From The New York Daily News:
Scott Smith, of North Ridgeville, had a beige satchel that raised suspicion when he entered the theater. After Smith took a seat, an off-duty Westlake police officer who was providing security to the movie theater asked to search the bag.
The officer found a loaded 9mm Glock handgun, multiple loaded magazines and three knives inside, Westlake Police Lt. Ray Arcuri said. An additional knife was found underneath his clothes.
