Mary Louise was petite, about 5 feet 4 inches and 115 pounds, with short brown hair and brown eyes. The Service de police de la Ville de Montréal holds the file and the case remains open.

If anyone knew Mary Louise, saw her in Montréal around February 23, 1991, or has information that could help, please come forward.
