At least 120 people have been found dead since heavy rainfall overwhelmed the river and flowed through homes and youth camps in the early morning hours of July 4. Ninety-six of those killed were in the hardest-hit county in central Texas, Kerr County, where the toll includes at least 36 children.

A total of 121 people have died in the floods and 170 people are missing, most in Kerr County. As Karen Hua reports, officials there have been pressed to explain why a code red alert went out late.
