Duwane Roy Dreher, 33, was last seen November 7, 1955, in Mason City, Iowa. He visited his father that evening around 7:30 p.m.; the next day there were unconfirmed sightings of him walking north on South Federal Avenue saying he was heading to Chicago. His maroon 1950 Hudson was found near Willow Creek on November 10 with a parking ticket dated November 8. All his belongings were inside the car, but Dreher himself was gone.

Authorities searched the nearby river by dragging it but found nothing. Dreher, a U.S. Navy veteran who had returned to Mason City after World War II, never accessed his Social Security, veteran’s benefits, or bank accounts after his disappearance, which has fueled long-standing suspicions of foul play. Rumors over the years have suggested gambling disputes or romantic problems, but no solid leads have emerged and the case remains open and classified as endangered missing.

If anyone knew Duwane, his routines, associates, or where he may have been heading in November 1955, can you share information with investigators?
