In October 2018, Maksym and Yaroslav Kostiukov murdered Yevhen Petrov in a Kharkiv, Ukraine apartment. Following the killing, the father and son decapitated and dismembered the victim’s body, scattering his remains across multiple locations to conceal the crime.
Although law enforcement reported evidence that human tissue was cooked and consumed, both defendants later denied cannibalism. In 2020, both men were convicted of aggravated intentional murder and sentenced to fifteen years in prison, with no separate conviction for cannibalism or ritualistic crime.

Murder conviction. Postmortem mutilation. Disputed cannibalism allegations. No ritual finding.
Kostiukov Case: Key Facts
The core facts before the cannibalism label takes over the record.
What Happened in the Kostiukov Case?
Yevhen Petrov was killed in a Kharkiv apartment after drinking with Maksym and Yaroslav Kostiukov. His body was decapitated and mutilated, his torso was later recovered near a basement, and his head remained in a box or bag on the apartment balcony. Both defendants were convicted of aggravated intentional murder in 2020.
Were They Convicted of Cannibalism?
No separate cannibalism conviction was entered. Police and prosecutors described evidence that human tissue had been cooked and consumed, but both defendants later denied cannibalism. The conviction was for aggravated intentional murder.
Who Was Yevhen Petrov?
The victim entity comes before the sensational body-recovery narrative.
Yevhen Petrov
Petrov was a 45-year-old Kharkiv resident and former patrol-service employee. Reporting describes unemployment and alcohol misuse, but those details explain vulnerability rather than reducing the seriousness of his death.
He had an ex-wife and a son. Trial reporting says relatives sought compensation, and his former wife had to identify him from the recovered head.
Not a Body-Part Inventory
The case should not reduce Petrov to gore, “human broth,” a former job title, or a cannibalism headline. The offence began with the killing of a person and continued through the destruction and attempted concealment of his remains.
What Is Confirmed in the Kostiukov Case?
Court findings, physical evidence, statements and later denials occupy different evidentiary levels.
Aggravated Murder
Both defendants were convicted of intentional murder committed with particular cruelty and by prior agreement. Each received a fifteen-year prison term.
Mutilation
A decapitated body was recovered near a basement. The head was recovered from the apartment balcony, and broad tissue loss and missing organs were described in public reporting.
Consumption
Police described frozen tissue and cooked liver. Yaroslav initially implicated his father, but later courtroom positions denied cannibalism or challenged the reliability of early statements.

No Ritual Finding
The public evidence supports murder, mutilation and disputed consumption allegations. It does not establish an occult group, ritual symbols or ceremonial motive.
Kostiukov Case Timeline: 2018 Murder to 2020 Verdict
The encounter, killing, concealment, discovery, investigation and judgment.
| Date | Event | Evidence standard | Why it matters |
|---|---|---|---|
| 3–4 Oct 2018 | Petrov meets the Kostiukovs and drinks with them before entering the apartment. | reported / date conflict | Public accounts differ on exact date, but the apartment encounter is the start of the case narrative. |
| Apartment gathering | An argument escalates into a fatal knife assault. | court narrative | Supports joint participation rather than simple postmortem assistance. |
| Following day | Petrov’s body is decapitated and extensively cut. | physically corroborated | Postmortem conduct becomes central to aggravation, cannibalism reporting and media framing. |
| 11 Oct 2018 | The torso is found near a basement entrance under garbage bags. | documented recovery | Transforms a missing-person case into a homicide and concealment investigation. |
| 13 Oct 2018 | The defendants are detained; the head is recovered on the apartment balcony. | police release | Directly links the residence to the victim and collapses the disposal strategy. |
| 5 May 2020 | Both men are convicted and sentenced to fifteen years. | court outcome | Final public conviction point; no verified appeal outcome is included here. |
Did the Kostiukovs Eat Human Flesh?
The most searched question requires careful language: alleged consumption, not a separate cannibalism conviction.
Stored, Cooked, Consumed
Police and prosecutors publicly described evidence that human tissue was stored in a freezer, liver was cooked and eaten, and the son became ill after consuming it. The son’s early account reportedly implicated his father in boiling and eating flesh.
Later Denials
Both defendants later denied eating human flesh. Defence positions challenged the reliability of early statements. The legal conviction was for aggravated murder; cannibalism was part of the factual allegation and media identity, not a separate verdict label.
Were They Convicted of Cannibalism?
No separate cannibalism conviction was entered. The responsible language is “reported cannibalism,” “cannibalism claims,” “alleged consumption” or “police said human tissue was cooked and consumed.”
Cannibalism Topic Cluster
For broader context, link this case to other documented and alleged cannibalism cases, but avoid turning the dossier into a random cannibal-offender link farm.
Was the Kostiukov Murder an Occult or Ritual Crime?
Extreme postmortem mutilation and alleged cannibalism do not automatically prove ritual motive.
No Ritual Record Located
No evidence located for this dossier establishes a ritual or occult motive. The accessible sources do not show ritual symbols, ceremonial planning, a known occult group, sacrifice language, written doctrine or religious motive.
Occult Labelling Risk
The case can be discussed beside documented occult and ritual crime only as a classification boundary: how investigators distinguish evidence from sensational labelling.

Kostiukov Trial, Conviction and 15-Year Sentences
The verdict resolved murder liability but left appeal reporting and some forensic details incomplete in public sources.
Maksym Kostiukov
Trial reporting assigned the stabbing role to Maksym, while police and prosecution sources connected him to postmortem handling and alleged consumption. He denied eating human flesh at trial.
Yaroslav Kostiukov
Trial reporting described Yaroslav restraining Petrov during the assault and assisting with dismemberment. Early statements attributed consumption to his father; later defence accounts challenged that version.
15 Years Each
Both men received fifteen-year prison sentences in May 2020. Prosecutors had sought life imprisonment and reportedly discussed appeal; a publicly verified final appellate outcome was not located in the supplied audit.
