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

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.

Over 100 people have died after heavy rain pounded Kerr County, Texas, early Friday, leading to "catastrophic" flooding, the sheriff said.
