Below is the answer to this week’s True Crime Trivia: (C) John Wayne Gacy is the answer to this one. Unfortunately, he was an American serial killer with at least 33 victims. Gacy regularly performed at children's hospitals and charitable events as "Pogo the Clown" or "Patches the Clown" –personas he had concocted. He became known as the Killer Clown due to his public services as a clown prior to the discovery of his crimes. Clowns can be scary enough, but you add the likes of Gacy & fictional characters like Pennywise and forget about a clown party anytime soon.
Gacy was sentenced to death in 1980 and was executed by lethal injection at Stateville Correctional Center in Illinois on May 10, 1994.
