"His feet hit the mat, and almost instantly his knees buckled down, and he just let out the worst scream that you could ever have heard from a child." That is Kaitlin "Kati" Hill, a mother whose warning post about a trampoline park injury to her three-year-old son, Colton, was shared over 240,000 times on social media. As she told ABC News, "We had no idea. We would have never put our baby boy on a trampoline if we would have known." At Attorney911, we hear the echo of that scream in nearly every case we handle. Whether it happened at a commercial park along the I-35W corridor or in a backyard in a neighborhood near Justin Road, the story is often the same: a family went out for fun in the Town of Northlake and came home with a catastrophic medical crisis. We’ve seen what happens when the laughter stops. We’ve represented the parents standing in the trauma bay at Cook Children’s Medical Center or Children's Medical Center Dallas, watching a surgeon explain that a child’s skeletal future has been altered in a single bounce. For over 25 years, our founder Ralph Manginello has fought for victims of life-altering…

"His feet hit the mat, and almost instantly his knees buckled down, and he just let out the worst scream that you could ever have heard from a child." For Kaitlin "Kati" Hill, a mother whose three-year-old son Colton suffered a broken femur and a body cast after a trampoline park visit, those words haunt every night.

That is the voice of Kaitlin "Kati" Hill, a mother whose three-year-old son sustained a broken femur in a body cast after a visit to a trampoline park. She later told ABC News, "We had no idea. We would have never put our baby boy on a trampoline if we would have known." For families in Hickory Creek, Texas, a weekend trip to a trampoline park or a birthday party in a neighbor’s backyard is supposed to be about laughter and exercise.

Town of Hackberry Trampoline Injury Guide: Accountability for Texas Families One moment, your son was launching toward a basketball rim at a park near Town of Hackberry.

"His feet hit the mat, and almost instantly his knees buckled down, and he just let out the worst scream that you could ever have heard from a child." That was Kaitlin "Kati" Hill, a mother whose account of her three-year-old son’s broken femur was shared a quarter of a million times on social media. It is a scream we have heard variations of for over twenty-five years. It is a scream that echoes through the quiet suburban streets of Town of Double Oak when a backyard playdate goes wrong, and it is the same scream that pierces the loud, neon-lit atmosphere of trampoline parks across Denton County.

That is Kaitlin Hill, the mother of three-year-old Colton, telling ABC News what happened the day a trampoline park broke her son’s femur. Her warning post was shared 240,000 times. We read it.

"His feet hit the mat, and almost instantly his knees buckled down, and he just let out the worst scream that you could ever have heard from a child." That is how Kati Hill described the moment her three-year-old son Colton’s life changed at a foam-pit-and-trampoline facility. Her warning, shared more than 240,000 times on social media, ends with a phrase we hear in nearly every intake call at our firm: "We had no idea." If you are reading this in a waiting room at Cook Children’s in Prosper or near the trauma bay at Children’s Medical Center in Dallas because your child was injured at a facility near Town of Cross Roads, we want you to know three things immediately. First, this is not your fault. You signed a waiver at a kiosk because the line was long and you wanted your child to have fun. You did not consent to the park’s failure to follow safety standards. Second, the "temporary" injury you are looking at might have lifelong orthopedic or neurological consequences that the park’s insurance adjuster is already trying to minimize. Third, the evidence that will prove what actually happened—the surveillance video and the digital logs—starts overwriting…

The double-bounce happened in two seconds. You were watching from the observation rail at the trampoline park in Denton County, just a short drive from Town of Corral City, and then your world shifted.

On any given Saturday afternoon, families from the Town of Copper Canyon travel just a few miles south or east to the massive entertainment hubs in Southlake, Denton, or Frisco. You might be at the Urban Air in Southlake—the flagship location where the entire franchise began—or perhaps the Altitude in Fort Worth Keller. You signed the waiver at the kiosk because the line was long and your children were vibrating with excitement. You handed them their grip socks, told them to have fun, and found a seat at the observation rail. Then, the scream happens. As Kaitlin "Kati" Hill told ABC News after her son Colton’s femur was shattered at a park, it is "the worst scream that you could ever have heard from a child." In that split second, your life in the Town of Copper Canyon changes. The park manager approaches not with a medical kit or an ambulance on speed dial, but with a clipboard and a "guest error" form. You are told the injury was an "inherent risk." You are reminded that you signed a waiver. At the emergency room at Cook Children’s or a trauma bay in Denton, the surgeon explains that your child has…
