CORONA (CBSLA) — Corona police on Saturday said the shooting inside a Costco Friday evening involved an off-duty LAPD officer who was, in fact, the shooter.

The officer got into some kind of altercation with a man (described as having a Mohawk-style haircut) and felt threatened, authorities said.

According to the Corona Police Department, officers were sent to the scene at 7:46 p.m. after receiving calls of an active shooter inside and arrived at the scene in just under a minute.

Officers reported finding one dead and three wounded. The injured were transported to the hospital.

As of Friday evening, police have not released the names of the dead and wounded.

On Saturday, Corona police identified the dead man as 32-year-old Kenneth French of Riverside.

Authorities said the unidentified officer was shopping with his family when French (whom the officer did not know) assaulted the officer while the officer was holding his young child. They went on to say that two of French’s family members were also injured and are in critical condition.

The off-duty officer was transported to a local hospital where he was treated and released. His child was not injured.

Witnesses at the scene told reporter Nicole Comstock they heard an argument before hearing seven or eight shots.

About an hour after the shooting, Corona police said there was no “apparent threat”.
