In 2010, Gaidamachuk attempted to kill another elderly woman, who managed to escape. The victim reported to the police that she was attacked and the attacker was a 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 neighbour had seen her leave around the time of the murder. After the police received the information from Povaritsyna's neighbour, they arrested Gaidamachuk who quickly confessed to the killings. Another woman had been initially suspected of the crimes and, after pressure from authorities, had already 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. In February 2012, the court case began in Yekaterinburg. Gaidamachuk gave a confession to the indictment during the preliminary investigation but contested this throughout her trial. A forensic
psychiatric examination conducted by
GNTSSSP Serbsky showed that Gaidamachuk, although she showed some mental illness, was
legally sane at the time of the murders. In June 2012, Gaidamachuk was charged with 17 counts of murder and one count of
attempted murder, and was sentenced to 20 years in prison, the maximum possible sentence for women according to Russian law. Relatives of the victims were outraged at the short length of the sentence, citing that Gaidamachuk received only just over a year per killing, adding that she should never be freed. ==See also==
