For more than 30 years, serial killer Dennis Rader struck fear into the hearts of the people of Wichita, KS, by committing 10 brutal murders. Rader - who called himself the BTK Killer because he liked to bind, torture, and kill his victims - lived a double-life, hiding in plain sight with the help of his wife and two children who were completely unaware of his crimes. He is considered one of the most prolific American serial killers of all time.
After getting away with murder for more than three decades, Rader finally got caught because he got sloppy. Why? Because he loved bragging to the media through letters and graphic photographs, taunting police and others that they would never find him. If murdering wasn't twisted enough, there was a collection of disturbing images and drawings created by the BTK Killer.
