Police have identified the woman who Placerville police killed after she commandeered an ambulance on Sunday morning as Linda Carol Clark, 39, of Folsom. Officers shot Clark to death after she led them on a brief low-speed chase, then rammed patrol cars and aimed the ambulance toward police in the driveway of a Placerville home, Placerville Police Chief George Nielsen said. Clark was a mental patient who was "on hold" at Marshall Hospital in Placerville when she escaped in an ambulance parked outside the emergency room, Nielsen said. The case has sparked a debate about whether officers were justified in fatally shooting the unarmed woman.
