A 23-year-old driver died when she collided with two other vehicles Friday night in Antioch, according to police.
Around 9:30 p.m., the woman was driving a pickup truck, traveling west on Lone Tree Way, near the entrance to Slatten Ranch Shopping Center at 5749 Lone Tree Way, police said.
She failed to stop at a red light at Slatten Ranch Road, however, and struck a vehicle that was making a left turn into the shopping center.
The two vehicles then collided with a third vehicle that was turning right from the shopping center, attempting to head west on Lone Tree Way, according to police.
The collision caused the pickup truck to roll several times. The driver, who was the only passenger in the truck and was not wearing a seatbelt, was ejected from the truck. She was pronounced dead at the scene, police said.
The occupants in the two other involved vehicles suffered injuries that were not considered life-threatening, police said.
Investigators suspect that speed and alcohol may have contributed to the collision. The identity of the victim has not been released and police are continuing to investigate the incident.
