PHOENIX -- Phoenix police say a woman died after her vehicle collided with a scooter and two other cars.
Sgt. Trent Crump says the incident occurred in central Phoenix on Saturday around 4:30 p.m. near the intersection of Thomas Road and 16th Street.
According to authorities, the woman's Ford Focus was traveling eastbound on Thomas when it struck the motorized scooter.
Crump says the Ford Focus continued through the intersection, where it hit the other vehicles before stopping.
“We were stopped at the light to turn left and got sideswiped by one of the cars, and she went across and went head-on into another car,” said Robert Fairbanks, who was involved in the accident. “It's not easy when you see somebody slumped over in a car, and they take them off, and you find out that they’re gone. It’s not a good feeling."
Crump says the 77-year-old woman was pronounced dead at a hospital.
Phoenix firefighters say two other people were treated at the scene and released.
Investigators are trying to determine what caused the accident. They say initial evidence shows the woman may have died of natural causes or a medical condition.
