Andree Thibault was 28 and described as quiet and independent when she was last seen on November 12, 1988, in Montreal’s Sainte-Marie district. There were no signs of a struggle, no torn-apart belongings, and no note to explain her disappearance; friends and family said she had no known enemies and no history of leaving without warning. Initial investigative work turned up few clues and the circumstances of the day she vanished remain unclear.

Investigators later followed a possible sighting of Andree in the Vancouver area, but that lead went cold. The file remains open with the Service de police de la Ville de Montréal and the RCMP, and age-progressed images have been circulated in hopes of generating information. Few new leads have emerged, leaving many unanswered questions about where she went and why.

If anyone knew Andree, saw her in late 1988, or has information about a possible sighting in Vancouver, please share what you know.
