For more than three decades, the name BTK haunted Wichita, Kansas. Between 1974 and 1991, ten people were murdered in a series of crimes that would remain unsolved for years. Then, in 2004,…
after more than a decade of silence, BTK suddenly returned. Letters began arriving. Messages were sent. The killer wanted to communicate again. But this time, the world had changed. Technology had changed. And the investigators were ready. What followed was one of the most remarkable investigations in American criminal history — an investigation that eventually led police to Dennis Rader. In this episode of The Global Casebook, I follow the case from its beginning in 1974, through the years of fear and uncertainty, to BTK's return, the digital clue that changed everything, the arrest of Dennis Rader, and the courtroom confession that finally closed the case. This is the story of the BTK killer. And the mistake that finally exposed him.
