The search for the missing continues in Texas following a holiday weekend deluge that killed at least 82 people.

Search teams plodded through mud-laden riverbanks and flew aircraft over the flood-stricken landscape of central Texas for a fourth day on Monday, looking for dozens of people still missing from a disaster that has claimed at least 78 lives.

Although Kerr County was hit hardest by flooding, at least seven others have been confirmed dead in different parts of Texas. About 150 miles east of Camp Mystic, Travis County has confirmed at least six deaths, the county confirmed Sunday. Travis County includes the Texas capital city of Austin.
