On April 23, 1973, 22-year-old Guy Carignan and his friend, 21-year-old Lucie Gélinas, were seen in Trois-Rivières, Québec, setting out to hitchhike to Vancouver from the Couronne roundabout. Lucie’s father dropped them off that day; neither young person was seen or heard from again. Guy was described as a Caucasian male, brown hair, brown eyes, about five feet eight inches and 160 pounds. Lucie was a student at the University of Trois-Rivières.

Initial inquiries turned up no significant leads and the trail went cold, a situation complicated by their plan to hitchhike and the many possible routes and encounters that entailed. The disappearance remains open and unresolved; those who knew them or who have information about that trip are asked to come forward. What can anyone who remembers Trois-Rivières in April 1973 add about the Couronne roundabout or that day?
