Meagan Kathleen Campbell, 33, faces felony charges after a motorcyclist suffered critical injuries and five occupants of a Saturn sedan suffered injuries, ranging in seriousness from moderate to life-threatening, said CHP Officer Brandon Correia.
The first accident was reported at 5:12 p.m., when the white Subaru driven by Campbell struck a Harley-Davidson motorcycle on eastbound Highway 4 just east of the County Highway J4 (Byron Highway) intersection, Correia said.
Campbell allegedly drove away from that accident, headed east on Highway 4, where, about 500 feet from the first accident scene, the white Subaru ran head-on into a westbound Saturn sedan carrying five people. All occupants of the Saturn were injured - three with critical injuries and two with moderate injuries. They and the motorcyclist were all taken, in ambulances or by helicopter, to area hospitals --- two each to John Muir Medical Center in Walnut Creek, Eden Medical Center in Castro Valley and Sutter Delta Medical Center in Antioch.
Campbell suffered minor injuries, Correia said.
Highway 4 was closed in both directions for about 90 minutes after the accidents, and reopened about 6:45 p.m.
