Initial crimes Following the divorce, Yarovoy resigned from his workplace and started living on the streets. In 1990, he was found guilty of raping a woman in
Boralday, for which he was sentenced to 3 years imprisonment. Yarovoy was quickly arrested, tried and convicted for this, receiving a 15-year sentence. He was then transferred to serve it in a
penal colony near Ust-Kamenogorsk, in
East Kazakhstan.
Serial murders Between August 2006 and 2008, Yarovoy committed a series of at least 9 rapes and 6 murders against children and women in Ust-Kamenogorsk and Opytnoye Pole. His
modus operandi consisted of attacking victims in deserted areas such as vacant lots or near railroad tracks, sneaking up on them and hitting them on the back of the head with a blunt object such as a steel pipe. If the victim was knocked out successfully, he would then rape and sometimes beat them to death. He had no definitive victim type, as he killed both children, teenagers and women with age ranges from 8 to 50, with differing physical features and ethnicities. According to Yarovoy, they only thing that mattered was if there were no possible witnesses to an attack. A few months later, he came across a woman late at night who was in a hurry to catch a train on the "Zashchita" railway station. Yarovoy caught up with her and threw her to the ground, but the victim fiercely resisted him, causing them both to roll down an embankment. Once they reached the bottom, Yarovoy managed to put his hand over her mouth, get on top of her and hit her with a rock. He then raped the woman and subsequently killed her before fleeing the area. In the summer of 2008, Yarovoy killed a 16-year-old teenage girl and a 30-year-old woman near Opytnoye Pole, both of which occurred within a short time frame of one another. ==Arrest and confessions==
