At least 120 people are dead from the devastating flooding in the Texas Hill Country. Kerr County was hit the hardest, with at least 95 deaths, including 36 children. President Donald Trump signed a disaster declaration for the county and the Federal Emergency Management Agency is on the ground there.

This week in Texas, estimates put the number of people still missing from the Hill Country floods at 161, a daunting figure atop at least 120 deaths confirmed by authorities. But that missing person tally might not be as precise as it seems.

Officials are being pressed about their response and whether there could have been a better warning system.

Search crews slogged through thick mud and debris Tuesday in central Texas, where more than 100 people are confirmed dead after catastrophic flooding. Pressure is growing on local officials to explain why more weren’t warned in time to escape.
