts as merciful or necessary. A mother might kill her children believing she’s saving them from a cruel world (this overlaps with mental illness in cases like Andrea Yates, who drowned her 5 children in 2001 under psychotic delusions). A nurse might claim she ended suffering of terminal patients (whether or not the patients or families wanted that). There are also cases of women with a “mission” orientation – e.g. Josephine Gray, who was suspected of killing two husbands and a boyfriend, possibly believing she was ridding herself (and the world) of “bad men.” These motives are often entangled with psychological issues and are sometimes treated with more sympathy by courts (if framed as mental breakdown or overzealous mercy).
• Complicity or coercion: In team scenarios, a woman’s motive might simply be devotion to her partner or fear of them. Myra Hindley, for instance, assisted Ian Brady in the Moors Murders of children in 1960s England, later claiming she was under his sway. Karla Homolka in Canada helped her husband rape/kill girls (including her own sister), and she portrayed herself as an abused victim to get a lighter sentence. Whether one believes those claims or not, their stated motive was love/fear. There are also thrill-seeking pairs where both parties are in it for mutual kicks (like the two teen girls in England who murdered a woman for “fun” and posted on social media about it[45]).

Overall, female serial killers frequently have a utilitarian or relational motive rather than a lustful one[46]. They are trying to get something (money, relief from caregiving, attention) or get rid of something (an inconvenient person, a perceived burden). Even in the rare case of a woman with sexual motives (like nurse Jane Toppan in the 1890s, who reportedly got a sexual thrill from poisoning patients), the approach is covert and relational (she killed people she cared for). This contrasts with the archetypal male pattern of killing strangers for a paraphilic high.

To investigators, these differences mean that profiling a serial killer must account for the possibility of a female suspect, especially when the crimes involve poisonings, care settings, or family deaths. Historically, many female serial killers evaded detection precisely because nobody suspected “a nice woman”. As Monroe (the FBI agent) advises, detectives must actively ask “Could a woman have done this?” and not assume the offender is male by default[47]. Failing to do so is one reason women like the “Angel of Death” killers have racked up high victim counts before capture – they were hiding in plain sight, doing things that didn’t set off the traditional serial killer alarms.

8. Case Snapshots: Bathory, Wuornos, and the Caregiver Killers

To ground these patterns, let’s look at a few examples of female serial killers and how they illustrate (or break) the rules:

Elizabeth Báthory – The “Blood Countess”: A historical outlier, Elizabeth Báthory is often cited as one of the first known female serial killers. A Hungarian noblewoman in the late 16th and early 17th century, she was accused of torturing and murdering a large number of young women – perhaps dozens, or even hundreds (legend puts the number at over 600)[48]. Báthory was a countess with her own castle and servants.

According to testimonies from the time, she lured or forced servant girls and local peasant daughters into her household, then subjected them to horrific cruelties: sticking needles under their nails, covering them in honey and leaving them to be bitten by insects, burning or freezing them, biting their flesh, and other sadistic acts[49]. Many died from this torture, and Báthory allegedly disposed of the bodies secretly.

What makes Báthory’s case remarkable (aside from the body count) is how class and gender intersected. Because she was an aristocrat, authorities were reluctant to act on rumors of her crimes for a long time. In fact, it wasn’t until some minor noble girls (wardssent to her for education) fell victim that the Hungarian officials seriously investigated. Mistreatment of servants and peasant girls was largely ignored – those victims were “less dead” in that feudal society[50].

When Count Thurzó finally raided her castle in 1610, the legends say they caught Báthory in the act of tormenting a girl. She was never executed or tried like a commoner; instead, as a wealthy woman of high status, she was confined to a tower in her castle for the remaining years of her life[50]. Her accomplices (servants who helped procure victims) were executed, but Báthory was essentially given a house arrest punishment due to her nobility[50].

Báthory’s story, though shrouded in folklore, showcases a female perpetrator exhibiting a level of sadism usually attributed to male “sexual psychopath” killers. Some have even speculated she had sexual motivations in her torture of girls[49], but it’s impossible to know. Regardless, she defies the myth that women can’t be as cruel as men. The reactions to her also highlight a tendency to rationalize or mythologize female violence – in the centuries after, she was often depicted as a vampire countess (legend says she bathed in virgins’ blood to stay young, though there’s no contemporaneous proof of that)[51].

Rather than see her as a calculated serial killer, people framed her as a supernatural monster or as “insane.” This mirrors a pattern we see even today: female serial killers often get the narrative of madness or otherworldly evil, as if trying to separate their acts from normal womanhood. In truth, Báthory was likely a psychopath who found a context (her absolute power over subordinates) in which she could kill with impunity. Her case sits at the extreme end of female serial killing – a sexually sadistic, high-body-count offender, shielded by privilege.

Aileen Wuornos – A Rare “Male-Pattern” Female Serial Killer: Aileen Wuornos is one of the very few modern female serial killers who fits many of the “typical” male serial killer traits, which is why her case has fascinated the public. Wuornos was a Florida sex worker who, between 1989 and 1990, killed at least six (and possibly seven) male clients she solicited along highways[52]. She would ride with these men, then shoot them at point-blank range and rob them. Unlike female serial killers who kill quietly or those who kill people they know, Wuornos targeted strangers and used a firearm – both very uncommon for female offenders[53].

Wuornos initially claimed she killed in self-defense, alleging that the men had either raped or attempted to rape her. Indeed, her first victim was a man who had a record of sexual violence, and there were signs of a violent struggle. However, as the killings continued, it became clear Wuornos was also acting out of anger and perhaps a skewed sense of vengeance against men in general. Her life was marked by abuse: she was sexually assaulted in childhood, beaten by caregivers, and forced to survive via prostitution from a young age.

She harbored deep rage towards men, telling acquaintances she hated them. In psychological terms, Wuornos’s motives blended personal revenge, financial gain (she took cash and cars from victims), and possibly a twisted sense of “control” over a world that had harmed her. One expert noted, “Wuornos was driven to kill men out of rage and a desire for vengeance… retaliation for a lifetime of rape and beatings”[54]. In essence, she flipped the predator-prey script: a woman killing predatory men.

Wuornos’s crimes were brutal and lacked subtlety – she left bodies on the roadside. This brought law enforcement attention relatively quickly (compared to, say, a nurse poisoning patients). She was caught after a year, convicted of multiple murders, and in 2002 became the first woman executed for serial murder in the U.S. in modern times. Her story became the subject of the film Monster (2003), where Charlize Theron portrayed her, highlighting both her victimization and her violence.

It’s important to note that Wuornos is not representative of female serial killers generally. She is an outlier, often referred to as the “Damsel of Death” in media. People sometimes call her “America’s first female serial killer,” which is inaccurate historically, but speaks to how unusual her case seemed. She killed like a lone highway predator, a role almost exclusively filled by men. Wuornos herself acknowledged at times that she killed from hate and fury. In prison interviews, her instability and anger were on full display.

She doesn’t easily fit any single typology: not a black widow, not a pure lust killer, not a caregiver. If anything, she’s closest to a “mission-oriented” killer (in her mind, eliminating men who would rape women) combined with personal rage. Wuornos’s infamy has somewhat skewed public perception – making people think female serial killers might be more like her than they really are. In truth, cases like Wuornos come along perhaps once in a generation. Most female serial killers are far less “movie-ready” in their stories.

“Angels of Death” – Nurses and Caregiver Killers: For a broader snapshot, consider the numerous cases of medical professionals who turned serial killer. These cases illustrate the quintessential female pattern of repeated murder under the cover of caregiving. A few examples:

• Genene Jones: A pediatric nurse in Texas, suspected of killing between 11 and 46 infants and children in the 1970s-1980s by injecting them with drugs like heparin to induce medical crises. She seemed to crave the excitement of responding to the emergency she created, sometimes “saving” the child and other times not. Because infant deaths can happen, it took years and many suspicious codes before she was caught.
• Beverley Allitt: A British nurse (mentioned earlier) who killed 4 infants and attempted to kill more by insulin and air injections in 1991. She appeared as a sweet, attentive nurse – even comforting parents of kids she had secretly murdered. Her motive seemed to be a need for attention (some speculate she had Munchausen syndrome by proxy, deriving psychological benefit from creating medical emergencies).
• Kristen Gilbert: A nurse at a Veterans Affairs hospital in Massachusetts, convicted of murdering 4 patients in the 1990s. She injected adrenaline to trigger cardiac arrests, then often “discovered” the codes and participated in the futile resuscitations[43]. Coworkers called her the “Angel of Death” after suspicions arose. Her motive, as pieced together, was partly the adrenaline rush and possibly to impress a security guard she was romantically interested in (being in the center of dramatic events).
• Lucy Letby: A very recent case (2015-2016) in the UK. Letby was a neonatal nurse convicted in 2023 of murdering 7 newborn infants and attempting to kill 6 others – making her one of the worst medical serial killers ever documented. She did things like inject air into babies’ bloodstreams, overfeed them milk, or poison them with insulin[19]. The case shocked the public because of how completely Letby violated her role. As one investigator remarked, “Would you think that a trained, skilled nurse would be capable of… brutalizing a baby?”[55]. Her motive remains unclear – prosecutors implied it was attention-seeking or a desire to “play God.” Letby fits the pattern of an unassuming woman who exploited trust to kill the most vulnerable victims imaginable.

These “caregiver” cases highlight how female serial killers operate differently in practice and how they can evade detection. In each, the method was subtle (no obvious violence, just a patient suddenly crashing). The environment helped conceal the crimes (hospitals expect some deaths, especially among the old or very young). And the motives often boiled down to a pathology around control and attention, rather than financial gain or sexual sadism. Society’s image of women as natural caregivers actually facilitated these crimes – colleagues and supervisors found it hard to imagine a female nurse intentionally harming patients, sometimes explaining away evidence that, in hindsight, looks glaring.

One chilling aspect of many caregiver killers is the high body count they achieve. Some male serial killers like Bundy or Ridgeway racked up dozens of victims over years by evading capture. Female medical killers have likewise killed dozens – but without ever leaving their workplace. For instance, Charles Cullen (a male nurse) and Jane Toppan (female nurse) are each suspected of 30+ murders. The “advantage” these killers have is that each death draws little scrutiny individually.

Only data and diligence can catch them (like noticing one nurse is present at an inordinate number of codes). Modern hospitals now have protocols to detect anomalies, but it’s still possible for an “angel of death” to operate for a long time, as Letby’s recent case shows. This is a uniquely female corner of serial murder, as women dominate nursing roles and thus have more opportunity in that realm. It’s the dark flip side of the nurturing stereotype – the trusted caregiver who is actually a predator.

9. Media Distortion: Angels, Monsters, and “Black Widows”

The way the media portrays female serial killers is often very different from how male killers are portrayed, and this distortion affects public perceptions. Some common media tropes and their implications:

• The Black Widow stereotype: As mentioned, media loves the image of a seductive woman who marries and murders for money. While black widows exist, not all female serial killers fit this (many aren’t particularly seductive or glamorous). However, films, TV shows, and news headlines often lean into the “femme fatale” angle – emphasizing if the woman was attractive, had multiple lovers, etc. For instance, when a woman like Stacey Castor (who killed two husbands with antifreeze) is covered, press called her a black widow and focused on her manipulative charms. This simplifies the story to a one-dimensional caricature: greedy vixen poisons men.
• The Angel of Mercy turned Angel of Death: When a nurse or mother is a killer, media often express bafflement at the violation of feminine care roles. They use language like “angel of mercy gone wrong” or emphasize the maternality (“mother of 3 accused of…”) to accentuate how shocking it is. Sometimes they imply sympathy or an excuse – e.g. suggesting the nurse was “overwhelmed” or the mother had mental illness. In Letby’s case, despite her conviction, some press still clung to disbelief because she seemed so normal and even shy in demeanor. There is often a subtle undercurrent of “how could a woman, of all people, do this?” that you don’t see when a man is arrested for serial murder (no one asks how a man could be so violent – it’s sadly less surprising).
• Madness and victimhood narratives: Female killers frequently get framed as either mad or manipulated in media accounts. A male serial killer might be labeled a “monster,” but a female is more likely to be described with terms that suggest she’s not fully in control of her actions. For example, “Mother on rampage driven by postpartum psychosis”, or “Woman under lover’s spell participates in killings.” This narrative can sometimes be true (mental illness and coercion do occur), but it’s notable how often it’s applied. Even a case like Bathory’s, over time, evolved into a legend of insanity and vampirism rather than straightforward criminality. When Charlene Gallego was arrested with her husband Gerald for a series of sex-slave murders, media speculation quickly arose that she was another victim, despite evidence of her willing participation. We tend to seek an external reason for female violence – either a man behind it or a mental break – whereas with male serial killers we more readily accept that they chose to do evil of their own accord.
• Sexualization or othering: Sometimes the media does the opposite and paints the female killer as a hypersexual deviant or a witch-like figure. Aileen Wuornos was branded the “Damsel of Death” and often described in almost pseudo-sexual, derogatory terms (e.g., focusing on her appearance, her sexuality, her mannerisms) in a way male killers weren’t. Another example is Ilse Koch (the WWII concentration camp overseer who abused prisoners) – she was called “the Witch of Buchenwald” and fixated on as a depraved nymphomaniac in press accounts, highlighting her deviance from womanly norms. By emphasizing how these women are not like normal women, media create a comfortable distance: these are not our mothers, sisters, or nurses; they are monsters or temptresses. It’s a way of resolving the cognitive dissonance of female aggression.

Meanwhile, victims tend to get lost in these narratives, but even more so in female-perpetrated cases. When a male serial killer is covered, the focus is often on the gruesome details or the man’s psychology, with victims sometimes becoming names in a list (unless their families push back). In female killer cases, the victim profile can get especially sidelined. For instance, in coverage of those nursing home killers, you’ll often find more ink spent on “what drove Nurse X to do this” than on who the victims were (elderly folks whose families’ grief gets comparatively little coverage).

In black widow cases, the media may show pictures of the femme fatale at court more than the deceased partners. It’s as if the story either casts the woman as a fascinating aberration of womanhood or as a pitiable figure who snapped – in both scenarios, the actual people killed don’t get the focus they deserve.

Finally, media distortion affects public awareness. Before Aileen Wuornos, many people literally did not know female serial killers existed in the modern day. Law enforcement too was affected – recall that FBI profiler saying “no female serial killers” in 1998[2]. Since Wuornos, the pendulum swung a bit – but often towards sensationalizing any rare case (like the recent one of Joanna Dennehy in the UK, or even unconfirmed serial allegations like one against nurse Lucy Letby before trial, which UK media speculated about heavily).

There’s still a lack of nuanced understanding. Female serial killers are either “Black Widows, Angels, or Mannish Monsters” in popular imagination. The reality is more complex: they are criminals shaped by many of the same forces (abuse, psychopathy, opportunity) as male killers, just filtered through a different social role.

The media, by distorting these cases, can hamper investigations (if police don’t believe a woman could be responsible) and impede prevention (by making us think only men with a certain “look” are dangerous). As we move forward, more balanced coverage – that treats female offenders as people responsible for their actions without either demonizing or excusing them on the basis of gender – would help the public grasp the true nature of the threat.

10. What This Means for Prevention and Justice

Understanding the gender patterns in serial murder is not just trivia – it has real implications for how we try to prevent these crimes and deliver justice for victims. Here are a few takeaways:

Rethinking victim protection: Since most serial killers are men and most victims are women (especially marginalized women), our traditional safety advice and policing priorities need adjustment. Public safety campaigns often emphasize “stranger danger” for children or caution women not to walk alone at night. While being aware of surroundings is fine, the reality is that serial killers deliberately target those whom society neglects. Therefore, police and communities must take reports of missing women seriously, regardless of the woman’s lifestyle. If a sex worker or drug user disappears, it should trigger as urgent a response as any other missing person – because it could very well be the first visible sign of a serial predator.

In many infamous cases, had authorities acted on early missing persons reports (often filed by families or friends who knew something was wrong), later murders might have been prevented[36][37]. Prevention means allocating police resources to “high risk” areas not to harass the women there, but to protect them – for instance, providing a means for sex workers to check in safely, or monitoring patterns of assaults in those communities. It also means society at large must shed the attitude that some victims are “less important.” Every life matters; serial killers count on us forgetting that.

Monitoring caregiving environments: Because a significant chunk of female serial killers operate in caregiving roles (nurses, aides, etc.), healthcare and eldercare systems need better checks for foul play. This includes tracking unusual clusters of deaths. Hospitals and nursing homes should use data analytics to flag if one staff member’s shifts have markedly higher mortality rates than others (adjusted for patient condition). In the past, this kind of pattern often only came to light after whistleblowers spoke up or a belated investigation.

Institutions must also overcome the bias of assuming “she’s a good nurse, she couldn’t be harming patients.” Whistleblower protections are vital – many nurses who tried to speak up about suspicious colleagues were initially ignored or even punished. Now, some countries have policies: multiple unexpected codes on one ward prompt an automatic review. Similarly, home care agencies could implement random checks or ensure multiple caretakers rotate (so one person isn’t left alone with a vulnerable individual for long periods unchecked, which could deter would-be abusers).

Another aspect is forensic pathology alertness: Medical examiners should be educated that serial homicide via subtle means is a thing. A middle-aged man dying of what looks like a heart attack might actually have been injected with something – if he’s the third such case connected to the same nurse, for example, that should ring alarm bells. Multidisciplinary teams (doctors, police, psychologists) might need to collaborate when there’s a gray area between natural death and possible homicide in caregiving settings[47][56].

Challenging stereotypes in investigations: Law enforcement training needs to emphasize that serial killers are not always the white male loner of popular lore. Profiles should include the possibility of a female, especially if evidence points that way (e.g. poison, domestic victim pool, etc.). Investigators must check their biases – as Monroe said, they should ask “Could a woman have committed this crime?” early in the case, not as an afterthought[47].

A historical example: in the 1980s, when several children at a California hospital were being poisoned, the idea that a nurse (female) was responsible was so unthinkable that it delayed the investigation’s focus on the actual killer (nurse Efren Saldivar, who was male, but initially suspicion bypassed nurses altogether). Conversely, when women are suspects, investigators shouldn’t automatically buy the “male accomplice made me do it” story without evidence. Each case requires looking at the facts objectively, not through a lens of “women are incapable of that level of violence” or “women are always under a man’s influence.”

Addressing misogyny and violence broadly: The link between everyday misogynistic violence and the extreme end of serial femicide suggests that prevention of serial killing starts much earlier. Many serial killers escalate from less-lethal crimes: stalking, domestic abuse, sexual assault, torture of animals, etc. These are often crimes with gendered patterns (e.g., domestic violence overwhelmingly involves male aggressors, female victims).

If society and the justice system rigorously addressed violence against women in its more common forms, some future serial killers might be incapacitated or reformed before they get that far. For instance, several serial killers had prior arrests for attacking women but received light sentences or slipped through the cracks. If those had been taken more seriously (with psychological intervention or longer incarceration), maybe the later murders wouldn’t occur.

Additionally, educating the public – especially young men – about healthy attitudes toward women and about the dangers of dehumanization is important. This is obviously a broad goal, but it ties in: the more we treat misogyny as unacceptable, the fewer individuals will find validation in communities of hate (for example, the so-called “incel” subculture, which in a few cases has produced would-be serial killers targeting women). Some serial killers essentially formed their worldview from a mix of personal trauma and societal misogyny. We can’t stop the trauma in every case, but we can work on the misogyny part.

Support for high-risk individuals: On the victim side, providing resources to the most vulnerable women can indirectly thwart serial predators. Things like shelters for sex workers, addiction treatment, mental health services, and robust missing-person investigations all make it harder for a predator to amass victims. When women have escape routes from the streets or abusive situations, they’re less available to be preyed upon.

One interesting initiative some cities have tried is a “bad date list” for sex workers – essentially a network where they share information about dangerous clients. Such networks could potentially flag a serial killer early if several women report narrowly escaping violence from the same guy. Police often ignored sex worker reports in the past; integrating these community warning systems with law enforcement could save lives.

In the end, the phenomenon of serial murder – though rare – shines a flashlight on larger issues. The gender imbalance in offender vs. victim tells us about power imbalances in society. To reduce serial killing, we have to reduce those imbalances: value all lives equally, train ourselves to see through stereotypes, and hold perpetrators of any violence accountable, regardless of gender. The lives lost to these killers demand that we learn these lessons and apply them.
