"I turned around and saw these guys come in with hoods over their faces," recalled Linda Lewis, a grocery store employee who lay down on the floor in fear of impending violence. "I thought we'd be next," she said, after hearing two shots. But what she heard was an armed citizen with a concealed-carry permit coming to the rescue. According to authorities, the suspects, one of them holding a pistol, approached the register and demanded cash. A customer waiting in line nearby pulled out a revolver and shot the armed bandit, causing him and his accomplice to flee in a sedan.
