Three people were transported to hospital following an early morning rollover in the city's southeast.

At about 3:00 a.m., emergency crews responded to Blackfoot Trail, near 43 Avenue Southeast, following reports of an overturned vehicle.

On arrival, a man and a woman were located in the wreckage of a 2002 Infiniti I35 and a male passenger was found nearby. According to the police, the male passenger had been ejected from the rear seat of the car. 

The injured man, believed to be in his twenties, was transported to hospital by ambulance in critical, life-threatening condition.

The driver was transported to hospital in serious conditon while the passenger in the front seat suffered minor injuries.

An investigation conducted by the CPS Traffic Unit determined the driver lost control of the southbound vehicle and struck the centre median. The impact of the collision sent the car into the air.  The car landed on its roof, flipped back onto its wheels,  and travelled roughly 40 metres before coming to a stop in a grassy area.

Speed and alcohol are believed to have contributed to the crash.

The northbound lanes of Blackfoot Trail, between 46 and 53 Avenue S.E., were closed throughout the morning commute, but reopened shortly before 9:00 a.m.

Anyone who witnessed the crash or the gold coloured 2002 Infiniti I35 prior to the crash is asked to call the CPS Traffic Section, 403-567-4000, or Crime Stoppers.
