Jean Rene Duguay, 21, vanished from Montreal on December 4, 1999. He was last seen that afternoon on the Lachapelle Bridge over the Rivière des Prairies in the company of a friend. Official reports from that day indicate he may have entered the water, but the precise sequence of events on the bridge has not been made public.

At the time he disappeared he was 6 feet 2 inches tall, weighed 91 kilograms, and had brown hair. Searches and the initial investigation did not produce conclusive results, and the case went cold, leaving his family without closure.

Does anyone who was in the Lachapelle Bridge area on December 4, 1999, or who knew Jean Rene, have information that could help clarify what happened that afternoon?
