Authorities say three boys age 15 and under were killed when they fled police in a car at speeds up to 90 mph and then crashed into a house.
California Highway Patrol officials say an officer pulled the car over for running a red light Wednesday evening in Fontana. But the driver sped off.
They say the driver lost control after a brief chase, crashing through a cinderblock wall and into a house.
Authorities say the boys were ages 15, 11 and 9. The teen driver and middle boy were ejected and died at the scene. The youngest boy, who was in the back wearing seat belt, died at a hospital.
The relationships of the boys and what they were doing with the car were not disclosed. No one in the house was injured.
