A new report has found that officials in Kerr County, Texas, did not use technology that would have sent lifesaving emergency messages to everyone in the vicinity of the Guadalupe River as it flood 4.

CBS News analysis shows there were 22 warnings sent by the National Weather Service for Kerr County and the Kerrville area, but many residents say they didn't get alerts.

Government warnings reach mobile devices through partnerships between FEMA, FCC and carriers like Verizon and AT&T, as shown in Texas flooding.

Officials at the Comfort Volunteer Fire Department triggered a flood warning siren last week when the Guadalupe River began to swell.

Weather warnings predicted devastation from both the Texas floods and Hurricane Helene. But in both disasters, people were left in harm’s way.

Rep. Chip Roy (R-Texas) said Sunday the “real story” of the deadly flooding in Texas is the “heroism of those who showed up” to help, as opposed to who might be to blame. “I think the real story is not all the finger-pointing that the media wants to point to.

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.

Kerr County Sheriff Larry Leitha was unable to answer direct questions about who was in charge and whether they were asleep early Friday morning when the Guadalupe River burst its banks.
