Andrei Chikatilo confessed to 56 murders when he was eventually caught in 1990. The brutal killer preyed on children and young vagrants, eating intimate parts of their bodies. On 22nd December 1978, Chikatilo killed his first documented victim; 9 year old Lena Zakotnova was lured into an abandoned shed, where Chikatilo tried to rape her. Trying to control the struggling child, Chikatilo slashed her with a knife, ejaculating whilst doing so, confirming his psychological connection between violent death and sexual gratification that went on to typify all future attacks. An eyewitness had seen Chikatilo with the victim, shortly before her disappearance, but his wife provided him with a cast-iron alibi that enabled him to evade any further police attention. A 25-year old, Alexsandr Kravchenko, with a previous rape conviction, was arrested and confessed to the crime under duress, probably as a result of extensive and brutal interrogation. He was tried for the killing of Lena Zakotnova, and executed in 1984.
