The 22-year-old loner suspected of attempting to assassinate Congresswoman Gabrielle Giffords had his day in court yesterday.

Jared Loughner, with his head shaved, his hands cuffed and a cut on his right temple, was flanked by his attorney Judy Clarke, famous for defending "Unambomber" Ted Kaczynski.

When the judge asked Loughner if he understood he could face life in prison -- or the death penalty -- for killing federal Judge John Roll and five others, he answered "yes," but otherwise stared vacantly during the hearing. Loughner was ordered held without bail. He 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. He will also face state charges.
