When carrying out the murders, Bondarenko demonstrated a particular
modus operandi - once he attacked his victim, he would threaten them with physical violence, after which he would rape and strangle them. After committing each murder, he stole money and jewelry from the victim, some of which he would give to his wife. During a conversation with the woman, Bondarenko persuaded her to let him walk her home. After making sure that there were no pedestrians around, he beat, raped and strangled her. At the time, Bondarenko was never considered a suspect, and the murder remained a
cold case until he was linked to it years later. A silver chain and a cellphone were stolen from the victim. Bondareko later claimed that he stripped off the victim's clothing and dragged her to a nearby pit, before fleeing in the direction of Matrosa Koshki Street. A year later, on 16 December 2010, Bondarenko was returning home late at night to his home on Prospekt Pobedy, when he came across a 26-year-old accountant whom he attacked, raped and strangled to death. Her nude body was then left in a puddle. At the time of her death, the victim was returning home from a date with a man and was only 150 meters away from her house on General Melnik Street. On 1 February 2011, Bondarenko was riding a cab with a female passenger, noticing that she was wearing jewelry. He got out on Prospekt Pobedy and stalked her until she reached Akmolinskaya Street. After making sure that there was nobody around, he attacked the woman, threw her to the ground and attempted to rape and kill her. The victim resisted him fiercely and bit his hand, allowing her time to escape. Bondarenko fled almost immediately, fearing that he would be caught if he stayed around. Following the Russian annexation of Crimea, Bondarenko is known to have committed two murders. The first of these occurred on 23 December 2014 in the Victory Park, where he raped a 20-year-old red-haired student at gunpoint and then strangled her to death. The final known murder occurred on 1 September 2015, when he raped and strangled a 37-year-old woman outside a house on Khrustaleva Street. ==Investigation and arrest==
