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.

KERRVILLE, Texas (AP) — Hope of finding survivors of the catastrophic flooding in Texas dimmed Tuesday, a day after the death toll surpassed 100, and crews kept up the search for people missing in the aftermath.

Rescuers searched the Guadalupe River for survivors of the Texas floods that killed more than 100 people over the July Fourth holiday weekend, with an unknown number of people still missing. The basin area was crowded with families and campers preparing to enjoy the holiday when pounding rain brought about catastrophic flash floods just before dawn Friday.

The family of Sally Sample Graves is mourning the loss of their beloved 91-year-old matriarch, who died in the devastating flash floods that swept through the Texas Hill Country.
