As first responders continue to rescue people stranded by the torrential flooding that descended on central Texas Friday, dozens of people are facing a parent’s worst nightmare: Their children are missing.

Camp Mystic, on the banks of the Guadalupe River near Hunt, Texas, has been operated by generations of the same family since the 1930s.

Central Texas witnessed catastrophic flash floods. At least 52 people died. Richard Eastland, Camp Mystic's director, died a hero. He tried to save campers from rising floodwaters. Eastland and his wife managed the camp since 1974.
