At least 68 deaths—including the deaths of 21 children—have now been confirmed in the central Texas flash floods, according to the latest update from officials, though dozens of children from a summer camp remain unaccounted for as blame swirls over preparedness and whether residents were properly alerted.

Kerr County has reported 28 adults and 15 children deceased, Travis County has counted four deaths, Kendall and Tom Green counties have confirmed one each, and the Burnet County Emergency Management coordinator said in a statement that two fatalities have been confirmed Saturday.

Anguished parents waited for word on the more than two dozen children still missing from Camp Mystic, a Christian girls' camp.
