The Troubled Journey of Major Hasan

Who Is Nidal Malik Hasan?
The alleged gunman is identified as Major Nidal Malik Hasan, 39, an Army psychiatrist. Beginning the day before the massacre, Hasan allegedly gave away all his possessions, including a desk lamp, air mattress, frozen vegetables and copies of the Koran. He told his imam that he was planning to visit his parents before deploying to Afghanistan. His mother and father, however, had been dead for nearly a decade.
