Denis Beauchamp, 27, was last seen in Montreal on April 18, 1977. About 5 feet 3 inches tall and 50 kilograms, Denis had brown hair and brown eyes, was a transsexual who had breasts, and was known to dye their hair blond.

In the days before Denis vanished, emotional distress followed a dispute with a boyfriend; Denis stayed with a sister for a few days and left that home — the last confirmed contact with family. The investigation remains open but the trail has gone cold.

Does anyone who knew Denis or was in Montreal that April have information to share?
