On October 15, 1977, 17-year-old Jacques Chaput left his family home in Cap-de-la-Madeleine, Quebec, after an argument with his mother and has not been seen or heard from since. At the time he was described as 5 feet 10 inches, about 130 pounds, slender, with long brown hair, brown eyes and a previously fractured right wrist. He was last seen wearing a dark green sweater, a t-shirt and blue denim pants and left a note saying he planned to travel to another province.

Jacques lived in a French-speaking household in what is now part of Trois-Rivières. His family waited six months before filing a missing person report with police in 1978, believing at first that he had run away. His sister Louise remains especially affected by the uncertainty and the delay in reporting. The Trois-Rivières Police Department still lists the case as open, and groups including the Missing Children’s Network have produced age-progressed images to show how Jacques might look now.

No confirmed whereabouts or further concrete evidence about what happened after he left home have been reported. If anyone knew Jacques, his routines or where he might have traveled in autumn 1977, can you share information that might help the investigation?
