For the first time since she was shot there a year ago, Rep. Gabrielle Giffords (D-Ariz.) on Saturday returned to site of the Tucson, Ariz., mass shooting where six people died and another 13 were wounded.

"Gabby just visited the Safeway for the 1st time since 1/8/11. It's been a tough year, but we're lucky to have so many people standing w/us," her husband, astronaut Mark Kelly, posted on Twitter on Saturday afternoon.

Giffords arrived back in Tucson on Friday two days before a ceremony to mark the one-year anniversary of the shooting, in which a gunman opened fire at a public meeting she was holding with constituents outside the Safeway on Jan. 8, 2011.

Six people were killed and thirteen people, including Giffords, were wounded.

On Friday, Giffords dedicated a permanent memorial in her Tucson office to her former staff member Gabe Zimmerman, who died in the shooting.

The Congresswoman is also expected to attend a candlelight vigil to be held at the University of Arizona at 6:30pm local time Sunday.
