Over the July 4th weekend, deadly flash floods swept through Kerrville, Texas, after a month’s worth of rain fell in just hours, causing the Guadalupe River to rise 26 feet. More than 100 people have died, with many still missing. Among the victims were 13-year-old Blair and 11-year-old Brooke Harber, who were staying with their grandparents, Mike and Charlene, along the river.

Their aunt, Jennifer Harber, confirmed the girls were found 15 miles away, still holding hands. Their grandparents remain missing.
