Alexander Pichushkin
Pichushkin targeted primarily elderly homeless men by luring them with the offer of free vodka. After drinking with them, he would kill them with repeated blows to the head with a hammer. In what became his trademark, or signature, he would then push a vodka bottle into the gaping wound in their skulls. He also targeted younger men, children and women. He would always attack from behind in order to take the victim by surprise and to avoid spilling blood on his clothes. He claimed that while killing people he felt like God as he decided whether his victims should live or die. "In all cases I killed for only one reason. I killed in order to live, because when you kill, you want to live," he once said. "For me, life without murder is like life without food for you. I felt like the father of all these people, since it was me who opened the door for them to another world." Experts at the Serbsky Institute, Russia's main psychiatric clinic, have found Pichushkin sane, but suffering from antisocial personality disorder and narcissistic personality disorder .
