NORWALK, Conn. (AP) -- It seemed an unlikely excuse from a man suspected of breaking into cars at an auto yard. But police say it appears a Norwalk man was being truthful when he insisted he was just checking the vehicles to make sure they were locked. Employees at Coating's Auto Body caught 20-year-old Alexander Louis Friday and held him for police. The Hour of Norwalk reports Louis told police he was simply making sure each car was locked and if he found one that wasn't, he would open the door and lock it. Police reviewed security video and found his story seemed to check out. They could find no evidence of him going into any of the cars or stealing anything. Louis isn't off the hook completely. He still faces a trespassing charge.
