Alexis St-Denis, 19, vanished from Trois-Rivières, Quebec, in late autumn 2013. Authorities described him as about 6 feet 1 inch, 176 pounds, with short brown hair, brown eyes and prescription glasses. They also noted he may experience periods of deep distress.

A passerby later found Alexis’s cell phone, wallet and headphones on the Pont de Fer bridge over the Saint-Maurice River near Highway 40. Those personal effects were the only items recovered and no further sign of him has been reported. Police asked the public for information and the family continues to seek answers.

If anyone who knew Alexis or who was near the Pont de Fer bridge on or after November 2, 2013 has information, please share what you remember.
