Officials in Texas are facing mounting questions about whether they did enough to get people out of harm’s way before a flash flood swept down the Guadalupe River and killed more than 100 people, including at least 27 children and counselors at an all-girls Christian camp.

Rescue efforts include more than 2,100 responders on the ground, private helicopters, drones, boats and cadaver-detecting dogs.
