Anatoly Onoprienko, 'The Terminator', earned his nickname from an unprecedented spree of mass killings in Ukraine. In just 4 months he slaughtered 43 people, entering households and murdering whole families at a time. Children and even babies fell victim to this merciless killer. Onoprienko claimed he was on a dark mission for supernatural powers, that he heard voices in his head telling him to kill. But in reality he killed to make money: his arrogance and avarice led to his downfall as police found over 100 trophies stolen from victims stashed in his apartment. Onoprienko is sentenced for 52 murders, making him one of the most prolific and evil serial killers of the century.
