Flash floods surged through in the middle of the night, but many local officials appeared unaware of the unfolding catastrophe, initially leaving people near the river on their own.

Texas records show Camp Mystic had an emergency plan before floods killed at least 27 campers and counselors, but details of its storm response are still unclear.

Chloe Childress, a counselor at Camp Mystic, died during the flooding in Hunt, Texas, according to a representative of her high school.
