How does a decorated Army helicopter pilot and father of five become one of Washington State’s most prolific serial killers? Robert Lee Yates was the ultimate "wolf in sheep’s clothing." While his colleagues saw a disciplined soldier and his neighbors saw a devoted family man, Yates was stalking the streets of Spokane, leaving a trail of bodies in his wake. In this episode, we peel back the layers of his double life—from his early crimes in 1975 to the "grocery bag" signature that eventually led to his downfall. We explore the chilling reality of how evil can hide in plain sight, earning medals by day and committing atrocities by night.
