DUBLIN — The driver of a white BMW 2004 linked to a hit-and-run accident Monday evening on northbound Interstate 680 has turned herself in, according to the California Highway Patrol.
Sobhanieh Mostakhdemin, 25, of San Mateo, turned herself in Wednesday afternoon at the CHP's Dublin office and was arrested on suspicion of reckless driving and leaving the scene of an accident that caused injury, CHP Officer Steve Creel said.
Motorcyclist Robert Demartino Jr., of Livermore, was hit Monday on northbound Interstate 680 near Sunol Boulevard in Pleasanton, Creel said.
Witnesses said the driver of a white BMW had been traveling at more than 100 mph, nearly colliding with several vehicles. The driver began closely following a 2005 Chevrolet SUV before a curve in the highway, and Demartino was just ahead on a 2007 Suzuki GSX-R750.
The BMW struck the motorcycle's rear wheel and Demartino was thrown to the pavement, where he hit his head, Creel said. Demartino was taken to Eden Medical Center in Castro Valley, where he is listed in stable condition.
The BMW struck both the SUV and Demartino's motorcycle, but only Demartino was injured, Creel said.
Creel credited two eyewitnesses with getting the BMW driver's license plate number, which he said led officers to Mostakhdemin.
