FORT BRAGG, N.C. — A soldier was acquitted of murder Thursday in the 2005 bombing deaths of two superiors in Iraq, triggering loud outbursts and gasps from the slain officers’ families.

A military jury found National Guard Staff Sgt. Alberto Martinez not guilty of two counts of premeditated murder in the deaths of Capt. Phillip Esposito and 1st Lt. Louis Allen. Both officers were killed when an anti-personnel mine detonated in a window of their room at a U.S. military base in Iraq in June 2005.
