Families sifted through waterlogged debris and stepped inside empty cabins at Camp Mystic, an all-girls summer camp ripped apart by flash floods that killed at least 70 people in central Texas.

Although Kerr County was hit hardest by flooding, at least seven others have been confirmed dead in different parts of Texas. About 150 miles east of Camp Mystic, Travis County has confirmed at least four deaths, county spokesperson Hector Nieto told CBS News by phone Saturday night. Travis County includes the Texas capital city of Austin.

Gov. Greg Abbott said there are at least 68 people dead in Kerr County, including 40 adults and 28 kids, after flooding hit central Texas. Ten children from Camp Mystic and one counselor are still unaccounted for.
