That’s when someone in the car allegedly shot at the officers, and they fired back.
“I heard a gunshot. I think one or two shots. When I came outside, I heard cars spinning up the block,” said witness Patrick Simpson.
Simpson owns a nearby restaurant and said people ran for cover inside.
“They look frightened. They were saying, ‘There’s a shooting outside. There’s a shooting!'” he said.
