Dennis Rader is the infamous serial killer known as BTK (Bind, Torture, Kill). A new documentary on A&E tries to make sense out of how he became a psychopathic killer. Forensic psychologist Katherine Ramslend has been talking with Rader by phone for over ten years, trying to understand him. She says that every serial killer has a unique set of factors that turns them into monsters. She pointed to his chilhood, when he began to trap and torture kittens before killing them.
The daughter of Dennis Rader, the convicted murderer known as the BTK Killer, is speaking out about the harassment she has endured from her serial killer father and his supporters after she cut off ties with him. Kerri Rawson said she wants nothing to do with Rader, who was convicted of killing 10 people in Wichita and Park City, Kansas, over 17 years. Rawson said that after she cut contact with her father, he told his followers to harass her.
