The original "Killer Clown," Gacy is widely thought to be the inspiration for the terrifying and nightmare inducing Stephen King character, Pennywise the Clown. Gacy's death count totals 33 young men and teen boys, most of whom he buried in the crawl space under his home. An active member of his community, Gacy often dressed up as a clown to perform for charitable events and parties. He'd lure his victims to his house with the promise of giving them alcohol. After they were drunk, he would handcuff them then viciously torture and sodomize them before ultimately strangling them to death. In May of 1994, he was executed by lethal injection.
