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.

An eight-year-old girl and the director of an all-girls' summer camp are among the victims of flash floods in Texas that have claimed at least 51 lives, including 15 children. Officials say most of the victims have been identified. Authorities have not yet released any names publicly.
