Three killed in office shooting
Three people have been killed and two more injured in a California office complex shooting, police said.
Baldwin Park Police Captain Michael Taylor said the suspected gunman is among the dead.
The people were shot on Friday afternoon at the Southern California Edison office building in Irwindale, near Los Angeles.
One of the dead was discovered inside the building, and another died en route to hospital. Two others have unspecified injuries and their conditions are not known.
The suspected gunman is believed to have shot himself, Mr Taylor said.
Edison International chairman and CEO Ted Craver confirmed that the victims and the suspected gunman were Southern California Edison employees, four full-timers and one contract worker. Mr Craver said "this is one of the most horrible days in our company's history".
One of the shooting victims was a woman and the other four were men. Mr Craver did not specify which were living or dead, and was careful not to provide identifying details for the victims, saying the company is still working to contact next of kin.
There was no immediate word on what prompted the gunfire.
Multiple media reports said at least two victims targeted by the gun-toting employee were believed to be company managers. Police said they could not confirm those reports.
