As hope for finding survivors dims, questions swirl around whether Camp Mystic's emergency plan was adequate. Texas doesn't approve or keep copies of such plans; camps are required to show only that they have plans in place.

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.

Over 100 people have died after heavy rain pounded Kerr County, Texas, early Friday, leading to "catastrophic" flooding, the sheriff said.
