Pogo The Clown
John Wayne Gacy frequently dressed up as his alter ego, Pogo the Clown, at parties that he hosted for his the children in his neighborhood. But by 1978, Gacy became known as the killer clown — and American serial killer and rapist. He sexually assaulted, tortured and murdered at least 33 teenage boys and young men between 1972 and 1978 in Illinois. Gacy spent 14 years on death row before he was executed by lethal injection at Stateville Correctional Center on May 10, 1994.
