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.

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

Gov. Abbott has ordered that flags be lowered to half-staff to honor those who lost their lives due to the floods.
