Dean Martin was 18 when he was last seen at a cottage on Mount Carleton in Carleton-sur-Mer, Québec, on May 25, 1983. Witnesses say he walked away from the cottage that day without telling anyone where he was going and left no note; there were no signs of distress in the moments before he disappeared. At the time he was described as 5 feet 11 inches, about 154 pounds, with brown eyes and hair reported as brown or blond. He was last seen wearing a red plaid jacket, blue jeans, and Kodiak brand boots.

The investigation was handled by the Avignon and Bonaventure MRC SQ and early searches produced no clear leads. Public details about who else was at the cottage or the events that day are sparse, and the rugged, sparsely populated terrain around Mount Carleton has complicated efforts to find traces of his whereabouts. The lack of subsequent contact or signs of foul play has left the case cold and Dean’s family without closure.

If anyone was in the Mount Carleton area around May 25, 1983, or has information about Dean’s movements that day, please come forward.
