Jared Lee Loughner's mug shot has just been released by authorities.
Loughner, the alleged shooter of Rep. Gabrielle Giffords and others, shows off an eerie grin and hint of a black eye in the photo. He was quickly identified as a suspect Saturday, taken into custody and has since been charged.
Loughner has been called a "fringe character" and his YouTube and MySpace presence has been closely examined. His behavior at a community college prior to the shooting has sparked questions about whether colleges should be providing more resources for mental health.
