Father of Colorado theater shooting victim finds strength in officer who held dying daughter

Two and a half years after a gunman opened fire on a crowded Colorado movie theater, victims and survivors are trying to rebuild their lives. Some have formed bonds with each other, and others have turned to counseling or faith.

The father of the youngest victim, 6-year-old Veronica Moser-Sullivan, says a source of strength is the police officer who carried his daughter out of the theater in his arms.

Ian Sullivan, who wasn't in the theater during the July 2012 attack, says he is troubled that he was unable to protect his daughter. But he says he takes some comfort knowing that the officer is also a father and can understand his pain.

He says text messages and birthday cards from the officer help him realize he is not alone.
