Coroner ID's motorcyclist who died in chain-reaction accident in San Francisco

Motorcyclist killed in DUI chain-reaction crash

Two drivers suspected of driving under the influence were arrested following a fatal motorcycle crash that tied up two freeway ramps and mired traffic in San Francisco for about five hours on Tuesday morning.

SAN FRANCISCO - The San Francisco Medical Examiner on Wednesday identified the motorcyclist who died in a chain-reaction accident on the freeway as Colin Rumbold, 34, of Alameda County.

Rumbold died early Tuesday morning during a string of events that began about 3:30 a.m. on the US 101 to Interstate 80 connector in San Francisco coming off the Bay Bridge.

Rumbold came upon a Nissan sedan that was stopped in that area, blocking a lane of traffic and then lost control, trying to avoid it," CHP Officer Mark Andrews said.

Rumbold fell about 40 feet down to the freeway, and at that time, a Honda sedan was traveling on I-80 westbound to the US-101 southbound connector ramp, the CHP said.

Rumbold fell on top of the Honda.

Just then, the CHP said the driver of a Subaru Forester approached the back of the Honda, slamming into the back of it.

Rumbold was likely hit by more than one car, the CHP said.

The drivers of the Nissan and Subaru were both arrested and booked on suspicion of driving under the influence – a misdemeanor.

The driver of the Honda was not arrested and sustained minor injuries, the CHP said.

Neither driver will be charged with the death of the motorcyclist, the CHP said, as they were not the cause of the crash.

Still, the CHP warned that drinking and driving is illegal and dangerous.

Any witnesses should contact Officer Israel Garcia at the CHP San Francisco Area office at (415) 557-1094.
