Alerte Quebec: scene and timeline
Emergency services were called to Autoroute 30 at kilometre 82 after a vehicle traveling the wrong way struck another vehicle in a frontal collision at approximately 8: 30 p. m. ET. The Sûreté du Québec located Diane Dupont Desrosiers at the scene and transported her to a hospital. A Silver alert had been triggered at 9: 00 p. m. ET to locate her after she was reported missing the previous evening in Saint-Eustache, and the Service de police de la Ville de Saint-Eustache confirmed she was found alive within 30 minutes of that alert being launched.
Immediate reactions
Louis-Philippe Ruel, spokesperson for the Sûreté du Québec, said, “We do not fear for her life. ” The Service de police de la Ville de Saint-Eustache confirmed the woman, who had been reported missing, was located alive by provincial police following the collision. Local emergency crews secured the scene and arranged medical transport for the injured parties.
Context and next steps
The woman had last been seen in Saint-Eustache around 5: 00 p. m. ET on March 20, 2026. A Silver alert is used to speed the location of missing persons who suffer from cognitive impairments; authorities invoked that procedure to mobilize resources quickly after the disappearance was reported.
Investigators will examine the circumstances that led to the vehicle entering the highway the wrong way and will determine whether the collision is linked to the disappearance report. Officials say medical updates and details about the collision investigation will be released as they become available, and the ongoing coordination between the Service de police de la Ville de Saint-Eustache and the Sûreté du Québec remains active. The alerte quebec notification that accompanied the search has ended with the woman now located, and authorities are expected to provide further statements on next steps and any charges as inquiries continue.
