On January 8, 2011, U.S. Representative Gabrielle Giffords and eighteen others were shot during a constituent meeting held in a supermarket parking lot in Casas Adobes, Arizona, in the Tucson metropolitan area. Six people died, including federal District Court Chief Judge John Roll; Gabe Zimmerman, one of Rep. Giffords' staffers; and a nine-year-old girl, Christina-Taylor Green. Giffords was holding the meeting, called "Congress on Your Corner" in the parking lot of a Safeway store when Jared Lee Loughner drew a pistol and shot her in the head before proceeding to fire on other people. One additional person was injured in the immediate aftermath of the shooting. News reports identified the target of the attack as Giffords, a Democrat representing Arizona's 8th congressional district was shot through the head at point-blank range.
