Officers said the store had the photos for over a year, and the clerk tried to verify they belonged to William Hurley. Hurley then became angry, pulled out a gun, hopped the counter and grabbed the photos. Hurley turned to leave, and the clerk called 911. Hurley then turned and came back, and that's when the clerk pulled out his own gun and started shooting, according to officials.
