MAGNA — One person was killed at three others injured in two separate crashes within an hour of each other in Salt Lake County Wednesday night.

About 8:20 p.m., Maria Corona, 60, of Magna, was killed when the car she was in ran a red light at the intersection of 3100 South and 7200 West and collided with another vehicle.

The driver of the vehicle, a 38-year-old woman, was treated for injuries at a hospital and later released, said Unified Police Lt. Justin Hoyal. A 6-year-old boy in the back seat suffered minor injuries.

The 16-year-old driver of the other vehicle was not hurt.

About 40 minutes after that accident, a 54-year-old woman was taken to the hospital after her car collided with a truck at the intersection of 2700 West and 12600 South just after 9 a.m. Hoyal said the truck attempted to make a left turn directly in the path of the oncoming smaller vehicle.

Initially, the 54-year-old driver was thought to be in extremely critical condition, he said. But she was later upgraded to nonlife-threatening condition at the hospital.

The 37-year-old female driver of the truck was not injured.
