Suspect in Tucson shooting rampage enters plea

TUCSON, Ariz. – The suspect in the Tucson, Ariz., shooting rampage has pleaded not guilty to dozens of new federal charges that accuse him of killing six people and wounding 13 others.

Jared Lee 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.

He also is charged with causing the deaths of four others who weren't federal employees, causing injury and death to participants at a federally provided activity and using a gun in a crime of violence.

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