The death toll from the July Fourth flash flood that ravaged a swath of central Texas Hill Country rose on Tuesday to at least 109, many of them children, as search teams pressed on through mounds of mud-encrusted debris looking for scores of people still missing.

Search and rescue operations in Texas continue after heavy rainfall overwhelmed the Guadalupe River, sending floodwaters roaring through the area.

Kerr County officials say they are still focused mainly on the search for survivors with hundreds still missing and weren’t yet examining how the emergency response unfolded.

The Guadalupe River has a history of terrible, fatal floods. The flash floods that killed at least 100 people in central Texas last week is only the latest disaster to claim lives.

Texas inspectors approved Camp Mystic’s emergency plan just two days before devastating floods killed over 27 people, mostly children, at the Texas summer camp
