Born in 1945 in Pittsburg, Kansas, Dennis Rader went on to live a double life: Devoted family and company man by day, he also terrorized the Wichita, Kansas, area as the "BTK killer"—for "bind, torture, kill"—with 10 murders and brazen correspondence with authorities between 1974 and 1991. Rader's alter ego resurfaced in 2004, but his penchant for leaving clues led to his arrest and life imprisonment the following year.
