Texas Gov. Greg Abbott on Wednesday ordered state legislators to convene a special session on Monday as the death toll rose to at least 120 people and 172 reported missing in Fourth of July flooding in the Hill Country.

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 warned that the full extent of the catastrophe is unknown and unaccounted victims could still be found amid the massive piles of debris.
