But at around 10:12 p.m., sheriff's deputies said one of the children, a 4-year-old girl, died at the hospital.
The suspect, identified as 23-year-old Noe Saucedo of Pittsburg, was arrested and booked on one count of murder and two counts of felony evading, police said. According to Sebastian, the white truck initially looked to be exiting Highway 4 at Somersville Road but shifted back onto the highway. Officials say Saucedo is being held in lieu of a $1, 050,000 bail. He was also hospitalized as a result of the collision.
The investigation into this collision is ongoing. Earlier, the countywide officer-involved protocol was invoked.
The case is being investigated by the sheriff's office, Antioch police, the California Highway Patrol and the Contra Costa County District Attorney's Office.
At about 12:47 this afternoon, the Office of the Sheriff received information of a stolen vehicle in Pittsburg. A deputy spotted the vehicle and followed as it headed eastbound on Highway 4.
As the suspect took the off-ramp to Somersville Road, he allegedly accelerated quickly, prompting the deputy to activate his vehicle's emergency lights, sheriff's officials said. The deputy then turned on his emergency lights and the driver ran the red light at the intersection of Delta Fair Boulevard and struck a gray Ford F-150 that was driving south.
Three people, including two children, were injured in the F-150 and were taken to hospitals, according to the sheriff's office.
The injured woman is the mother of the 2-year-old, however, it was not immediately clear if the woman is also the mother of the decedent.
