Over a two decade reign of terror, Dennis Rader stalked, raped and murdered his victims before boasting of his kills in encrypted messages to police and media.

Rader’s need for notoriety eventually led to his arrest and conviction for 10 murders in the Wichita area when investigators traced a floppy disk he had sent to a Kansas TV station to a computer at his church in 2005.
