Oleg Ten

Oleg Ilarionovich Ten (; born 1 March 1975), known as The Policeman Maniac , is an Uzbekistani-born Russian serial killer and former policeman who abducted, killed and dismembered at least three women in Saint Petersburg from 2004 to 2005. Initially convicted for two murders and sentenced to life imprisonment, he confessed to a third murder in 2019, and since then authorities have been investigating possible links to other unsolved murders.

Early life Oleg Ilarionovich Ten was born in Tashkent, Uzbek SSR in 1975.

Unbeknownst to most, however, Ten also developed a gambling addiction and frequently visited local casinos. As he often lost the majority of his monthly salary to this, he resorted to working as a private taxi driver as a secondary job. He eventually decided to start stealing from potential customers, and would resort to killing them if necessary. On that day, he was driving around in his red GAZ-3110 when he spotted an 18-year-old university student hitching for a ride from the Pionerskaya Metro Station. He decided to pick her up, but for an unclear reason, the pair had an argument along the way. Upon reaching an isolated area of Sofia Kovalevskaya Street, Ten stopped the car and attacked the victim, eventually managing to pull her out of the car. After doing so, he pushed her to the ground, pulled out a knife and stabbed her 13 times in the head, chest and neck. Following the murder, Ten proceeded to mutilate her body and sever her left breast before leaving the body in a nearby yard. While driving around town after suffering another loss at a casino, he spotted 24-year-old accountant Natalya Kosenkova walking down the street. He noticed that she wore gold jewellery and, thinking he could sell it for money, decided to follow her to her apartment on Danube Avenue. A few minutes into the trip, however, he changed directions and drove to an isolated location, where he proceeded to attack his passenger. Using his knife, he stabbed her multiple times before ultimately slashing her throat and killing her. Afterwards, he stole whatever money she had on her as well as her mobile phone, which he decided to use for himself. Ten would later be detained and questioned by colleagues yet again but was released after he showed his police badge and ID.

Authorities have since started reinvestigating other cold cases in Saint Petersburg and the surrounding area, as they believe that Ten has likely killed or maimed others. He is currently being investigated for a series of murders committed in Pushkin during the early 2000s when several young women were killed near the Alexandrovskaya Metro Station—at the time, Ten was still at the police academy and constantly travelled home through this exact station.
