The BTK Killer - Dennis Rader

Dennis Rader was born in Pittsburg, Kansas, on March 9, 1945, and grew up in Wichita. He was the oldest of four sons and had a relatively typical childhood, despite odd behavior such as hanging stray animals, according to reports.

In the mid-1960s, Rader dropped out of college and joined the United States Air Force. After returning to Wichita in 1971, he married Paula and worked for a year for an outdoor-supply firm. He started working for ADT Security Services in 1974 and stayed for a long time.

Rader led a double life: by day, he was a dedicated family and business man, but by night, he tormented the Wichita, Kansas, area as the "BTK killer" committing 10 murders and engaging in brazen communications with authorities between 1974 and 1991.

In 2004, Rader's alter identity reappeared, but his proclivity for leaving clues led to his capture and life sentence the following year. On February 25, 2005, Rader was arrested and charged with ten counts of first-degree murder. His neighbors and church members were taken aback by the news, unwilling to believe that the guy they knew was the serial killer who had terrorized the neighborhood for so long
