Irina Gaidamachuk
In 2010 Gaidamachuk attempted to kill another elderly woman, who managed to escape. The potential victim reported to the police that the killer had just attacked her and that they were female, which proved to be a vital clue as the police had assumed the killer was male. Gaidamachuk killed her final victim, Alexandra Povaritsyna, whose neighbor had seen her leave around the time of the murder. After the police received the information from Povaritsyna's neighbor, they arrested Gaidamachuk who quickly confessed to the killings. Another woman who had been initially suspected for the crimes, and after pressure from authorities, confessed to the murders. Gaidamachuk stated that she committed the murder-robberies to pay for vodka to feed her alcohol addiction, as her husband refused to give her money for it.
