(CNN) - Jared Lee Loughner is expected to plead guilty Tuesday to the shooting that killed six people and wounded Congresswoman Gabrielle Giffords last year in Tucson, Arizona. That plea could happen if a judge finds Loughner competent to stand trial. Loughner had earlier pleaded not guilty to murder and attempted murder charges.
But a court order released today suggests Loughner's attorneys plan to change that plea at a hearing scheduled for tomorrow.
Giffords was one of 13 people wounded in the shooting. She has since retired from Congress.
