John Wayne Gacy, "The Killer Clown" | Serial Killer Documentary

John Wayne Gacy was convicted of 33 murders of mostly teenage boys. He was sentenced to death for 12 of those murders (12 proved to have been committed after Illinois had passed post-Furman death penalty), and to natural life in prison for the others. The bodies of most of the victims were unearthed in the crawl space under Gacy's middle class home in the Chicago suburbs. Evidence showed that the defendant led a double life, engaging in charitable and political activities at the same time he was committing a series of sadistic torture murders. He enticed many young men to his home for homosexual liaisons, tying or handcuffing his partners then strangling or choking them. Gacy was a successful contractor, was active in the community, and often dressed up as a clown for parties. On December 11, 1978, a 15-year-old Des Plaines high school sophomore, Robert Piest, disappeared shortly after leaving work at a pharmacy where Gacy had recently completed a remodeling job. Police put Gacy under surveillance, and when it was learned that two teenage employees of Gacy, Gregory Godzik and John Butkovich, also had recently disappeared, the police obtained a search warrant for Gacy's home. A roll of film belonging to Piest was seized in the ensuing search. A second search warrant was executed and three lime-covered bodies were found in the crawl space. Gacy pointed officers to the precise locations of certain bodies in the crawl space and stated that he had lured the victims to his home, either expressly for sex or through the promise of employment, and then strangled them. A total of 29 bodies were recovered on the property and 4 more were discovered in a nearby river. Gacy recanted his confession and did not testify at trial, where he asserted an insanity defense unsuccessfully.
