Sebastien Metivier was eight when he vanished from Hochelaga-Maisonneuve in Montreal on November 1, 1984. He and a 12-year-old friend, Wilton Lubin, had attended a hobby workshop in the basement of the Tres-Saint-Nom-de-Jesus church and were last seen together outside the church, a short walk from their homes. Sebastien was wearing a brown jacket, a blue and grey jogging suit with a patch on the right knee, and red Cougar-style boots. He had light brown hair, brown eyes, a pierced left ear, a small scar on his right cheek, and a birthmark on his lower abdomen.

Initial reports treated both boys as runaways after several alleged sightings, but Wilton’s body was recovered from the St. Lawrence River in early December 1984, shifting the case toward foul play. Another nearby child, four-year-old Maurice Viens, also disappeared the same day and was later found dead, prompting a large investigation that has examined suspects including a convicted sex offender who died by suicide in 1993 the day before a scheduled polygraph. Sebastien’s disappearance remains unsolved.

If anyone knew Sebastien, Wilton, or Maurice, or remembers that neighbourhood in 1984, what information can be shared to help bring answers?
