Smallest Victim Has Big Impact

The death of the smallest victim in this weekend's violent rampage is having a big impact on Tucson's children. Christina Taylor Green was a 9-year-old, recently elected to the student council. She became the focal point of President Obama's speech Thursday. Her death is being marked by teddy bears and hand-written notes, as parents try to explain to children why someone would kill Christina for no reason. "You were always a sister to me...and always will be," her best friend Serenity wrote in a card. "People at this point in time are still very numb," said one professional who works with local children.
