Karen Gilbert was 26 when she vanished after a night out in Quebec City on October 7, 2012. She was last seen leaving a bar on rue Saint-Jean and took a taxi toward the Montmorency Falls area; that drop-off is the last known contact. At the time she was described as 5 feet 5 inches, 141 pounds, with green eyes and long chestnut hair shaved on the sides, wearing a burgundy coat, a white vest or t-shirt, and blue jeans.

Authorities searched the banks of the Montmorency River and family and friends ran their own searches, but no significant evidence emerged. The family has considered possibilities ranging from an accidental fall to abduction, but nothing has been substantiated. There have been reported sightings outside Quebec, including one in Hawkesbury that was noted as confirmed, yet the case has grown cold and no concrete answers have been found.

If anyone saw Karen on the night of October 7, 2012, or has reliable information about her whereabouts afterward, please come forward.
