Known as the "BTK Killer" which stands for "bind, torture, and kill"an unknown killer caused terror in Witchita, Kansas, area from the 1970's to the 1990's. No one knew who he was until 2005, he was finally caught and revealed to be Dennis Rader, a seemingly average married father of two. His first crime was in 1978. Later that year he began seeking fame for his killings, writing letters and reporting his crimes.



Rader was born in 1945 and grew up in Wichita along with three brothers, all of whom graduated from Heights High School in Wichita. Rader was in the Air Force in Viertnam from 1965 to 1969. Joseph Otero, BTK's victim, was also in the Air Force at the same time. He worked in the meat department for a Park City grocery store and then as an assembler at the Coleman camping gear firm between 1971 and 1973, where he met two of his earlier victims. Many referred to him as a kind of guy who wasn't very noticeable, one who never really stood out from others. It was his ability to "blend in" that allowed him to go undetected for so many years.

He broke into the homes of his victims and "bind, tortured, and killed" them. He murdered 10 people this way. He murdered entire families, basically whoever lived in the house or was unfortunately in the house at that time. His final crime was in 1991, but he resurfaced in 2004 and again sought media attention. This eventually led to his arrest. He pled guilty and was ordered to serve 10 life sentences in prison.
