At least 67 people are dead after heavy rain lashed Texas, leading to "catastrophic" flooding. Texas Gov. Greg Abbott said emergency responders remained in a search and rescue posture, hours after the flooding along the Guadalupe River inundated nearby areas.

As of early Monday, 81 people died across six counties. Sixty-eight died in Kerr County alone, 40 were adults and 21 were children. Authorities said about 850 people had been rescued or evacuated. There are still 10 Mystic Camp campers and one camp counselor missing.

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 four deaths, county spokesperson Hector Nieto told CBS News by phone Saturday night. Travis County includes the Texas capital city of Austin.
