The death toll in Kerr County crept up to 87 on Tuesday as search and rescue efforts continued in flood-ravaged central Texas, according to officials in the county worst hit by the disaster, which has killed more than 100 people.

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 105 dead. Five young girls and a counselor from Camp Mystic in Hunt remain missing Tuesday.

A massive Texas search and cleanup effort was set to enter its fifth day Tuesday in response to Guadalupe River flooding that surged through the area on July 4.
