Janet Derbyshire was 29 when she was last seen on December 4, 1976, on St. Joseph Island, Ontario. Witnesses reported she jumped from the St. Joseph’s Island Bridge and was seen floating downstream about a quarter of a mile before submerging. A search and rescue effort followed but she was not found.

Authorities have long presumed she drowned in the cold, fast currents that day, but her body was never recovered and the disappearance remains unresolved. The island community still remembers the loss and the absence has left her family without a final resting place.

If anyone on or near St. Joseph Island at that time has information about the bridge, the river conditions, or sightings that day, please come forward.
