Search efforts continue for a fourth day as a girls' summer camp confirms 27 children and staff are among the dead.

Identification is pending for 22 adults and 10 children. The area hardest hit by the floods was Kerr County, where the Guadalupe River was rapidly overwhelmed by heavy rain on July 4. The river rose to more than 20 feet in a matter of hours at several locations as it rushed downstream toward Kerrville,

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.
