At Camp Mystic, a Christian summer camp in Hunt, Texas, where officials are grieving the loss of 27 children and counselors, belongings of the young campers are strewn about the flooded floors of a dormitory, while other items, including a pink backpack and a Camp Mystic t-shirt, were found along the bloated Guadalupe River, photos show.

Matthew Gant said 14-year-old Mary Steele Gant was at Camp Mystic in central Texas when the camp was overwhelmed by flash flooding, WMC Action News 5 reported. Rain overwhelmed the Guadalupe River on July 4, causing it to rise as much as 26 feet in less than two hours.

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.
