John Wayne Gacy – Executed by Lethal Injection
John Wayne Gacy was one of those notorious criminals who outwardly looked like a friendly man dressed up as “Pogo the Clown” or “Patches the Clown” while entertaining young children at parties; however, beneath the genial mask lay a horrifying truth. He was convicted of killing 33 young men and boys; no wonder he came to be known as “The Killer Clown.”
Violation, torture, and murder were some of the charges labeled against him. Gacy was eventually arrested and used the insanity plea card in court, hoping to get a not-guilty verdict. However, it did not work, and Gacy was executed by lethal injection on May 10, 1994.
