John Wayne Gacy has gone down in history as one of America's most notorious serial killers. Dubbed the 'Clown Killer', Gacy brutally tortured, raped, and murdered 33 young men and boys in the 1970s.
Gacy did not see his victims as people, he even admitted to his lawyers that, to him, his victims were "not human beings". And this attitude continued right to the end.
He was executed on May 10, 1994 at Stateville Correctional Center in Crest Hill, Illinois, by lethal injection for the murders committed between 1972 and 1978. His last words showed the cold-blooded killer had no remorse, as he left the world saying simply: "Kiss my a**."
