I always found Gacy to be one of the most interesting serial killers. The whole situation plays out almost like a carefully scripted Hollywood movie. He discovers his love for killing after he wakes up to find a runaway he let sleep at his house for the night standing in his doorway holding a kitchen knife. Gacy thinks the boy is about to hurt him, so they struggle and the boy dies. The boy was actually making breakfast for him and was trying to wake Gacy to eat. Gacy says this moment is when he discovers "the thrill of murder". Then he goes on for years killing over 30 people, all the while running a successful business, having friends and family, and being in the public eye. He was married, divorced, got engaged with another woman, separated with her, and then started dating his ex again... all while murdering young boys regularly. Unlike a lot of serial killers, this guy lived an incredibly normal life on the outside. Then we get in to the gross incompetence of the local police department at the time. Keep in mind.. before any of this, Gacy was already a convicted sexual predator and served time for assaulting a 15 year old boy... Two boys directly related to Gacy's business go missing. Another goes missing with Gacy being one of the last to see him. Gacy has his damn car.. and the cops see nothing fishy happening. Another boy goes to the police after being released by Gacy, tells the cops about being sodomized and tortured... and Gacy somehow convinces them that it was all consensual "slave play"..... I mean, holy shit these cops were bad... And then we have Gacy's odd fixation with the number of murders he wanted to be responsible for. He admitted on several occasions that he lost track of the actual number, but for some reason he wanted the total to be somewhere around 30-33 people. Read a few first-hand accounts of the situation and a number of the people involved talked about how cooperative he was with the police in finding the bodies until they reached 32. Then he began to insist that they had found them all and that there was no reason to keep searching. Even becoming upset and angered that they continued the search (they found 3 addition bodies after that, I believe). So now we have the mystery of what was the number he wanted to reach and what was the significance of it? He never mentioned it otherwise. Finally, we have his last words just before execution... "Kiss my ass". I mean.. can you even write a better script than that?
