NTSB investigating crash in Alabama that killed 9 children and 1 adult

Investigators with the National Transportation Safety Board are trying to determine the cause of a deadly 17-vehicle pileup that shut down an Alabama highway. The fiery crash killed 10 people. Nine of them were children.

Eight of the children killed were traveling together in a van after a week-long vacation in Gulf Shores. Some of the kids lived at the Tallapoosa County Girls Ranch — a youth home for neglected or abused children. Their ages ranged from three to 17. "It's a tragedy for Alabama and it's a national tragedy when you lose this many children," said Michael Smith, CEO of the Alabama Sheriffs Youth Ranches.
