Christina-Taylor Green, 9, was excited about going to Rep. Gabrielle Giffords' informal town hall event this weekend. She started becoming interested in politics during the last presidential campaign.
"She had all kinds of patriotic little pins and what not and then she was on her way to being very political and very interested in government ...," her mother, Roxanna Green, said.
Christina-Taylor was a straight-A student. The "9/11 baby" sang on the church choir and was best friends with her older brother.
She had just been elected class president at Mesa Verde Elementary School and had planned to start a club at her school to help less fortunate classmates. It was that civic-mindedness that led her to a Safeway supermarket in Tucson Saturday morning.
Christina-Taylor "talked about getting all the parties to come together so we could live in a better country," her mother said Sunday. "She was going to Giffords' event to ask questions about how she could help and to learn more about politics in our country."
Her promise of a bright future in public service was snuffed out when she and five other people were shot and killed by a man who police say went to the venue to kill Giffords, 40. The congresswoman remains in serious condition after being shot in the head. Fourteen other people were wounded.
Among the dead are a federal judge and a Giffords aide. Christina-Taylor was shot once in the chest.
The alleged shooter, 22-year-old Jared Loughner, has been charged with multiple counts of murder and attempted murder.
"It's very ironic, and it says something about society when she comes in to the world on 9/11 and at 9 years old she leaves it this terrible day, but we wouldn't take back any of the nine years we had with her," her father, John Green, said.
Said her mother: "She had a great morning, she got up early ... and was talking about the event, and how excited she was. She was very mature for her age."
Christina-Taylor liked to sing and dance, and loved sports. She was the only girl on her Little League team, which wasn't surprising, considering that baseball is the family business.
Her father works for the Los Angeles Dodgers and her grandfather, Dallas Green, managed the Philadelphia Phillies. He led them to the World Series in 1980.
Christina-Taylor was a tireless debater, and very strong-willed.
"She was tenacious ... We nicknamed her the bobcat," her father said in an interview with "Good Morning America" anchor George Stephanopoulos. "She'd give a little snarl when she didn't like something."
Her parents described their daughter as a selfless girl.
"She was vibrant, she truly just wanted to be helpful in the community and help others and just get involved," her mother said. "She always wanted to get involved."
Indeed, shortly before she was killed, she had cleaned out her room.
"She put all these toys and clothes and shoes in various bags and she couldn't wait to go give them away to someone who was less fortunate ... she was strong, she was brave, she was fearless, but she also had a kind heart and she was sweet," her mother said.
The kind-hearted girl was very close to her 11-year-old brother, Dallas.
Dallas was supposed to have attended the congresswoman's event Saturday, but he had karate practice.
Dallas has Asperger's syndrome, and his sister took care of him in her spare time.
