On the evening of February 24, 1978, four mentally challenged men set off on a road trip fifty miles from their homes in the Yuba City, CA area to watch a college basketball game in Chico. Expected back only hours later, they never arrive. But soon their car is found abandoned on an isolated road high up in the Plumas National Forest, and before long the spring thaw will reveal their fate. Though one lingering question remains ... What happened to the Yuba County 5? Did they take a wrong turn and get lost? Or was it something much more sinister? Join host Ryan Kraus for a look inside the psychology of this enduring mystery.
