Diane Bonneau, 33, disappeared from her home on Boulevard du Jardin in Saint-Félicien, Quebec, on June 19, 2012. She was last seen around noon and reportedly left on foot, leaving behind her purse, keys and other personal belongings — details her family says point away from a planned departure. She had a six-year-old son and was described by her mother, Jacqueline Dion, as cheerful, energetic and devoted to her child.

Authorities opened an investigation the evening her disappearance was reported. In the initial hours and days police, family members and volunteers conducted extensive ground searches in the woods between her home and the nearby Ashuapmushuan River, plus aerial and aquatic patrols; no trace of Diane was found. Diane’s partner reportedly took and passed a polygraph in the months after she vanished, and investigators later requested her dental records. Human remains found later in the Lac-Saint-Jean area have not been linked to Diane.

The investigation remains open and the family continues to push for searches in deep sections of the Ashuapmushuan River. If anyone in Saint-Félicien or nearby saw Diane around June 19, 2012, or has information about her movements that day, please come forward.
