The Redwood-City office of the California Highway Patrol is looking for witnesses to a crash on Highway 92 in Foster City that killed three people, including a 12-year-old, and left one in critical condition.
The CHP says the 1999 Honda was carrying five people when it struck a guardrail west of Foster City Boulevard on an eastbound off-ramp around 9:45 p.m. Sunday. It flipped over, hit a utility pole and came to rest on its roof.
The 12-year-old, his 16-year-old brother and the 21-year-old driver were killed. Their names have not been released.
The 18-year-old brother of the 12- and 16-year-olds, who was sitting in the back, was in critical condition at Stanford Medical Center. Another 18-year-old, who was sitting in the front, suffered minor injuries.
The cause of the crash is under investigation, and the CHP is looking for help from any possible witnesses. Officers said they don't know if drugs or alcohol were a factor in this collision.
If there are any witnesses to this collision, please contact Officer Graham at (650) 369-626.
