Families sifted through waterlogged debris Sunday and stepped inside empty cabins at Camp Mystic, an all-girls summer camp ripped apart by flash floods that washed homes off their foundations and killed at least 70 people in central Texas. Jim Vertuno with The Associated Press was on the site to show how rescuers are maneuvering through challenging terrain as they continued a desperate search for those who are still missing. How many more remain unaccounted for across the Texas Hill Country and beyond remains unclear as authorities haven't given an estimate even though it has been three days since the storm began pounding the state. In Kerr County, home to Camp Mystic and other youth camps, searchers have found 16 bodies since Saturday afternoon. Families were allowed to look around the camp beginning Sunday morning.
