At a Wednesday morning press conference, Kerr County Sheriff Larry Leitha declined to answer a question about delayed emergency alerts, saying that an "after-action" would follow the search and rescue efforts. "Those questions are gonna be answered," he added.

Posts claimed the 42-year-old man rescued at least nine elderly residents trapped in a retirement complex amid flooding in Kerr County, Texas.

Nearly a week after deadly floods struck Central Texas, search and rescue teams are continuing to probe debris for those still missing.

Crews are using construction equipment to clear vehicles, trees and homes in a race to locate the 161 people still missing since Friday’s devastating flood.

FOX 4’s Steven Dial rode along the Guadalupe River with the sheriff of Andrews County, located in West Texas, to get his first-hand account of the recovery effort.

As the Guadalupe River swelled from a wall of water heading downstream, sirens blared over the tiny river community of Comfort -- a last-ditch warning to get out for those who had missed cellphone alerts and firefighters going street-to-street telling people to get out.

A Kerrville-area river authority executed a contract for a flood warning system that would have been used to help with emergency response, local officials said.
