Camp Mystic, the all-girls summer camp on the banks of the Guadalupe River in Texas, has confirmed that 27 children and counselors died in the flash floods that have tore through the area since Friday.

Crews trudged through debris and waded into swollen riverbanks Monday in the search for victims of catastrophic flooding over the July Fourth weekend that killed more 80 people in Texas, including more than two dozen campers and counselors from an all-girls Christian camp.
