Lead #3Did anyone see Mark or his vehicle on the route between Kingman and San Francisco on or after November 26, 1985?
Mark Allen Weller, a 28-year-old man, disappeared on November 26, 1985, from Kingman, Arizona, after telling his mother he was traveling to San Francisco. His packed suitcase and prepared clothing suggest premeditated travel, yet he never arrived at his destination and never returned home despite his established pattern of calling his mother regularly. Over four decades later, the circumstances of his disappearance—whether voluntary departure, accident, or foul play—remain unknown, and investigators continue to seek information from anyone who may have encountered him or his vehicle.
