Article Photos: Preliminary hearing in Afghan massacre case ends 19/19

  FILE - In this Aug. 23, 2011 file photo, Defense Video & Imagery Distribution System photo, Staff Sgt. Robert Bales, 1st platoon sergeant, Blackhorse Company, 2nd Battalion, 3rd Infantry Regiment, 3rd Stryker Brigade Combat Team, 2nd Infantry Division participates in an exercise at the National Training Center at Fort Irwin, Calif. As Army officials weigh whether a case against a staff sergeant accused of killing 16 Afghan villagers in a pre-dawn rampage will proceed to a court-martial, Robert Bales’ defense team says the government’s case is incomplete. And outside experts say a key issue going forward will be to determine whether Bales, who served tours of duty in Iraq and Afghanistan, suffered from post-traumatic stress disorder. "There are a number of questions that have not been answered so far in this investigation," defense attorney Emma Scanlan told the investigating officer overseeing the preliminary hearing during closing arguments Tuesday, Nov. 13, 2012.
