A new documentary on A&E is looking into how the BTK Killer, Dennis Rader, came to be a psychopathic serial murderer who went on a 17-year reign of terror in Witchita, Kansas.
“I lived a normal life, yet I had a real dark mind,”Rader speaks in the documentary.
Rader was reached by Katherine Ramslend, a forensic psychologist.
“I’ve been corresponding with Dennis Rader for over 10 years to try to understand what led him to become one of the most notorious serial killers in America,”Ramslend stated. “Each serial killer has a unique set of factors that turns him or her into monsters.”
Ramslend points to Rader’s childhood, when he showed signs of sadistic behavior and began to trap and torture kittens — early signs that forecast his depraved future .
Rader, now 76, is currently serving 10 consecutive life sentences.
