Jared Lee Loughner, the man accused of shooting former Rep. Gabby Giffords and 18 others in Tuscon, Ariz., in 2011, may plead guilty this week. He may enter his plea on Tuesday during a status hearing, and a federal official told NBCNews.com  that if his plea is accepted, Loughner will be required to serve life in prison. However, if he stands trial, he faces the possibility of the death penalty if convicted.
The federal judge handling the case had scheduled a status hearing in Tucson for this Tuesday to get an update from prison doctors treating Jared Loughner, who's been undergoing mental health treatment in a Bureau of Prisons hospital since shortly after the shooting.
