Btk mail

You're referring to the infamous "BTK" (Bind, Torture, Kill) serial killer, Dennis Rader, who sent letters and cryptic messages to the police and media during his killing spree in the 1970s and 1980s.

The BTK killer, also known as the "BTK Strangler," murdered 10 people in Kansas between 1974 and 1991. He would bind, torture, and kill his victims, often leaving behind cryptic messages and clues.

Rader, a married father of two, worked as an administrator for the Church of the Lutheran Brethren and was a Cub Scout leader. He was able to evade detection for over 30 years, despite the intense media scrutiny and investigation.

In 2005, Rader began sending emails and letters to the police and media, taunting them with his crimes and claiming to be the BTK killer. He eventually turned himself in in 2005 and was arrested, convicted, and sentenced to 10 consecutive life terms in prison.

The BTK case is considered one of the most infamous serial killer cases in American history, and it has been the subject of numerous books, documentaries, and films.
