Marthe Turcotte was 19 and a nursing student at Thetford CEGEP when she disappeared after being dropped off at Jean-Talon metro station in Montreal on Monday, September 13, 1971. Her sister gave her the ride to the station; that is the last confirmed sighting. She was described as a Caucasian woman with brown hair, brown eyes and wearing eyeglasses.

The Service de police de la Ville de Montréal has handled the investigation, which remains open. Few public details or credible leads have emerged, and there are no known witnesses, suspects or a clear motive reported. The circumstances of what happened after she entered the busy metro station are unresolved.

Did anyone in Montreal in September 1971 see or remember Marthe at Jean-Talon or in the surrounding area?
