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.

At Camp Mystic, a Christian summer camp in Hunt, Texas, where officials are grieving the loss of 27 children and counselors, belongings of the young campers are strewn about the flooded floors of a dormitory, while other items, including a pink backpack and a Camp Mystic t-shirt, were found along the bloated Guadalupe River, photos show.

Kerr County, Texas and national search and rescue operations will continue Monday around the Guadalupe River, where families wait for news of their loved ones.

The National Weather Service began sending flash flood warnings that should have triggered cellphone alerts a little after 1 a.m., while local officials began posting on Facebook about four hours later.
