Army psychiatrist Hasan expected to enter plea on charges in 2009 deadly Fort Hood shootings

The Army psychiatrist charged in the deadly 2009 Fort Hood shooting rampage will finally enter a plea.

Maj. Nidal Hasan is expected to plead not guilty Tuesday, a week before jury selection begins in his court-martial.

In military cases, a defendant is not asked to enter a plea until right before the trial is to start.

Hasan faces execution or life without parole if convicted of 13 counts of premeditated murder and 32 counts of attempted premeditated murder in the massacre on the Texas Army post.

Under military law, a death penalty case requires a plea of not guilty.

If Hasan tries to plead guilty, the judge will reject it and enter a not guilty plea for him.

Trial testimony starts in August following a month of jury selection.
