Texas officials are facing mounting questions about when Kerrville's residents were notified about deadly flash floods that killed 96 locals, with over 160 others still missing.
Asked about a possible police radio failure at a press conference on Thursday - almost a week after 4 July flooding - Kerrville Police community services officer Jonathan Lamb said, "I don't have any information to that point."
The questioning followed a tense exchange the day before when reporters asked officials repeatedly about a possible lag in emergency communications.
Early Friday, the Guadalupe River rose several metres in a matter of minutes, after an estimated 100bn gallons of rain.
At least 120 people have died in the Texas Hill Country flash floods. Kerr County, which includes Kerrville, absorbed the brunt of the devastation, with 96 confirmed deaths, including 36 children, many of whom attended a nearby Christian camp.
