It appears that Major Hassan was the only shooter. So far 13 are dead and about 31 have been wounded. Since most handguns don't shoot that many bullets without reloading, it seems logical that he may have had enough time between shots to stop and reload? No one rushed him. Apparently he opened a door to a room containing over 100 people, knelt near the threshold, and fired with a gun in each hand. Someone reported that he was a bit disheveled and that he shouted the standard Muslim "God is good. God is great" as he randomly shot 44 innocent people. Question: Terrorist or just crazy?
