On February 24, 1978, five men from Marysville California drove to a basketball game in Chico. The last time they were seen alive was shortly after the game ended at a convenience store just off the Chico State campus. Their car was later found in a remote area of the Plumas County forest. Months later, four of their bodies were found miles from the car.

To this day, the fifth man, Gary Matthias has not been found. The reason they ended up in the Plumas National Forest is still unknown, and has since become one of the strangest missing person's mysteries of all time.
