John Roll

As the frenzied attack continued, Loughner turned his gun on the then district director, Ron Barber.

Another attendee, Judge John Roll, leapt in between the two in a moment of sheer bravery.

Uh, John Roll pushed him on the table, jumped on top of him, and took a fatal, fatal wound in the back.

I walked out and the first body that I came to was Judge John Roll.

I couldn't tell where he was shot, and I kept asking, there were s- a few people crawling around, "Where is he shot? Where is he shot?" I just started doing CPR.

It was futile.

That's B- that's how Bill's made.

Along with the young child, five adults were also victims of the brutal spree.

And there it is, four years into representing Arizona's 8th Congressional District as she was hosting a Meet Your Congresswoman event in a supermarket parking lot in the Tucson area on January 8, 2011, when she and 18 and others were shot by a mass shooter.

Six people were killed, including federal district court chief judge John Roll, Gabe Zimmerman, one of Giffords' staffers, and a nine-year-old girl, Christina Taylor Green.

Giffords was shot, as you just heard, at point-blank range in the head before the shooter opened fire on the others.

It was the beginning of more than a decade of recovery.
