John Wayne Gacy, Jr. (March 17, 1942 – May 10, 1994; pronounced Gay-see), also known as The Killer Clown and Pogo the Clown, was an American serial killer and rapist. He is confirmed to have killed 33 young men and teenage boys. He killed them in a brutal way and buried their bodies in or near his Chicago home. Gacy did not use a gun for any of his crimes.
Gacy became known as "Pogo the Clown" and the "Killer Clown" because he would dress as a clown for fundraising events and parades. In March 1980, Gacy was convicted of 33 murders, as well as sex crimes, committed between 1972 and 1978, and given the death penalty. He was executed by lethal injection on May 10, 1994. Gacy's execution was filmed; his last words were, "kiss my ass". There were problems with the execution, but it eventually ended in Gacy's death. Immediately prior to his execution, Gacy observed the Last Rites with a Catholic priest; he had converted to the Catholic Church.
