The crash took place around 7 p.m. Monday along Hwy. 114 in the Wise County town of Rhome. A tractor trailer heading east on Hwy. 114 slowed to turn into a private drive when an SUV slammed into the back of it, according to Texas DPS officials.
John Graham was driving that SUV with his kids, ages 6, 7 and 14, inside with him.
John was taken to John Peter Smith Hospital in Fort Worth, and his children were taken to Cook Children's Medical Center.
The children's mother, Jennifer Graham, updated the condition of her kids on her Facebook page.
Her 14-year-old son, Jacob, received the worst injuries -- severe facial injuries and several broken bones, as well as internal injuries.
One of her daughters has two broken legs and a partially-collapsed lung, while the other daughter has a broken arm.
Jennifer runs Champion Cheer, a well-known cheer gym in Southlake. Word of the crash quickly spread to the cheer teams and coaches across North Texas, along with cheer programs that have competed with them across the country.
Leslie Gordon says that the family feel of Champion Cheer and how welcomed she felt by Jennifer prompted her daughter to enroll.
But word that Jennifer's own family needed support left her and other cheer moms praying.
"It just broke my heart," said Gordon. "Jennifer is such a great lady. They really try hard to make this a family environment."
Ashlea Fritch cheered for Champion Cheer and now coaches. She's not surprised so many people are being supportive of the family as they recover -- paying it back when it's needed.
"They've impacted our lives so much, so to have something that's impacted their lives, it carries over to us to and it could happen to anybody," said Fritch.
