When cannibalistic serial killer Jeffrey Dahmer was arrested, remnants of dead bodies were found in his kitchen: a head in the fridge, hands and genitals in cooking pots, more body parts in a freezer, and three male torsos in a 57-gallon drum. To turn victims into zombie sex slaves, he'd injected hydrochloric acid into their brains (it didn't work). Handsome and intelligent, Dahmer came from a good family, had been to college, was an Army veteran, and was liked by neighbors, who called him "the nice, quiet, good-looking white guy"—even though a foul smell came from his apartment. How did such a man become a cannibal and a murderer?
