Advocating on Behalf of the American Military and Defense on the War on Terror

Sen. Kay Bailey Hutchinson, R-Texas, told Fox News that military sources informed her that the gunman was about to be deployed to Iraq.

The shooter was killed and two other suspects, who are also soldiers, have been apprehended, Lt. Gen. Robert W. Cone said.

The general said there were "eyewitness accounts of more than one shooter," and the others were tracked to an adjacent facility.

Cone called the attack "a terrible tragedy, stunning." He said the community was "absolutely devastated."
