Jared Lee Loughner, the man accused of going on a shooting spree in Arizona on January 8, pleaded 'not guilty' in court on Monday to murder and the attempted assassination of Rep. Gabrielle Giffords. "Dressed in an orange prison jumpsuit and wearing wire-rimmed glasses, the shaved hair on his head starting to grow back, Loughner said nothing as the plea of not guilty was entered on his behalf," reports confirm. He is due back in court on March 9. [Gawker]
