Bind Torture, and Kill
Bodycount: 10
Dennis Raider was active as a serial killer for over 30 years before capture.
He was a Boy Scout leader who actually left a meeting to kill the church deacon, and returned to the meeting as though nothing had happened. On their campouts he would go far into the woods late at night, lay himself in a grave, and tie himself up to perform autoerotic asphyxiation acts while his camera took photos. There was one incident where he couldn't untie himself by morning, and his troop had to free him.
