Oleg Murayenko

Oleg Vasilyevich Murayenko (; 1973 – 2002) was a Kazakhstani serial killer responsible for the murders of six women in Petropavl between March and November 2000, after being erroneously released from prison after killing an inmate in 1998. Following a lengthy investigation and his capture with the use of fingerprints, he was convicted, sentenced to death and executed in 2002.

Biography Little is known about Murayenko's background. Born in 1973 in Petropavl, he was popular with girls and women from the town, whom described him as a tall and handsome man, akin to a Kazakh Alain Delon. Despite this, Murayenko was first prosecuted at the age of 17, and by the time he reached 25, he had amassed three convictions for robbery and theft. While serving his latest sentence at a prison colony in Novoukrainka, Aiyrtau District, he joined a prison gang called the "Council of Law and Order". On the night of November 19th to 20th, 1998, Murayenko, together with several other members, attacked a group of inmates who had refused to join their gang, beating one of them to death and leaving the other three with fractured ribs, tibias and damaged internal organs. They forwarded the information to the detectives, who in turn told Murayenko. After he was confronted with this information, he finally admitted to the crimes, explaining in detail how he killed them and where. Despite this, when he was brought to trial, he recanted his confession, admitting responsibility solely for the second murder. Prosecutors were able to accurately present their evidence, however, and after a long trial, Murayenko was found guilty and sentenced to death. He was executed in 2002, which was one year before the moratorium on the death penalty was introduced in the country, thus making him the last known prisoner executed in the North Kazakhstan region.
