Marie Berthe Perreault Astle Wiseman, 57, disappeared from her Pointe-Claire, Quebec home in the late spring of 1976, last seen around June 25 or 26. The exact date is unclear. Neighbors and family describe a domestic scene left intact: bags of groceries on the kitchen counter and no sign of forced entry, struggle, or disturbance.

Those details have made the disappearance especially puzzling. It appears she had either just returned from an errand or was engaged in an everyday task when she left the house and never came back. Investigators and family have repeatedly noted the absence of forensic clues or an apparent motive.

The case remains unresolved and has left the family without answers. Does anyone who lived in Pointe-Claire in 1976 or knew Marie Berthe remember unusual activity, visitors that week, or any detail that could help explain her sudden disappearance?
