Maryse Chalette was 26 and living under a foster-care placement connected to the CHRDL regional hospital in Saint-Charles-Borromée when she left for a walk in the Joliette area at about 12:30 p.m. on November 22, 1971. She was wearing a long gray maxi-style coat and black plastic boots. After she walked away from the hospital area she was never seen again and there is no publicly documented trail after that midday outing.

Records list her as about 5 feet 4 inches tall and 115 pounds, a white female born in 1945 with brown hair and black eyes. An alternate surname spelling Cholette appears in the files. Official listings are inconsistent on one point: a descriptive paragraph once states a last-seen date of January 22, 1971, but the structured records and a 2023 Quebec National Assembly compilation record the disappearance as November 22, 1971. The Joliette MRC detachment of the Sûreté du Québec handles the investigation; the police reference number is 157-711122-019.

No publicly documented sightings, discoveries, suspects, arrests, or confirmed explanation for what happened after she left have been released. Does anyone have information about Maryse’s movements in Joliette on that November day or recall seeing a woman in a gray maxi coat around noon in 1971?
