SALT LAKE CITY (AP) — Court documents say the father of a 4-year-old boy who fired a gun at police told investigators the child had gotten ahold of the weapon before. Police say the boy stuck the gun out of a car window as police arrested his father, who had brandished his gun at McDonald’s workers over an incorrect order on Monday. An officer spotted the gun and instinctively swiped it away, sending the shot into the side of the building. Both the boy and a 3-year-old sibling were taken into the care of child-welfare workers and will be interviewed as part of the investigation. Jail booking documents say the father acknowledged it was not the first time his son had gotten ahold of his gun.
