A gun-wielding mother has been arrested after allegedly firing into a crowd of people outside an apartment complex in a bid to break up a fight - only for the bullet to hit and kill her teenage son. Latoya Tilson, 33, took out a .25-caliber handgun and fired several times into the feuding crowd in College Park, Georgia, on Saturday night after she was hit in the face by someone, police said. But while one bullet struck a 17-year-old boy in the buttocks, another hit Tilson's 15-year-old son, Pierre, in the head. Pierre had apparently been trying to protect his  sister, 13, from the other boy. When first responders arrived at the scene, the teenager was lying unconscious on the floor. He was not breathing and a bullet was lodged in his head. His mother had fled the scene, it is alleged. Scroll down for video .

Pierre and his sister reportedly lived with their father, but had been visiting their mother for the Easter weekend.
