10. The One with Ol’ Bumblebutt Ed Kemper

Pull up a chair, this one may take awhile. Ed Kemper loves talking about himself like Kanye loves Kanye, and that’s part of why he’s McKenzie’s favorite serial killer. Part bumbling and socially moronic giant, part genius killer, this guy is truly one of the worst of the worst and that’s why he’s opening our Mindhunter series (also because he appears first and we love chronology). Hold onto your heads, kids - seriously, hold onto your heads- because this one is going to be graphic.
