In the Austin area, 12 people are still missing and 16 are known to have perished after rain swept away homes along rivers and creeks.

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.

Officials in Kerr County, which was hit by the flood the hardest, admitted during a news conference that no one has been found alive in the county since Friday.
