Ft. Hood suspect remains in coma

WASHINGTON (AP) - Authorities said Fort Hood shooting suspect Nidal Malik Hasan remains in a coma but is expected to live.

A federal law enforcement official said investigators have not been able to talk to Hasan since the deadly rampage that left 13 people dead and injured 30 others at the sprawling Army post in Texas on Thursday.

The initial investigation shows that Hasan allegedly used only one gun during the attack -- a 5.7-caliber semiautomatic pistol.

Army officials said Hasan also was carrying another handgun. But the law enforcement official said there's nothing so far to indicate the second weapon was fired.

The law enforcement official spoke on condition of anonymity because the investigation is ongoing.
