Nidal Malik Hasan, a 39-year-old U.S. Army psychiatrist of Palestinian descent, killed 13 and wounded 29 at Fort Hood, located just outside Killeen, Texas, in the deadliest mass shooting at a United States military installation. Hasan was shot and taken into custody by responding officers and is now paralyzed from the waist down. He was eventually convicted on 13 counts of premeditated murder and 32 counts of attempted murder and sentenced to death.
