The Troubled Journey of Major Hasan

Fort Hood's Fatal Afternoon
At 1:30 p.m. on Nov. 5, 2009, a man in military uniform enters one of the buildings making up the Soldier Readiness Processing Center, where hundreds of soldiers headed for Afghanistan are lined up for medical screening. Shouting "God is great" in Arabic, the man opens fire with what is believed to be an FN Herstal tactical pistol, a weapon popular with SWAT teams. Thirteen people are killed, including a woman who was three months pregnant. Walking between buildings, the assailant runs into civilian police officer Kimberley Munley and shoots her several times. As the gunman reloads, he is shot by her colleague Sergeant Mark Todd, who then cuffs him. The Texas base is in confusion for hours.
