At approximately 3:56 p.m. on July 18, Huberty drove his black Mercury Marquis sedan into the parking lot of the McDonald's restaurant on San Ysidro Boulevard. In his possession were a 9mm Browning HP semi-automatic pistol, a 9mm Uzi carbine, a Winchester 1200 12 gauge pump-action shotgun, and a cloth bag filled with hundreds of rounds of ammunition for each weapon.[1] A total of 50 customers were present inside the restaurant.[12]
