Joseph Cohen was 28 when he vanished from Montreal in the summer of 1979. Friends last saw him the evening of Saturday, August 4, 1979, at the Blanche-Neige restaurant in the Côte-des-Neiges neighborhood. He is described as having black hair and green eyes, about 5 feet 3 inches tall and 141 pounds, and was wearing Adidas shoes that night.

His vehicle was later found abandoned in a parking lot opposite Valois Street. The Service de police de la Ville de Montréal lists his disappearance date as August 8, 1979, a few days after the last confirmed sighting. No explanation has been given for why his car was left there or for his sudden absence, and the case remains unsolved.

If anyone knew Joseph, saw him after August 4, 1979, or has information about the car left near Valois Street, please come forward.
