What is this episode about?

The episode "BTK Part 3: The Final Mistake" from Post Mortem: CBS News' 48 Hours Podcast Companion covers the closing chapter of the BTK case, focusing on the decision that ended more than thirty years of evading capture. Listener discretion is advised, as the episode discusses torture, murder, and bondage. In this final installment, Dennis Rader returns to the spotlight, taunting investigators once again, and unknowingly hands law enforcement the evidence they need to identify him. The episode frames his downfall around a single, devastating lesson: ego can be fatal.
