Serial killer Dennis Rader, known as the BTK Killer, killed 10 people between 1974 and 1991, terrorizing residents of Wichita, Kan. During his killing spree, Rader sent letters to the police and media describing details of the killings. Then, just as suddenly as the murders began, they abruptly stopped.
In 2004, Dennis Rader resurfaced and resumed taunting police with letters. In one communication he modified an article written about the BTK serial killer case and sent it off to the media, along with proof that he was BTK. In 2005, 60-year-old Rader confessed to committing all 10 murders.
