Gabrielle Giffords (D-AZ) sits with her mother Gloria Giffords (R) the day after the launch of NASA space shuttle Endeavour and the day before she had her cranioplasty surgery, outside TIRR Memorial Hermann Hospital May 17, 2011 in Houston, Texas.
The Los Angeles City Hall bell was scheduled to be rung at 9:11 a.m. Sunday as part of a nationwide commemoration of the first anniversary of the shooting in Tucson, Ariz. that killed six people and left 13 wounded, including Rep. Gabrielle Giffords, D-Ariz.
Tucson Mayor Jonathan Rothschild sent a letter Tuesday to Mayor Antonio Villaraigosa, in his role as president of the U.S. Conference of Mayors, asking mayors to ring bells in their cities at 10:11 a.m. Mountain Standard Time Sunday, the time the shooting took place, to honor its victims and survivors.
Villaraigosa asked Councilman Tom LaBonge to ring the City Hall bell. Villaraigosa is in San Francisco for the inauguration of Mayor Edwin Lee for a full, four-year term.
Giffords and other survivors of the deadly shooting rampage are gathering in Tucson to reflect and remember.
On Jan. 8, 2011, deranged gunman Jared Lee Loughner shot Giffords in the head and mowed down a line of people waiting to talk to her outside a grocery store.
Six people were killed, including a 9-year-old girl born on 9/11 and a federal judge. Thirteen others were shot, including the congresswoman.
Giffords, who has undergone a year of grueling therapy, plans to appear at an evening candlelight vigil. An interfaith service is also planned.
Loughner has pleaded not guilty to 49 charges in the shooting. He is being forcibly medicated in prison in a bid to make him mentally fit for trial.
