Jared Loughner, seen in a police mug shot, is accused in a shooting massacre in Tucson, Ariz. shooting on Jan. 8, 2011.

The suspect in the Tucson, Ariz. shooting rampage pleaded not guilty to dozens of new federal charges accusing him of killing six people and injuring 13 others.

Jared Loughner entered the plea Wednesday to charges that included trying to assassinate U.S. Rep. Gabrielle Giffords, attempting to kill two of her aides and murdering federal judge John Roll and Giffords staffer Gabe Zimmerman.

Loughner is also charged with killing four other people who were not federal employees, causing injury and death to participants at a federally provided activity and using a gun in a crime of violence.

He also will likely face state charges stemming from the Jan. 8 attack at a Giffords event outside a Tucson grocery store.
