Fort Hood On Nov. 5, 2009, former U.S. Army psychiatrist Nidal Malik Hasan shot and killed 13 people and injured more than 30 others at Fort Hood, Texas. In August, a jury sentenced Hasan to death by lethal injection for his actions, which the Defense Department has classified as “workplace violence.” Hasan is on military death row in Fort Leavenworth, Kan., but experts say it could be more than a decade before he is executed, due to the appeals process.
