Andrei Chikatilo, also known as the Butcher of Rostov and the Rostov Ripper, was one of the most notorious serial killers in the Soviet Union, maybe even the most prolific in modern history.
The monster had an appetite for murder and human flesh. He was a child molester who enjoyed mutilating and eating his victims. When arrested, policemen noted a disturbing odor emitting from the pores of his skin, which was caused by the rotten human flesh in his digestion.
