CNN reported: "Christina's family, friends, classmates, and hundreds of mourners filed in to the St. Elizabeth Ann Seton Catholic Church in Tucson for a funeral service Thursday afternoon, all of them passing under a giant American flag that was recovered in the aftermath of the terror attacks in New York on September 11, 2001 -- the day Christina was born."

Green and 49 other babies born on 9/11 were featured in the book "Faces of Hope." Sales of the book have reportedly increased this week.

According to Reuters, Green was the granddaughter of former pro baseball manager Dallas Green. She loved gymnastics, dance, swimming and had hoped to be the first female major-league baseball player. Green was also elected to her elementary school's city council.

The Washington Post reported: "Christina's is the first in a series of funerals for the slain across Tucson. For the country, the celebration of the youngest victim will likely be the most poignant. President Obama, in his eulogy delivered here Wednesday night, made the third-grader the face of all that America's democracy should be." 

"She showed an appreciation for life uncommon for a girl her age," President Barack Obama said. "I want to live up to her expectations, I want our democracy to be as good as Christina imagined it, I want America to be as good as Christina imagined it."

Five others were killed during the shooting, while more than a dozen others were wounded, including Congresswoman Gabrielle Giffords.

Jared Lee Loughner, a 22-year-old college dropout, has been charged in the shootings.
