OAKLAND -- A woman died in the early morning hours of New Year's Day after a car she was riding in rolled over and crashed on Interstate 580 -- a crash the driver told authorities was caused by an unidentified second vehicle.
Around 2:36 a.m., CHP officers and Oakland police responded to westbound I-580 just west of Park Boulevard for reports of a solo vehicle crash.
When officers arrived, they found a woman trapped in the front passenger's seat of a Ford Expedition resting on its roof on the Park Boulevard on-ramp. The driver was able to get out of the car and did not suffer any injuries.
Fire crews and paramedics attempted to get the woman out of the car and perform CPR, but she was declared dead at the scene a short time later. Authorities have not yet released the woman's identity
The driver told investigators that a sedan struck his car and caused the crash. However, according to the CHP, the driver was unable to give a description of the car or a license plate number.
Witnesses told officers they did not see any other cars in the area, and officers weren't able to determine whether another vehicle was involved.
No arrests have been made.
The CHP is asking for the public's help to try and determine if anyone may have seen the Ford Expedition before the collision and if they could prove or refute the driver's claim that there was a second car.
An investigation into the crash is ongoing. Anyone with information can call the CHP Oakland Area Office at 510-450-3821, or the CHP's nonemergency public access number at 1-800-TELL-CHP.
