An off-duty police officer opened fire inside a Costco Wholesale warehouse store, killing a man who had attacked him and wounding two others, the Corona Police Department said.
Kenneth French, 32, of Riverside allegedly assaulted the Los Angeles Police Department officer Friday night while he was holding his young child, the department said in a statement Saturday. The officer fired his gun, hitting French and two of French's relatives, the department said.
French was killed, the department said. The relatives are in critical conditions at hospitals.
The officer, whose identity is being withheld, was treated and released at a nearby hospital, and the officer's child was not injured, the department said.
The officer was the only person who fired shots in the store, the department said.
The shooting prompted a stampede of frightened shoppers to flee the store east of Los Angeles and seek cover inside.
