Quebec's independent investigations bureau is investigating a fatal car accident early Monday.
According to preliminary information provided to the BEI, at around 3:00 A.M. Sûreté du Québec officers noticed a vehicle speeding on Highway 30 near Highway 930.
The officers tried to pull the driver over, but said he shut off his headlights and took off.
After a short, one minute chase, the silver Hyundai hit a cement barrier near kilometre 58 in Candiac.
The passenger, a 20-year-old man, was pronounced dead at the scene. The driver, also 20, was taken to hospital in a critical condition.
Nine BEI investigators were sent to the scene to determine the exact circumstances that led to the fatal crash.
