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.

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.

Greg Abbott is directing lawmakers returning to Austin this month to improve early warning systems and emergency communication in flood-prone areas and redraw the state's congressional districts in an effort to bolster Republicans in the midterms.
