Officials in Texas are facing mounting questions about whether they did enough to get people out of harm's way before a flash flood swept down the Guadalupe River and killed more than 100 people, including 27 children and counselors at an all-girls Christian camp.

Gov. Greg Abbott revealed late Tuesday that at least 173 people remained missing — the first time state officials have identified just how widespread the human toll might eventually be.

As families and search crews sift through debris, mangled trees and toppled vehicles in Kerr County after the catastrophic Fourth of July flooding, authorities are facing growing questions about whether enough warnings were issued.

At least 95 people have died in Kerr County, Texas, according to officials, after devastating flash floods swept through south central Texas on Friday, killing 119 people in the state.
