A July Fourth weekend deluge in Texas caused catastrophic flash flooding that has killed more than 80 people. Camp Mystic in Kerr County says Monday morning that it is “grieving the loss” of 27 campers and counselors as the search continues for victims of the disaster.

Several days after devastating floods killed at least 100 across Central Texas, 10 campers and one counselor remain unaccounted for from Camp Mystic, officials said during a press conference.

Residents of Kerr County began clearing mud and salvaging what they could from their demolished properties as they recounted harrowing escapes from rapidly rising floodwaters.
