Glen Allen Walls was 17 and a U.S. Air Force airman when he was reported missing on November 8, 1972, after failing to appear for duty at Malmstrom Air Force Base in Montana. He was last seen on October 10, 1972. Walls is described as a white male, 5 feet 11 inches, about 143 pounds, with brown hair and a scar over his right eye; his eye color is recorded either as brown or as one brown eye and one gray eye.

Investigators believed Walls may have left the base voluntarily and might have been with 19-year-old airman Steven W. Barnhill. The two had told others they planned to go on a trip but did not specify a destination. Possible places mentioned were the Highwood Mountains, Kings Hill, the Holter Dam, or Canada. Walls may have been driving a tan 1966 Volkswagen with Montana plate 2-57963.

The Air Force Office of Special Investigations has been unable to locate him and the case remains an active missing persons investigation. If anyone knew Glen Walls, Barnhill, the described vehicle, or their travel plans in October 1972, can you share what you remember?
