California Highway Patrol investigators are looking into the cause of a fatal accident on northbound I-680 at the Monument Blvd. offramp early Saturday.
Officers were advised of a hit-and-run accident on the freeway at 4:40 a.m. south of Monument Boulevard. While investigating, officers found the body of a 20-year-old Antioch man in the fast lane of the freeway, apparently after he was struck by three cars – the first of which left the scene, according to the CHP.
Investigators believe the unidentified man was standing in the northbound lanes when a white sedan hit him and continued on its way. After the initial collision the man was struck by an Audi SUV driven by an Oakley man and then a Toyota Corolla driven by a 22-year-old woman from Concord.
The drivers of the Audi and the Toyota stopped at the scene and provided statements to officers. The first car to hit the pedestrian was described as possibly being a white Acura Integra.
The pedestrian was pronounced dead at the scene. Subsequent investigation determined that the dead man may have been left on the freeway by friends, who drove off without him.
Alcohol or drugs do not appear to have played a part in the incident. Anyone seeing the hit-and-run or events leading up to it is asked to contact Officer Mitchell at 925.646.4980.
This was the second fatality on Highway 680 this morning. Another person died in a rollover crash in Pleasanton near Stoneridge Drive earlier in the morning.
