A wrecked motorcycle and an SUV were under inspection by the CHP Monday as part of the investigation into a fatal crash Sunday afternoon on Valley Ford Road.
Rider Michael Kolb, 48, of Novato died at the scene.
He and his wife, Martha Kolb, 51, had been riding on the rural west county road at about 3:20 p.m. when their 2008 Harley and an SUV collided, according to initial CHP reports.
Driver Cynthia Callahan, 77, was pulling onto Valley Ford Road from her driveway, near Carmody Road, when the collision occurred.
Her Nissan Rogue SUV turned left into the path of the motorcycle, said the CHP.
