3. Albert Fish
A cannibal serial killer who only considers children as his victims, Albert Fish, one of the American cannibal serial killers from our list, is truly one of the worse people I have ever heard about. He was also a child rapist, and would often claim that he’d had a child in every state in the US. However, it is not certain how true that statement was. It is certainly true that he engaged in rape, murder, and cannibalization of his victims, and while the exact number isn’t known, it is between three and nine. He met his end in the electric chair after being convicted of two murders.
