Wichita, KS., killer Dennis Rader
signed the taunting letters he sent to police "B.T.K," meaning "bind, torture, kill." Indeed, this was the means by which he murdered ten people between 1974 and 1991, all the while maintaining a life as a husband, father, church deacon and scout leader. His first four victims were all members of the same family, and were killed on the same day, in front of each other. Rader's undoing came in 2005, after police traced him using a floppy disk he sent them. On June 27, 2005, Rader pleaded guilty and described, in great detail, each murder. He is currently incarcerated at El Dorado Correctional Facility, where he is serving ten consecutive life terms.
