CBS News' Jason Allen has more on Kerr County's emergency alert system as more questions emerge about how Texans were notified ahead of the deadly floods.

Kerr County

Kerr County's code red emergency alert system, designed to warn residents of life-threatening situations, has come under scrutiny after several people reported not receiving alerts during recent severe flooding. John David Trollinger, a former county IT director involved in installing the system, stated he did not receive an alert until nearly six hours after the flooding began, despite being registered.

Local officials, including the Kerr County Sheriff, have declined to comment on the system's deployment during the storm, but acknowledged the need for answers. Meanwhile, stories of resilience have emerged, such as the Robertson family, who did not receive alerts but survived the flood and were later reunited after being rescued. The incident has prompted renewed discussion about the reliability of emergency notification systems in the area.

What we know about Texas floods emergency alerts

Now Kerr County's code red alerts are meant to warn people about emergencies, but some didn't receive one until hours into the flood response. CBS News correspondent Jason Allen spoke to the man who helped install the system. He joins us now from Kerr Vault. Jason. Good morning, Errol. Yeah, radio is a hobby for him, and so he was awake and he was listening to some of these emergency transmissions that were going out on the night of the storm. He shared these with us because of what he heard. He heard first responders out here on the river. They were risking their lives, and he really felt like people here as well should have had more warning. Yeah, so this is my radio shack. Wow. With rows of monitors in his office and antennas sticking out of his lawn and on his roof, John David Trollinger, a former Kerr County IT director and registered pilot, tracks everything from weather satellites to radio traffic. Around 1 a.m. the morning of the storm, he took note of National Weather Service alerts in the area. I looked, and oh, it's all red. Just before 3.30 a.m., he heard a firefighter warn the swelling Guadalupe River was cutting off roads. A little less than an hour later, a more urgent call came through. Yes, ma'am. We still have water coming up. The Guadalupe Shoemaker sign is now underwater on Highway 39. Is there any way we can send the code red out to our residents asking them to find our ground or stay home? Smart guy. 10-4, stand by. We have to get that approved with our supervisor. Trollinger was part of the team that installed code red at the county level more than a decade ago. It sends recorded messages and texts to warn people about life-threatening emergencies. Are you registered on code red? Yes. Did you get an alert that night? No. He says he didn't receive an alert for nearly six hours. Wednesday, the Kerr County Sheriff declined to comment on how the code red system was deployed during the storm. Those questions are going to be answered. I believe those questions need to be answered to the family of the misled ones, to the public, you know, to the people that put me in this office. As the community mourns, there have been remarkable stories of resilience. Mom, are you in a tree? 15-year-old Jack Robertson recorded this on his phone, yelling to his mother, Lindsay, as they both clung to treetops just barely above the churning floodwaters Friday. This big dead tree with the telephone pole holding it up, that's the tree my mom was in. After the waters receded, Lindsay's husband, Philip Robertson, found her with a neighbor who had patched up a large gash on her leg. People immediately started pitching in and helping and it hadn't stopped yet. I mean, I think I was telling you earlier, it's renewed my faith in humanity. The Robertson family told us it didn't receive any alerts ahead of the storm. Lindsay is recovering in the hospital where she was being treated for injuries to her leg. And the couple also had a couple daughters who were up at that heavily impacted Camp Mystic. They were staying there with their cousins. They are okay. Helicopters evacuated them, Errol, and they are all reunited this morning.
