Milwaukee serial killer Jeffrey Dahmer is once again getting attention, thanks to creator Ryan Murphy's new Netflix series, DAHMER–Monster: The Jeffrey Dahmer Story. Evan Peters, best known for American Horror Story, plays Dahmer. To prepare for the role, Peters had to get into the mind of a serial killer.
