A potential suspect fled the scene; however, police believe he was involved in a car accident in the neighbouring city, where he allegedly collided with another automobile in Saint-Jérôme, sustaining serious injuries.

He is in hospital, according to police, who will meet with him when his condition improves.

The other driver involved in the crash was also seriously injured, and is in stable condition.
