TUCSON, Ariz. (AP) -- U.S. Rep. Gabrielle Giffords has arrived in Tucson, Ariz., to begin commemorating the one-year anniversary of the shooting that killed six people and left her and 12 others wounded.
The Arizona Republic says Giffords' first stop Friday was her congressional office where she participated in an emotional ceremony to honor slain staffer Gabe Zimmerman.
Giffords' staff gathered to dedicate a permanent memorial that will welcome visitors to her office: a life-size photo of Zimmerman and a memorial plaque that rests on a stand below it.
Giffords attended the event along with her husband, Mark Kelly.
She also will appear at a candlelight vigil Sunday to mark the anniversary of the shooting, which occurred during a Jan. 8 meet-and-greet.
Giffords still is recovering after being shot in the head during the rampage.
