Around 7 p.m. on April 30, 1989, Mathieu Beauregard told his wife he was going to visit a friend and drove off in her car. Her cellphone was also in her car at the time. 

At 10:30 that night, the car Mathieu was driving was found on fire on Rang du Haut-de-la-Rivière near the military base in Farnham. Mathieu was not inside and has never been seen again.
