KILLEEN, Texas (AP) - Police say a Central Texas teenager has been charged in the fatal shooting of a Fort Hood soldier who was attacked outside a convenience store.

Killeen police on Tuesday arrested 17-year-old Terry Grant Scott of Killeen in connection with the Jan. 2 attack. Police on Wednesday did not immediately provide additional information on Scott's jail status or an attorney.

Fort Hood officials say Spec. Austin James Sampson of Bliss, N.Y., died Friday at a Temple hospital. Police say two men who were with Sampson in an SUV were critically wounded by the gunfire in a convenience store parking lot.

Investigators have not announced a possible motive for the shootings.

Sampson had been assigned to Fort Hood's Headquarters Troop, 3rd Squadron, 3rd Cavalry Regiment, since February 2010.
