On January 8, 2011, U.S. Representative Gabby Giffords and 18 others were shot during a constituent meeting held in a supermarket parking lot in Casas Adobes, Arizona, in the Tucson metropolitan area. Six people were killed, including federal District Court Chief Judge John Roll; Gabe Zimmerman, one of Giffords's staffers; and a 9-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 to be Giffords, a Democrat representing Arizona's 8th congressional district. She was shot through the head at point-blank range, and her medical condition was initially described as "critical".

Gabrielle Dee Giffords is an American retired politician and gun control activist. She served as a member of the United States House of Representatives representing Arizona's 8th congressional district from January 2007 until January 2012, when she resigned because of a severe brain injury suffered during an assassination attempt. A member of the Democratic Party, she was the third woman in Arizona's history to be elected to the U.S. Congress.
