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 them 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. On 30 June, Wirth and Kuznetsova were again out drinking in the company of a mutual friend. Not long after, the man stole a bottle of alcohol, which had been purchased with Oleg's money. After an argument arose between the two, Wirth took out a knife and stabbed his friend, and instructed Tatyana to do the same, which she did. After making sure that he was dead, the two criminals disposed of the body in the cellar. The next day, Wirth and Kuznetsova were out drinking with another friend, this time in the forest on the outskirts of the village. At some point, the friend started asking questions about the man, who had suddenly vanished two days prior. Fearing that he might get suspicious and report to the police, the duo killed him and hid the body in the bushes. ==Arrest, trial and sentence==
