A car crash killed a 21-year-old Cayucos woman late Friday night. She was driving a 1999 Izusu Amigo traveling eastbound on Picachio Road with a male passenger. She lost control and drove down a steep embankment coming to rest in a creek bed. Firefighters used the Jaws of Life to extricate both from the vehicle. The driver died at the scene. The passenger was taken to a local hospital and treated for minor injuries. The CHP is investigating the cause.
