Oleg Wirth

At this trial, Oleg shouted that Tatyana was not to blame, that the investigators had framed him and he hadn't been allowed to speak to a lawyer. Nevertheless, he was found guilty, convicted and sentenced to life imprisonment. When reading out the verdict, the presiding judge noted that Wirth was characterized by police as "an immoral, quick-tempered and prone to illegal activities" type of character. Kuzntestova, who was visibly depressed at trial, received 13 years imprisonment due to her cooperation, and after release, will not be allowed to move away and must report to law enforcement agencies twice a month. Wirth was transferred to a special regime colony, where he remains to this day. He appealed his sentence to the Supreme Court of Russia, but the verdict was upheld on October 8, 2014, effectively finalising his sentence.

On New Year's Eve in 2011, Wirth and three friends (two men and a woman) were drinking alcohol at his house. After passing out for some time, upon waking up, Oleg found that his lighter, a keepsake gifted by his deceased son, was missing. Suspecting that one of his companions had stolen the item, he took out a chisel and killed the man, hitting him several times on the head and chest. The two other guests were awoken by the noise, and, in an unsuccessful attempt to calm down the enraged man, were subsequently killed as well. At first, Oleg threw the bodies into the cellar, but then changed his mind and took out into the yard, where he covered them with snow and some garbage. In March of the following year, he dug out the remains and reburied them in the cellar.

Oleg Alexandrovich Wirth (Russian: Олег Александрович Вирт; born 1967) is a Russian serial killer who murdered five acquaintances in his home village of Urusha, two with the help of his girlfriend Tatyana Kuznetsova, between 2011 and 2012. After the former exposed his crimes to the police, he admitted his guilt, was convicted and sentenced to life imprisonment in a special regime colony.

Oleg Wirth was born in 1967 in Urusha, but records of his upbringings are scarce. He was known as a friendly man who worked as the head of the local housing and communal services department, was married and had an adult son. However, tragedy struck when his son was killed in an accident, and as a result, Oleg began to drink heavily and commit crimes. He was incarcerated for several offenses, including for rape. After serving out his sentence, he returned to Urusha, where he hooked up with 39-year-old Tatyana Kuznetsova, a jobless mother of three who had lost her parental rights due to alcoholism and hooliganistic behavior. The two lived in a small house on the outskirts of the village, and despite their previous convictions, both were well-regarded by fellow villagers.
