FORT HOOD, Texas — The Army psychiatrist charged in the 2009 Fort Hood shooting rampage will represent himself at his upcoming murder trial, meaning he will question the more than two dozen soldiers he’s accused of wounding, a military judge ruled Monday. Maj. Nidal Hasan’s attorneys will remain on the case but only if he asks for their help, the judge said. Hasan, 42, faces the death penalty or life in prison without parole if convicted of 13 counts of premeditated murder and 32 counts of attempted premeditated murder.
