John Wayne Gacy, Jr.
John Wayne Gacy, Jr. was born in Chicago, Illinois, in 1942, the second of three children. He was one of the most disgusting and gruesome serial killers you could find. He had a penchant for boys, and clowns. He was convicted and later executed for the rape and murder of 33 boys and young men between 1972 and his arrest in 1978, 27 of whom he buried in a crawl space under the floor of his house, while others were found in nearby rivers. He became notorious as the “Killer Clown” because of the many block parties he threw for his friends and neighbors, entertaining children in a clown suit and makeup, under the name of “Pogo the Clown”.
