The California Highway Patrol is investigating a crash Tuesday night on southbound Interstate Highway 680 in unincorporated Alameda County that killed a 39-year-old San Ramon woman.
According to the CHP, Kerri Dir was speeding south on the highway, south of state Highway 84, when the crash happened at about 6 p.m. Her Chrysler veered off the roadway and into a large tree.
Cal-Fire and the Fremont Fire Department assisted in extracting Dir from her damaged car. She was airlifted to Eden Medical Center in Castro Valley, where she died at about 7:40 p.m.
CHP Officer John Bautista said the cause of the crash is under investigation, but that drugs and alcohol have been ruled out as possible factors.
Bautista said there is no relation between the crash and the BB gun shootings that have occurred on I-680 in the Fremont area within the past month.
