Four days have passed since anyone was found alive in the aftermath of the floods in Kerr County, Texas, officials said Tuesday.

As search efforts entered their fifth day in the devastating Central Texas floods, Gov. Greg Abbott vowed to find "every single missing person," stressing that the mission will not end until all victims are accounted for amid a death toll that has surpassed 100.

A massive Texas search and cleanup effort was set to enter its fifth day Tuesday in response to Guadalupe River flooding that surged through the area on July 4.
