HUNT, Texas — Crews used backhoes and their bare hands Wednesday to dig through piles of debris that stretched for miles in the search for more than 160 people believed to be missing in the flash floods that laid waste to the Hill Country region of Texas.
Over 100 bodies have been recovered, but the large number of missing suggested that the full extent of the catastrophe was still unclear five days after the disaster.
''We will not stop until every missing person is accounted for,'' Gov. Greg Abbott told a news conference Tuesday. "Know this also: There very likely could be more added to that list.''
Officials have been seeking more information about those who were in the popular tourist destination during the Fourth of July holiday weekend but did not register at a camp or a hotel and may have been in the area without many people knowing, the governor said.
The riverbanks and hills of Kerr County along the Guadalupe River, where most of the flood victims have been recovered so far, are filled with vacation cabins, youth camps and campgrounds, including Camp Mystic, the century-old all-girls Christian summer camp where at least 27 campers and counselors died. Officials said five campers and one counselor have still not been found.
Crews in air boats and helicopters and on horseback combed the terrain. They also used excavators and their hands, going through the earth layer by layer, with search dogs sniffing for any sign of buried bodies.
They were joined by hundreds of volunteers in one of the largest search operations in Texas history. The search has been slow, made more difficult by ongoing storms and dense layers of tangled trees and rubble.
The flash flood was the deadliest from inland flooding in the U.S. since Colorado's Big Thompson Canyon flood on July 31, 1976, killed 144 people, said Bob Henson, a meteorologist with Yale Climate Connections. That flood surged through a narrow canyon packed with people on a holiday weekend marking Colorado's centennial.
