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 82 people in central Texas. Regan Brown walked through the flood-ravaged remains of his parents’ home in Hunt, Texas, on Sunday. His parents, both in their 80s, escaped the rising waters as flash floods swept through the area. They also rescued their 92-year-old neighbor, who was trapped in her attic. "We’ve been trying to help our neighbors, salvage what we can. Everything’s soaked, five times heavier than normal. It’s a slow process," Brown said. He said that their elderly neighbor told him she had "never seen anything like this." "It’s the highest anyone we know has ever seen the water in this valley," said Brown. Rescuers maneuvering through challenging terrain continued their desperate search for the missing, including 10 girls and a counselor from the camp. For the first time since the storms began pounding the Texas, Gov. Greg Abbott said there were 41 people confirmed to be unaccounted for across the state and more could be missing. In Kerr County, home to Camp Mystic and other youth camps in the Texas Hill Country, searchers have found the bodies of 68 people, including 28 children, Sheriff Larry Leitha said in the afternoon. He pledged to keep searching until “everybody is found” from Friday's flash floods. Ten other deaths were reported in Travis, Burnet, Kendall, Tom Green and Williamson counties, according to local officials. The death toll is certain to rise over the next few days, said Col. Freeman Martin of the Texas Department of Public Safety. The governor warned Sunday that additional rounds of heavy rains lasting into Tuesday could produce more life-threatening flooding, especially in places already saturated.
