Edison shooting: Workers wounded by gunman in critical condition

Two Southern California Edison employees wounded Friday in the deadly workplace shooting in Irwindale remain hospitalized in critical condition, a Los Angeles County sheriff's spokeswoman said.

The two, identified only as a man and a woman, were injured when a fellow employee opened fire about 1:30 p.m. in the first-floor offices of an Edison information technology facility.

The shooter killed two other workers before taking his own life, authorities said.

Sheriff's homicide detectives recovered a semiautomatic handgun at the scene. Earlier, the weapon had been described as a rifle.

Francisco said it appeared that all the victims worked with the shooter. He apparently had been at work since the morning, she said.

"We don't know if he left and came back," she said. "The witnesses are being interviewed now."

The names of the victims and the gunman have not been released.
