Yep, no question about it regarding Gein. Just watched a documentary about Arthur Shawcross from NYC, who talked about his murders like he was telling what he had for lunch that day. Scary. As far as the killer clown, there's a really good book called The Last Victim by Jason Moss. He wrote to serial killers to write his dissertation about them, and ended up corresponding with Gacy frequently, as well as talking on the phone with him and visiting him in prison. It's a scary thing to see how manipulative Gacy was, and several years later Moss committed suicide. The poor guy got in way over his head, I guess. Thought he was using Gacy and Gacy was using him. I recommend the book if this sort of thing interests you!
