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.

As the floodwaters rushed into Kerrville, Texas, under the cover of darkness on Friday morning, officers jumped into action to evacuate over 100 homes and rescue more than 200 people in one hour, the police department said.
