One of the videos Paige shared showed many young girls sitting quietly in the back of a bus, being taken to a reunification center to meet their families. The girls were all singing worship songs during the ride, which Paige said was "to try and calm everyone."

'Devastating scenes'

Devon Paige wrote, "Camp Mystic on a bus to the reunification center. The girls are singing to try and calm everyone. This is footage from the evacuation and everything they saw. I wish you could see before shots to show how truly devastating it is."

850 people were rescued in the first 36 hours

Over 850 people were rescued in the first 36 hours after the flooding started. A sudden storm had dropped more than a foot of rain, which caused the Guadalupe River to overflow and rip through the camp’s historic buildings. Many campers and staff were swept away or trapped inside their bunks.

So far, 38 adults and 21 children have been confirmed dead. Eighteen of the adult victims and four of the children have not yet been identified. Among those who died were five girls from Camp Mystic, ages 8 and 9, as well as the camp’s owner, according to New York Post report.
