For nearly three decades, a mild-mannered church president and compliance officer lived a double life as one of America's most calculated predators — and the only thing that finally unravelled him was his own desperate need for attention. Dennis Rader, infamously known as the BTK Killer, taunted police and media for years before a single floppy disk ended his reign of terror, making his story one of the most chilling in true crime podcast history.

In this episode of Dark Whispers: Serial Killers, Dark Whisper Studios takes you deep inside the psychology of a man who bound, tortured, and killed ten victims across Wichita, Kansas between 1974 and 1991, then vanished into suburban anonymity for over a decade. We examine the FBI profiling techniques that kept the case alive, the taunting letters and packages BTK sent to police and journalists, and the catastrophic mistake — a metadata trail on a church floppy disk — that led investigators straight to his door in 2005.
