When authorities arrived on the scene, they found four victims, one of them being fatally shot, and another one, an off-duty police officer. The off-duty police officer discharged his gun at some point, said LAPD Officer Greg Kraft.

Others who were just simply shopping when the shooting occurred say they tried to leave the store but the emergency doors would not open leaving many bystanders with injuries.

Witnesses said a man with a Mohawk haircut was arguing with a woman with a child inside the store when the shots were fired.

“It’s not very fun when you’re scared and you’re running for your life and you’re trying to open a door that says ’emergency’ and they don’t open,” shopper Rachel Flores told the local news. “Everybody was freaking out. People were falling over each other… Everybody’s running around.”
