Two sisters who died in the Texas flood disaster were found with their hands “locked together,” according to family.

Brooke and Blair Harber, ages 11 and 13, were staying with their grandparents along the Guadalupe River when the floodwaters inundated their neighborhood in Hunt on the morning of Friday, July 4, according to NBC affiliate KXAS-TV and CBS affiliate KTVT.

In a statement shared on GoFundMe, the girls’ aunt Jennifer Harber said the girls’ parents, RJ and Annie, went to check on the girls and their grandparents, Mike and Charlene, around 3:30 a.m. local time. But the water was too high to reach where the four were staying.

Around the same time, Jennifer said Brooke texted “I love you” to her grandparents. She and Blair were later found dead 15 miles away in Kerrville.

“When they were found, their hands were locked together,” the aunt explained.

Brooke and Blair were students at St. Rita Catholic School in Dallas, according to KXAS-TV and KTVT.

In a statement, school officials said Brooke was about to enter 6th grade and Blair was about to enter 8th grade. They described the girls as “young women of deep faith” and “went to the loft of their cabin with their rosaries” when the flooding occurred.
