The court martial of Pfc. Carl T. Stovall III resumed Thursday. The 28-year-old is charged with murder for the March 2009 killing of Hungarian laborer Tibor Bogdan, who was digging a hole when shot.
On Wednesday, Army psychiatrist Col. David M. Benedek testified that Stovall suffered from a severe mental disorder that made him unable to understand his actions.
The Killeen Daily Herald reports that Benedek told the court Stovall had secretly believed he was promoted to an Air Force lieutenant colonel before the shooting.
Stovall is a Georgia native who was on his third deployment in the Middle East.
