John Wayne Gacy
John Wayne Gacy was known as “The Killer Clown.” Gacy was arrested after being caught sexually assaulting two teenage boys in 1968, and was sentenced to 10 years in jail. But because he behaved behind bars, he was released after only 18 months, proving that the U.S. legal and criminal system was severely lacking at the time. Gacy became a popular member of his community as Pogo the Clown, and regularly visited children’s parties and events. Over the next six years, he would kidnap, rape, torture, and brutally murder 33 boys. He received the death penalty for his crimes in 1994.
