A senior U.S. official says the soldier accused in the killings is Army Staff Sgt. Robert Bales.
The official spoke on condition of anonymity because of the sensitivity of the investigation into an incident that has roiled relations with Afghanistan.
Bales, who is 38, is a husband and father of two young children and a veteran who was in the midst of his fourth tour in a war zone. But because of a tightly controlled flow of information, many of the details are incomplete and difficult to verify.
It took a fairly long time — nearly a full week — for his name to surface. Part of this was that the only sources talking, the U.S. military and the suspect’s lawyer, John Henry Browne (who spoke about the case earlier this morning), each had vested interests in keeping his identity hidden.
