Claude Houle was 32 when he disappeared from Saint-Grégoire, a sector of Bécancour, Quebec. He was last seen on June 3, 1976; a witness reported seeing someone fall from the Laviolette Bridge, which crosses the Saint Lawrence River between Trois-Rivières and Bécancour. That sighting is the last known trace of him.

At the time he vanished he was described as a Caucasian male, slender, 5 feet 10 inches and about 139 pounds, with blond wavy hair and green eyes. He was wearing a red plaid leather coat, a white vest, dark blue pants and black shoes. Extensive searches of the river and shoreline turned up no sign of him, and his body has never been recovered. The Sûreté du Québec led the investigation but has not been able to determine what happened.

Does anyone who lived near the Laviolette Bridge in June 1976, or who knew Claude, have memories or information that might help fill in the missing hours that day?
