Later that day, an undercover investigator assigned to watch the McDonald house noticed that the garage had been damaged and saw Andre McDonald backing out of the driveway. The investigator followed him to a nearby gun shop where additional investigators, who were called to the scene, observed Andre McDonald purchasing a 9mm handgun and ammunition.
