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

Torrential rains before dawn on Friday deluged the Guadalupe River, which burst its banks and killed dozens of people, leaving behind mangled piles of debris, trees and cars.

People gathered on Sunday along the roadsides and churches across Kerrville to mourn the loss of lives and pray for the ones still missing from the floods.
