JOHN WAYNE GACY
Little John doesn’t look very happy in this photo he doesn’t look like a killer either. Turns out he had an abusive father who was alcoholic and was not too encouraging either, he constantly belittled him and probably affected his self-esteem. John Wayne Gacy is known to have killed 30 young men by strangulation. He was also taunted as a child by bullies. This, plus his failing health is thought to have affected him mentally causing him to commit those murders in a calculative and remorseless manner. He was known as the killer clown because of his job as a clown. He spent the next fourteen years awaiting execution and was later killed via lethal injection.
