In photographs, Jack Teixeira, the 21-year-old air national guardsman who has been identified as the prime suspect in the leak of classified intelligence documents, is slim in his dark blue air force uniform. He is youthful looking, barely older than the teenage friends seen in the online group in which the classified documents were leaked.
On Thursday evening, the FBI arrested Teixeira and were searching his home. Video footage from a local TV station showed him being led away in handcuffs.
