Nidal Hasan

Nidal Malik Hasan (born September 8, 1970) is a Palestinian-American former United States Army major, physician and mass murderer convicted of killing thirteen people and injuring more than 30 others in the Fort Hood mass shooting on November 5, 2009. Hasan, an Army Medical Corps psychiatrist, admitted to the shootings at his court-martial in August 2013.

During the six years Hasan was a medical intern and resident at the Walter Reed Army Medical Center, concerns were raised about his job performance and behavior, specifically comments described by colleagues as "anti-American". Hasan was described as socially isolated, stressed by his work with soldiers and upset about their accounts of warfare. Two days before the shooting, less than a month before he was due to deploy to Afghanistan, Hasan gave away many of his belongings to a neighbor.

Prior to the shooting, an investigation conducted by the Federal Bureau of Investigation (FBI) concluded Hasan's email correspondence with the late Imam Anwar al-Awlaki were related to his authorized professional research and he was not a threat. The FBI, Department of Defense (DoD) and United States Senate all conducted investigations after the shootings. The Senate released a report describing the shooting as "the worst terrorist attack on U.S. soil since September 11, 2001".

Controversially, the Army decided not to charge Hasan with terrorism. A jury panel of thirteen officers convicted him of thirteen counts of premeditated murder, 32 counts of attempted premeditated murder and unanimously recommended he be dismissed from the service and sentenced to death. Hasan is incarcerated at the United States Disciplinary Barracks at Fort Leavenworth, Kansas, awaiting execution.
