The concealed carry license holder opened fire on Dec. 30 when two men tried to steal a vehicle from the 4800 block of North Moody Avenue in Jefferson Park, Chicago police said.  The men were trying to steal a vehicle belonging to a 25-year-old woman when a friend of hers, a 26-year-old man with a concealed carry license, saw one of the two men appear to reach into his waistband.
