For decades, the BTK killer “Bind, Torture, Kill” taunted Wichita authorities with letters describing his crimes. He vanished for years, then re-emerged in the early 2000s with a new question: could police trace him through a computer disk and email? He thought the answer was no.

In this episode of Text Me When You’re Dead, we take you inside the cat-and-mouse game between BTK and investigators — a game that ended when metadata from a single church computer pointed straight to Dennis Rader. Discover how old-school forensics met new-school digital tracking, and how a serial killer’s arrogance finally led to his capture.

If you’re fascinated by true crime, cyber evidence, and the moment technology changed detective work forever, this is the story that defined the digital era of policing.
