Attorneys for the Army psychiatrist charged in the Fort Hood shooting rampage have urged a commander not to allow death as a punishment in the case.

It's unclear when Fort Hood's commanding general will decide whether Maj. Nidal Hasan is court-martialed and faces the death penalty.

Hasan's lead attorney, John Galligan, says he urged Lt. Gen. Donald Campbell on Thursday not to authorize seeking the death penalty. Galligan says such cases are more costly, time-consuming and restrictive.

Hasan is charged with 13 counts of premeditated murder and 32 counts of attempted premeditated murder in the November 2009 shootings on the Texas Army post.

If Campbell decides that Hasan will be tried without the death penalty being a punishment option to military jurors, a conviction would bring life imprisonment without parole.
