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 at least 27 children and counselors at an all-girls Christian camp.

Texas Governor Greg Abbott said Tuesday that many of those who are not accounted for were staying in state’s Hill Country but did not register at a camp or hotel.

More than 100 people were killed and over 160 remained missing as of Tuesday evening after flooding hit Central Texas.

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

KERRVILLE, Texas (AP) — Hope of finding survivors of the catastrophic flooding in Texas dimmed Tuesday, a day after the death toll surpassed 100, and crews kept up the search for people missing in the aftermath.

Rescuers searched the Guadalupe River for survivors of the Texas floods that killed more than 100 people over the July Fourth holiday weekend, with an unknown number of people still missing. The basin area was crowded with families and campers preparing to enjoy the holiday when pounding rain brought about catastrophic flash floods just before dawn Friday.
