Jared Loughner: Arizona Shooting Suspect Due in Court Monday, Could Face Death Penalty

TUCSON, Ariz. (CBS/AP) Jared Loughner, the 22-year-old man described as a social outcast with wild beliefs steeped in mistrust, faces a federal court hearing Monday afternoon on charges he tried to assassinate Rep. Gabrielle Giffords and killed others in the Arizona shooting rampage.

The Tucson hearing will come just an hour after President Obama leads a shocked and saddened nation in a moment of silence for the victims and their families at 1 p.m. MST (11 a.m. EST).

Public defenders are asking that the attorney who defended "Unabomber" Ted Kaczynski defend Loughner.

A federal judge, a congressional aide and a young girl were among the six people killed, while Giffords and 13 others were injured in the bursts of gunfire outside a Tucson supermarket.

Authorities weren't saying late Sunday where Loughner was being held, and officials were working to appoint an attorney for him. Heather Williams, the first assistant federal public defender in Arizona, said they're asking that San Diego attorney Judy Clarke be appointed.

Clarke, a former federal public defender in San Diego and Spokane, Wash., served on teams that defended McVeigh, Kaczynski and Susan Smith, a South Carolina woman who drowned her two sons in 1994.

Loughner is charged with one count of attempted assassination of a member of Congress, two counts of killing an employee of the federal government and two counts of attempting to kill a federal employee. More charges are expected.

Comments from friends and former classmates bolstered by Loughner's own Internet postings have painted a picture of a social outcast with almost indecipherable beliefs steeped in mistrust and paranoia.

The counts involving the murder of federal employees, while on duty, could carry the death penalty.
