The nine-year-old girl who was born on Sept. 11, 2001 was carried to her funeral beneath a flag that survived the attack that day on the World Trade Center -- a symbol of both tragedy and resilience, reports CBS News correspondent John Blackstone.

The service for Christina Green was private, but in death she's become a public figure.

"In Christina we see all of our children," said President Barack Obama as he spoke at a memorial service for the Ariz. shooting victims on Jan. 12.

At last night's tribute to the victims in Tucson, the President acknowledged the special impact of Christina's death - and life.

"I want to live up to her expectations," said the President. "I want our democracy to be as good as Christina imagined it."

While Christina has touched the nation, for the hundreds lining the route to her funeral, she is Tucson's child.

"I pray every night that she's in a happy place and that she's with God now," said Isabel Torres, Christina's classmate.

Mourning in Tucson

Hardest hit by the nine-year-old's death are those most like her: the children of Tucson. Classmate Alexis Strauss says Christina's friends have so many questions.

"We were just wondering what the last words to her brother were," said Strauss.

Among the tributes at Christina's school is a note from the Little League team where she was the only girl.

Dave Britton brought six of his seven boys. Isaac was in the third grade with Christina.

"She's in fact the same age as me," said Isaac. "It's just sad."

Along with the sadness there is also a new fear.

"It could have been me or any of my brothers," said one of the boys.

Since the shooting Kelley Fourcier has been holding her 7-year-old twins, Ashley and Brianna, closer than ever.

"It's sad that you just go to a grocery store and your kids could be killed," said Fourcier. "It's horrible."

At Christina Green's funeral we learned of yet another way she touched lives: as an organ donor.
