Search crews continued the grueling task of recovering the missing as more potential flash flooding threatened Texas Hill Country.

The Texas Department of Juvenile Justice said a West Texas juvenile probation officer was among the victims of deadly Kerr County flooding that happened over the July 4 weekend.

Recordings provided to CBS News showed first responders asking for an emergency alert to be sent, but dispatchers delayed because they needed special authorization.

The reporter said that several families were angry because they felt that alerts for the flood did not go out in time.

Eight-year-old girls at sleep-away camp, families crammed into recreational vehicles, local residents traveling to or from work. These are some of the victims.

A memorial service was held in Kerr County, Texas on Friday to honor the victims and those still missing from flooding that recently struck the region.

Officials in Kerr County, where the majority of the deaths from the July 4 flash floods occurred, have yet to detail what actions they took in the early hours of the disaster.

President Donald Trump travels to Texas on Friday amid growing questions about how local officials responded to the devastating floods, as well as questions about the federal response -- including FEMA's fate -- that he has so far avoided.
