He was flown Friday from Kuwait to the military prison at Ft. Leavenworth in Kansas as prosecutors prepared to bring the first formal charges against him.

U.S. military officials said the staff sergeant’s pre-trial confinement at Leavenworth doesn’t necessarily preclude later putting him on trial in Afghanistan.

“No decisions have been made. We’re not there in the process,” said Pentagon spokesman Capt. John Kirby.

Military investigators have said they believe that the man had been drinking alcohol on the night of the rampage.

A lawyer who said he was representing the staff sergeant disputed reports that alcohol, stress or domestic issues caused the man to snap.
