Remi Engrand was 23 when he was last seen on May 19, 1998, in Salaberry-de-Valleyfield, Quebec. He had been staying for several days at a men’s residence and went for a walk with two other residents to Parc Delpha-Sauvé, a waterfront park where he reportedly wanted to swim near a waterfall. At some point the three men separated and, when the other two returned, Remi was gone.

The core facts remain a young man, a waterfront park, companions who briefly separated from him, clothing on the shore, and no confirmed sighting after that.

Did anyone who lived in or visited Salaberry-de-Valleyfield around May 1998 see Remi or notice anything unusual at Parc Delpha-Sauvé that day?
