John Wayne Gacy

John Wayne Gacy was a serial killer who raped, tortured, and murdered at least 33 young men and boys in the 1970s. He became known as the Killer Clown because he used to perform at children's hospitals and charitable events as "Pogo the Clown". Years before committing these murders, he used to work at a mortuary in Las Vegas. While being employed there, Gacy once slept in a coffin with a dead teenage boy but grew frightened and jumped out. He then travelled back to Illinois after the incident. He claimed that his first victim was a male acquaintance whom he saw in his room holding a knife over him when he woke up from sleep. Gacy said his involuntary orgasm from the murder was the "ultimate thrill" he had ever experienced.
