An Arizona sheriff's official says surveillance video shows 22-year-old Jared Loughner shooting a congresswoman in the face.
Pima County Sheriff's Chief Rick Kastigar says Loughner then fires indiscriminately at a group of people sitting in chairs. He then shoots Ron Barber, and U.S. District Judge John Roll gets on top of Barber in an apparent effort to shield him.
Roll was shot in the back and died from his injuries, along with five others. Barber, an aide to Rep. Gabrielle Giffords, was shot in the leg and in the face and neck area and survived. Giffords is hospitalized.
