John Wayne Gacy (March 17, 1942 – May 10, 1994) was an American serial killer and sex offender who raped, tortured and murdered at least thirty-three young men and boys in Norwood Park Township, Illinois, a suburb of Chicago. He became known as the "Killer Clown" due to his public performances as a clown prior to the discovery of his crimes. Gacy committed all of his known murders inside his ranch-style house. Typically, he would lure a victim to his home and dupe them into donning handcuffs on the pretext of demonstrating a magic trick.
