Boy, 6, dies days after South Carolina school shooting

Jacob Hall had been fighting for his life at a hospital after a bullet struck him in a main artery in his leg, causing him a major brain injury due to a "catastrophic" loss of blood, his doctor said.

After the slaying, the teen — who is not old enough to have a driver's license — drove a pickup truck about 3 miles down a country road, crashed at the school and started firing with a handgun, authorities said.

Dr. Keith Webb called Jacob a "tremendous fighter" but said he "unable to overcome the catastrophic blood loss and resulting cardiopulmonary arrest caused when the bullet hit his femoral artery."
