Texas parents frantically posted photos of their young daughters on social media with pleas for information as at least 27 campers from an all-girls summer camp were unaccounted for Friday after floods tore through central Texas overnight. At least 37 people, including 14 children, are dead after a storm unleashed nearly a foot of rain just before dawn Friday and sent floodwaters gushing out of the Guadalupe River through the region known for its century-old summer camps. State officials said 27 girls from Camp Mystic, a riverside Christian camp in Hunt, Texas, still were unaccounted for.
