U.S. Rep. Gabrielle Giffords is attending a candlelight vigil in Tucson to honor the six people killed one year ago in a deadly supermarket shooting.
A crowd of about 1,000 people cheered as she emerged from backstage and walked up stairs onto the stage.
The remembrance at the University of Arizona capped off a day of events, including a church service that drew hundreds in the afternoon and a citywide bell-ringing at 10:11 a.m., the exact time a gunman started shooting at a Safeway political event.
An orchestra played Sunday evening as more than a thousand people gathered on a cold, palm tree-lined lawn for the vigil.
Giffords was shot in the head severely wounded. She has rarely appeared in public. Her husband, former astronaut Mark Kelly, was expected to speak at the Sunday evening event.
