Andrei Chikatilo

Andrei Chikatilo was a Soviet serial killer who killed at least 52 women and children from 1978-1990. In the process of trying to catch him, Soviet police solved more than 1000 unrelated crimes, including 95 murders and 245 rapes. The first time he was captured he was released from custody because his semen type was different from his blood type, which is extremely rare. He even helped police with the investigation at that point. When he was executed, he exclaimed “Don’t blow my brains out! The Japanese want to buy them!”
