The Freeze Plug Pulled by Hand - Episode 20

The Freeze Plug Pulled by Hand: The Disappearance of Sarah Boyd, Kimberly Boyd, and Linda McCord.

A blue Lincoln stalled on a dark highway because a freeze plug popped out of the engine, yet the temperature was nowhere near freezing. The car was found twenty minutes in the wrong direction, and a husband arrived home at dawn with mud-caked boots before reporting anyone missing. How does a reliable mother vanish along with her toddler and best friend without a single scream?

In this episode, we explore a credit card used to buy luggage three years after the disappearance, a witness who saw a beat-up blue vehicle stalking the women, and a police lieutenant who helped move the crime scene before it could be processed. Why did a confession years later mention "two birds" when three people were taken? The mechanical evidence suggests this breakdown was no accident.
