Texas Gov. Greg Abbott visited the all-girls retreat Camp Mystic late Saturday as the death toll from Friday's flash flooding of the Guadalupe River continued to rise through the weekend.

81 people have been confirmed dead throughout the state. In Kerr County, which is where Camp Mystic and other youth camps in the Texas Hill Country are based, searchers have found the bodies of 68 people, including 28 children, Sheriff Larry Leitha said. Camp Mystic confirmed to NBC News that 27 people had died at the camp.
