HUNT, Texas (AP) — Crews used backhoes and their bare hands Wednesday to dig through piles of debris that stretched for miles in the search for more than 160 people believed to be missing in the flash floods that laid waste to state’s Hill Country.

The Associated Press has assembled an approximate timeline of the 48 hours before, during and after the deadly flash flood, beginning with the activation of the state’s emergency response resources on July 2 — the same day Texas signed off on the camp’s emergency plan for disasters.

Texas Governor Greg Abbott says at least 109 people are dead and 161 people are still missing due to the catastrophic flooding that ravaged the Texas Hill Country. Kerr County officials were pressed today over why there is no county-wide siren system to warn people about natural disasters like flash flooding.
