Two killed in weekend Calgary road crashes

Calgary police are investigating two fatal collisions that marred the weekend on city streets. The first incident occurred Saturday afternoon on Centre Street North, where a cyclist was killed and a pedestrian sustained minor injuries. Investigators believe the driver of a northbound SUV may have suffered a medical event, causing the vehicle to mount the curb, strike the cyclist, and then collide with other vehicles and a bus stop sign.

The cyclist, a man in his 60s, was pronounced dead at the scene. The driver of the SUV was taken to hospital in critical condition, while the pedestrian's injuries were not life-threatening. Police have found no evidence of alcohol, drugs, or speed being factors in this collision.

A second fatal crash happened early Sunday morning in the West Springs area. A motorcyclist, a man in his 20s, died when his vehicle left the roadway and struck a residence. Authorities are investigating the exact circumstances of this collision, as there were no witnesses.
