WASHINGTON (AP) A law enforcement official says a shooting suspect at a U.S. military base in Texas has been identified as Army Maj. Malik Nadal Hasan.

The official said Hasan, believed to be in his late 30s, was killed after opening fire at Fort Hood. The official spoke on condition of anonymity because he was not authorized to discuss the case publicly.

The official says investigators are trying to determine if Hasan was his birth name, or if he changed his name and converted to the Islamic faith at some point in his life.
