What had started out as a desperate rescue operation had by now morphed into a plodding, methodical one of recovery. The last person to be rescued alive was found Friday, Kerrville Police Department Community Services Officer Jonathan Lamb said Tuesday.

The officers "realized that areas of town that traditionally don't flood were going to flood, and that low-lying areas close to the river were in danger," Kerrville police community services officer Jonathan Lamb said at a news conference on Wednesday.

Over 100 people have died after heavy rain pounded Kerr County, Texas, early Friday, leading to "catastrophic" flooding, the sheriff said.

In the early hours of July 4, the only sound many of the vacationers along the banks of the Guadalupe River would have heard was pounding rain and thunder. They didn’t get any official warning of the rapidly rising waters that ultimately proved deadly to dozens of people swept away in central Texas flash floods.
