The 10 hardest serial killers of all time

Dennis Rader

Dennis Rader, the infamous American serial killer, gave himself the nickname BKT (Blind, Kill, Torture), and committed heinous crimes between 1974 and 1991 killing 10 people in cold blood, mostly women from Kansas City. He would write letters to the police putting down lurid details of the murders he committed and scoff at their effort to hunt him down. In 2004, US police finally got their hand on him. He got a lifer. As a child, Dennis Rader is said to have derived pleasure from torturing animals. He had a fetish for women’s underpants, too. Later, he took to killing women, peeling off their underpants and wearing them.
