Maj. Nidal Malik Hasan was a soldier who didn't want to go to war, a man of God who defended murder and a doctor who shot up the soldiers he was supposed to heal.
As he lay mute in a hospital bed Thursday night, investigators were scrambling to figure out what prompted his rampage.
Hasan had been a psychiatrist treating wounded soldiers at Walter Reed Army Medical Center in Washington until bad reviews got him transferred to Fort Hood, Tex., in July.
