Alfred Elmer Hoffman Marshal, known as Al, was 17 when he vanished from Fort Leonard Wood, Missouri, on the evening of October 9, 1976. He was last seen leaving the base at about 7:30 p.m. with 17-year-old Teresa Joanna Gossage; both were students at Waynesville High School and children of officers stationed at the base. Alfred is described as a White male, brown hair, green eyes, about 6 feet 1 inch and 160 pounds. He may have used Hoffman and Marshal together or separately as surnames.

The next day Alfred’s car was found locked and abandoned on a side road in an isolated area of Fort Leonard Wood. His jacket remained in the backseat and his hairbrush was in the console. Records state there was no evidence of foul play at the vehicle. Family members doubted a runaway theory: Alfred reportedly had about $1,000 in the bank and planned a hunting trip with his father, a Christmas trip to Germany, and college. Later murders at the base prompted investigators to consider possible links, but no evidence has tied those crimes to Alfred and Teresa.

The U.S. Army Criminal Investigation Command classifies Alfred as an endangered missing person and there is no recorded resolution. If anyone knew Alfred or Teresa, their movements that evening, or saw the car after October 9, what information can be shared with investigators?
