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.

Brooklyn and Bailey MckNight's little sister, Paisley, was at a camp on a smaller arm of the Guadalupe River. The 14-year-old was "just miles" away from Camp Mystic in Central Texas, which has been devastated by the deadly floodwaters spurred by extreme rainfall on July 4.

Authorities said at least 24 people have died in flooding around Kerr County, Texas, and officials are still performing water rescues.
