IRWINDALE, Calif. (AP) -- Authorities say a man who shot four people and killed two at a Southern California utility office before turning the gun on himself was a 48-year-old man from Riverside County.
Los Angeles County coroner's Lt. Larry Dietz identified the shooter Saturday as Andre Turner of Norco.
Dietz says the two other men killed were 56-year-old Henry Serrano of Walnut and 53-year-old Robert Lindsay of Chino.
The Sheriff's Department says a man and a woman whose names have not been released are in critical condition at a hospital.
Police say Turner went on a shooting rampage Friday through a Southern California Edison office in Irwindale, a small industrial city east of Los Angeles.
Authorities have released no information on a possible motive, and a phone number listed in his name rang unanswered.
