A couple dozen people showed up at a Tucson Safeway to lay out flowers and light candles to mark one year since a gunman shot Rep. Gabrielle Giffords and killed six people.

Churches and homes throughout the southern Arizona city will ring bells at 10:11 a.m. MST Sunday, the exact time the gunman shot Giffords and methodically moved down a line of people waiting to talk to her during a congressional meet-and-greet on Jan. 8, 2011.

Six people were killed, including a 9-year-old girl born on Sept. 11, 2001, and a federal judge. Thirteen others were shot, including Giffords.

Giffords visited the Safeway on Saturday with her husband.
