The BTK Strangler

In 1974, a man identifying himself as the BTK (Bind, Torture, Kill) Strangler started a killing spree in Kansas spanning the next two decades. He managed to kill ten people while eluding an intense manhunt by police. After a 13-year lull, he reemerged in 2004 through a disturbing letter to the media, that ultimately lead to his capture a year later.
