- John Wayne Gacy- "The Killer Clown" (March 17, 1942 - May 10, 1994) Gacy was an American serial killer. He was convicted and later executed for the rape and murder of 33 boys and young men, 28 of whom he buried in the crawl space under his house, between 1972 and his arrest in December 1978. He became notorious as the "Killer Clown" because of the many block parties he attended, entertaining children in a clown suit and makeup. As he confessed, he claimed he had first killed in January 1972. Most of the victims were young male prostitutes or teenage runaways. The youngest victim was nine years old. The oldest was around 20. During his time on Death Row, Gacy took up oil painting, and his favorite subject was painting portraits of clowns. On May 10, 1994, Gacy was executed at Stateville Penitentiary in Crest Hill, Illinois. Gacy's execution proved problematic when the chemicals used in the lethal injection were mixed in a way that caused them to solidify, and as a result, he reportedly took 27 minutes to die. His reported last words were "You can kiss my ass." Original Artwork & Artifacts For Sale (click image for larger picture): Currently Sold Out...
