Christina-Taylor Green, the 9-year-old girl killed in Saturday's shootings in Tucson, donated her organs.

She was one of six people killed in the shooting that targeted U.S. Rep. Gabrielle Giffords outside a Safeway store northwest of Tucson. Giffords remains in critical condition.

More than 1,700 people packed St. Elizabeth Ann Seton Catholic Church, tucked into the foothills of the Santa Catalina Mountains, for Christina-Taylor's funeral Thursday afternoon. The congregation included Mark Kelly, the husband of Giffords; senators John McCain and Jon Kyl, and baseball greats like Ryne Sandberg and Pat Gillick. Her father, John, is a scout for the Los Angeles Dodgers.

The Most Rev. Gerald Kicanas, Bishop of Tucson told the crowd that Christina-Taylor's organs were donated.

And a friend helping the Green family said they received a call yesterday from the organ donation network, telling them that Christina-Taylor's donation had already saved the life of a child on the East Coast.

The little girl loved ballet, gymnastics and baseball, the only girl on her team.

Christina-Taylor was born on Sept. 11, 2001, and liked to think of herself as something good that came into the world that awful day.

Mourners entered her funeral beneath a billowing tribute: the National 9/11 flag, a 45-pound patchwork of tattered fabric rescued from the collapse of the Twin Towers. The 20-by-30-foot banner soared over the sidewalk between the outstretched ladders of two fire engines, and was hand-carried by a New York firefighter to Tucson to honor Christina-Taylor and her ideals.
