Seeking dashcam footage in serious collision investigation

We are investigating a single-vehicle collision that occurred earlier this month and are asking the public for help determining the vehicle’s movements before the collision.

At approximately 12:05 a.m. on Saturday, Sept. 5, 2026, a blue Subaru WRX was travelling north on Deerfoot Trail, approaching an unrelated collision scene that had temporarily closed the road. The driver attempted to exit onto 17 Avenue S to avoid the closure, lost control and rolled several times. The vehicle narrowly missed first responders and road crews at the scene who were responding to the earlier collision. Two passengers were ejected.

Two passengers, a 14-year-old girl and a 19-year-old woman, were transported to hospital with serious, life-altering injuries. A third passenger, a 23-year-old man, was also transported to hospital with serious injuries.

The driver, a 21-year-old man, was taken into custody and transported to hospital with minor injuries.

The two men and the 14-year-old girl have since been released from hospital. The 19-year-old woman remains in hospital in serious but stable condition.

Speed and alcohol are believed to be factors in the collision.

After speaking with witnesses, investigators believe several vehicles may have been racing before the collision. Police are asking anyone with dashcam footage from northbound Deerfoot Trail in the moments leading up to the collision to come forward.

The investigation is ongoing and charges are pending.
