TUCSON (KGUN9-TV)- They hug, and pray, and write messages to Christina Taylor Green in colorful chalk on the ground.
Today, she would have turned 12 years old, and as family and friends gather at her memorial park to celebrate, her father remembers the day she came into this world.
"Those terrorist attacks on Christina's birthday," John Green told us, "it was such a tragedy. We were overwhelmed in the hospital, but then, we started thinking, you know, Christina was sort of a glimmer of hope on a terrible day."
And 12 years later, their daughter isn't here.
"It's very challenging," Christina's mother, Roxanna, said. "It's very difficult. It's always a hard day. You know, we miss her so much."
The youngest victim of the January 8th tragedy, Christina was 9 years old when she passed away, but her parents and friends say today is about honoring who Christina was, and the impact she made on our community.
"She was always happy and always had a positive attitude," one of Christina's friends, Jamie, remembers. "If you were upset, she would make you feel better, and she was just always smiling, and a really good friend."
Her favorite colors were pink and purple.
She loved butterflies and balloons, so in honor of her life, the lives of other January 8th victims, and those who died in the September 11th terror attacks, 12 pink and purple balloons float away in the Tucson sky.
