The shooter died, from a self inflicted gun shot wound, but not before he had left three others dead and wounded sixteen more.
Wednesday afternoon's shooting was quickly followed by orders for everyone to, "Shelter in place immediately. This is not a test."
People were also warned to stay away from windows, while the base was being searched.
Fort Hood was the scene of a shooting on November 5, 2009, in which thirteen people were killed and twenty-nine wounded.
