FORT HOOD, Texas — A witness to the 2009 Fort Hood shootings says she had to quickly decide who she could save, so she used a black marker to write a "D" on the foreheads of the victims she couldn't.
Sgt. 1st Class Maria Guerra recalled those moments while testifying Thursday at the trial of Maj. Nidal Hasan. He's accused of killing 13 people and wounding 32 others that day at the Texas military base.
Hasan is acting as his own attorney. He raised a rare objection when Guerras said she heard the gunman silence a woman who was yelling, "My baby!" Hasan asked the judge to remind Guerra she was under oath.
Guerra said she didn't want to change her testimony.
Hasan challenged no other witnesses and said little during the trial.
