A gunman burst into a Dallas County dollar store in Alabama Thursday and threatened to kill everyone while forcing an employee and customer toward the break room. Witnesses say he was waving his gun around in the air. The customer who was being escorted by the gunman at gunpoint had a concealed firearm and once the employee walked through the door to the break room, the customer quickly turned around and shot the gunman once in the chest. He was pronounced dead at the scene.
Police are investigating, and did not comment on whether the customer had a concealed carry permit.
