John Jay Smith kept muttering to police "they killed my son," but really all that the five young men had done was eat some food in a McDonald's parking lot.It was sometime past 1:30 a.m. Wednesday. The five friends were having a mini tailgate, finishing their burgers and fries while standing outside their two cars in a Saint Augustine, Florida, McDonald's lot, when Smith started eyeing them from his truck, the men would soon tell police.
