Donald Joseph Mohrbacher, 42, vanished after leaving his Hinckley, Minnesota, home on June 19, 1967. He planned to drive about 100 miles to the Twin Cities for a painting job and expected to stay with his father, returning by June 21. He never arrived and has not been heard from since.

Mohrbacher was driving a black 1939 Ford pickup and was last seen wearing a light blue fishing hat, a Father’s Day gift from his children. He was carrying a penknife and a black wallet. He left behind his wife and seven children, the youngest just four months old at the time. His Social Security number has not been used since his disappearance and he is classified as an endangered missing person.

No significant clues have been reported and the case remains unsolved. Can anyone who knew Donald, his routes between Hinckley and the Twin Cities, or who remembers seeing that pickup in June 1967 come forward with information?
