In this episode of Unfiltered Crime, we dissect the double life of Dennis Rader, the BTK killer—Bind, Torture, Kill. From the brutal slaughter of the Otero family to the chilling phone calls, taunting letters, and the infamous floppy disk that finally brought him down, we walk through three decades of terror in Wichita and the quiet church-going family man behind it all. This is a raw, detailed, no‑nonsense look at how a seemingly ordinary neighbor became one of America’s most methodical serial killers, and how he was finally unmasked after 30 years.
