Two people are dead. Police are investigating and it appears the shooting occurred downstairs in an employee-only area at the store.
Customers said the store manager got them out.
"We were walking down and all of a sudden, a manager yelled at us to get out, somebody with a gun and the cops stormed and pointing their guns at us," said a customer.
"We were walking down and we heard people yelling and saw people scattering. And then they said, 'Move. Get out of here,'" said a second customer.
ABC7 remains at the scene and will have more information as it becomes available.
