One of the people fleeing a mass shooting at a midnight screening of "The Dark Knight Rises" at a Denver-area movie theater says he tried to shut the door on the suspected gunman. Twenty-three-year-old Eric Hunter says he and his friends made their way to an exit door after seeing smoke and hearing shots during the movie. When they opened the door, Hunter says they saw two teenage girls -- one of whom had been shot in the mouth. Hunter says he was about to close the door when he saw the shooter, dressed in a bullet-proof vest and a gas mask, approaching. Hunter says he held the door closed and the gunman banged on it for about 10 seconds Afraid that the shooter would start firing through the door, Hunter says he let it go and managed to get out of the theater.
