The Iceman Trailer (it looks interesting, but I don't like how the film seems to make a mass serial killer appear like a tortured hero. Not quite sure what to make of it all).
The Real Iceman. First learned about him in my Abnormal Psychology class in college. He personally killed over 100 people in 30 years, although some estimate that the true number may be closer to over 200. You never want to insult a true sociopath.
