California Highway Patrol are still investigating a crash involving a Marin County sheriff’s deputy and a Moraga woman, whose 2007 Honda Civic swerved into oncoming traffic near the San Geronimo Valley Golf Course Sunday just after 4 p.m. Alcohol does not appear to have been a factor in the crash, and both parties survived with minor injuries. The patrol car driven by Sheriff’s Deputy Michael Dawson, 40, of San Rafael, was pushed off the road and into a drainage ditch just east of Nicasio Valley Road, where it struck a tree – trapping Mr. Dawson in the vehicle. Marin County Fire Department personnel removed the top of the patrol car to free Dawson, who suffered cuts to his left arm and a possible loss of consciousness. The Honda, driven by 62-year-old Christine Walwyn, continued across the westbound lane and came to a stop on the north shoulder. Both parties were treated at Marin General Hospital, and Ms. Walwyn may have broken her ankle, deputies said. Mr. Dawson is expected to return to work in a few days.
