Christina-Taylor Green, 9-year-old killed in Tucson, remembered, mourned

Christina-Taylor Green, 9-year-old killed in Tucson, remembered, mourned: "Christina-Taylor Green's short life was pinned between two national tragedies: She was born on Sept. 11, 2001, and she died Saturday as a gunman apparently targeting Rep. Gabrielle Giffords (D-Ariz.) shot at least 18 people in Tucson.

Christina-Taylor, a budding elementary school politician, was among those killed. The third-grader had gone to meet Giffords with a neighbor when a gunman, identified by authorities as 22-year-old Jared Lee Loughner, opened fire at a political meet-and-greet outside a grocery store. Christina-Taylor died at University Medical Center."
