Marcel Pelissier, 28, disappeared from Boisbriand, Quebec, after leaving his home on the morning of May 13, 1980. At about 5:30 a.m. he drove off in a rented car with his Doberman pinscher, Hans, and was last known to be headed toward St. Jovite in the Laurentian Mountains. That departure was the last time family heard from him.

His sibling did not report him missing until July 29, 1980, more than two months after he vanished. Early inquiries indicated Marcel was involved in narcotics, a detail investigators considered but which has not produced definitive leads. The Sûreté du Québec holds the case file, and despite investigations the trail went cold.

The reasons for his leaving and what happened after he drove away remain unresolved. Did anyone in Boisbriand or St. Jovite in May 1980 see Marcel, the rented car, or his dog Hans?
