Five campers and one counselor from Camp Mystic remain unaccounted for, officials say amid mounting questions over who was responsible for monitoring the weather.

Texas Gov. Greg Abbott said his state "will not stop until every missing person is found" following devastating flooding in central Texas over the Fourth of July weekend that left at least 104 dead. Ten young girls and a counselor from Camp Mystic in Hunt remain missing Tuesday.

Over 100 people have died after heavy rain pounded Kerr County, Texas, early Friday, leading to "catastrophic" flooding, the sheriff said.
