Flash floods that swept through Texas over the Fourth of July weekend have left more than 100 people dead and dozens of others missing.

Fifty-nine people are dead as a result of the flooding and torrential rains in Kerr County, Texas, Sheriff Larry Leitha said during a Sunday-morning press conference. That tally includes 38 adults and 21 children, Leitha said.

A massive Texas search and cleanup effort was set to enter its fifth day Tuesday in response to Guadalupe River flooding that surged through the area on July 4.
