In 1999, Osipenko moved from his native Kazakhstan to the city of Rossosh, settling on the market to sell products to other vendors.
Osipenko committed the murders in a pattern: he would follow his victim, who lived in five-storey houses on the upper floors, go into the apartment with them, then rape and kill the owner, before plundering the place.
He then forced her to go to the bedroom, cut off her clothes, taped her mouth with a plaster, raped and finally killed her with a piece of metal pipe.
In late September 2006, the Voronezh Regional Prosecutor's Office forwarded the Osipenko case, consisting of 16 volumes, to the court.
But on 7 December, the Voronezh Regional Court delivered a verdict, according to which Osipenko was found guilty and did not deserve leniency.
