John Wayne Gacy is known as "The Killer Clown" for his hobby of painting clowns and performing at birthday parties as Pogo the Clown. Gacy is believed to have lured as many as 33 teenage boys and young men into his suburban Illinois home in the 1970s. With his clueless wife in the other room, he sexually assaulted them, strangled them to death, and buried their bodies in the crawl space under his house before he was caught and finally executed in 1994.
