“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 Hill, a mother whose story went viral after her three-year-old son Colton suffered a broken femur in a “little jumpers” session. We share this because, in City of Mineral Wells, we know families are looking for safe ways to let their children burn off energy, whether it is at a backyard Jumpking or a weekend trip to a major adventure park in the DFW metroplex. But what Kati Hill told ABC News is a reality we see far too often: “We had no idea. We would have never put our baby boy on a trampoline if we would have known.”

If you are reading this at a hospital bedside or in the quiet of your home in City of Mineral Wells while your child recovers from a catastrophic landing, you need to understand one thing immediately: what happened wasn’t a “freak accident.” It was the predictable output of a business model that prioritizes throughput and margin over the safety of your family. In Harris County, a jury recently sent a message to this industry by awarding $11.485 million against the operator of Cosmic Jump after a teenager fell through a torn trampoline slide onto concrete. The waiver was signed. The park argued the risk was inherent. The jury found gross negligence anyway.

At Attorney911, led by Ralph Manginello with over 25 years of trial experience, we don’t just “handle” these cases. We dismantle the industry’s defenses. We are currently litigating a $10 million lawsuit against a major university involving rhabdomyolysis and acute kidney failure—the exact same muscle and organ breakdown we see in children who jump past the point of exhaustion in overheated indoor parks. Our team includes a former insurance defense attorney, Lupe Peña, who used to write the very waivers these parks use to try and silence you. He knows where the holes are. He knows how to beat them.

The Evidence Clock in City of Mineral Wells: Why You Have Seven Days

The most important thing to know right now is that the evidence of what happened to your child is already disappearing. Trampoline park surveillance systems in the regions serving City of Mineral Wells, such as those in nearby Hudson Oaks or Fort Worth, typically operate on a 7-to-30-day overwrite cycle. If we do not send a formal spoliation letter within days of the injury, that footage is gone forever.

We don’t wait for the insurance company to “do the right thing.” We know that by day ten, the DVR has likely overwritten the moment of impact. By day twenty, the teenage attendant who was on his phone instead of watching the court has moved to a different job. By day thirty, the “updated” incident report is the only version the park will admit exists. We send our preservation demands within 24 hours of being retained. We demand the native video files, the kiosk audit logs, the maintenance records, and the internal staffing schedules. In City of Mineral Wells, your family deserves a firm that treats your case with the urgency it demands.

Why Trampoline Injuries Are Never Just “Accidents”

When a child in City of Mineral Wells is launched by a “double-bounce,” the physics are devastating. When a 200-pound adult lands on a trampoline bed at the same instant a 60-pound child is pushing off, the energy transfer can multiply the child’s launch force by up to 4x. The child is no longer jumping; they are a projectile.

The industry knows this. The American Academy of Pediatrics (AAP) has been warning parents since 1999 that trampolines do not belong in homes. The industry itself drafted ASTM F2970 as a voluntary safety floor, but as we see in parks across North Central Texas, those standards—covering attendant ratios, age separation, and foam pit maintenance—are the first things to be sacrificed when the park is crowded on a Saturday afternoon.

If your child was injured in a foam pit, understand that the industry has been moving toward airbags since 2018 precisely because foam pits are death traps for the cervical spine. When foam cubes are not rotated or replaced, they compact. A child dived or falling into a compacted pit hits the hard floor beneath with their head and neck. We cite EN ISO 23659:2022—the mandatory international standard—to show that what American parks call “industry standard” is actually a sub-par environment that most of the developed world has already banned.

Texas Law and the Paper Shield: Tearing Down the Waiver

They told you that because you signed a waiver at the kiosk, you have no right to sue. In City of Mineral Wells, and throughout the State of Texas, that is one of the biggest lies told to families. Texas law, specifically the landmark ruling in Munoz v. II Jaz, Inc., makes it clear: a parent generally cannot sign away a minor child’s right to sue for personal injuries. Your signature might affect your own claims, but it does not strip your child of their right to recovery.

Furthermore, the Texas “fair notice” doctrine established in Dresser Industries v. Page Petroleum requires that any release of negligence be specific and conspicuous. Most kiosk waivers, buried in 20 screens of digital click-throughs, fail this test. And as the $11.485 million Cosmic Jump verdict proves, no waiver in Texas can protect a defendant from their own gross negligence—the conscious indifference to a known, extreme risk.

Our associate, Lupe Peña, uses his background in insurance defense to identify exactly where these waivers fail. Whether it is a bilingual-formation issue under the Delfingen doctrine for our Spanish-speaking families in Palo Pinto County, or a signer-authority failure under Texas Family Code § 153.073, we find the path to court.

Catastrophic Injuries: The Medicine Your Family Is Facing

We represent the parent at the trauma-bay bedside. We represent the child whose life changed in a single landing. In City of Mineral Wells, major injuries often route to Cook Children’s Medical Center in Fort Worth, where surgeons deal with the “trampoline fracture”—a classic proximal tibial metaphyseal buckle fracture.

But the injuries can be much worse. We represent families dealing with:

  • Salter-Harris Growth Plate Fractures: A fracture at age nine that may not show its true damage until age fourteen, when one leg stops growing straight because the growth plate was destroyed.
  • SCIWORA: Spinal Cord Injury Without Radiographic Abnormality. A child can have a “normal” CT scan in the ER but be suffering from cord ischemia that leads to permanent paralysis.
  • Vertebral Artery Dissection: As seen in the viral Elle Yona case, a backflip can tear the artery in the neck, leading to a spinal cord stroke. These are often misdiagnosed as panic attacks in the ER.
  • Exertional Rhabdomyolysis: If your child has dark, cola-colored urine after a long day at the park, their muscles are breaking down and poisoning their kidneys. This is a medical emergency we understand deeply through our active $10 million University of Houston litigation.

The 5-Layer Defendant Stack: Who Actually Pays for the Injury?

The local LLC running the park is often undercapitalized by design. They want you to think their $1 million policy is the only money available. We know better. We go upstream, every time.

We investigate the 5-Layer Defendant Stack:

  1. The Operator LLC (the local park).
  2. The Franchisee (the owner of multiple locations).
  3. The Franchisor (entities like Sky Zone Franchising LLC or Urban Air Franchise Holdings).
  4. The Corporate Parent (Sky Zone, Inc., Unleashed Brands).
  5. The Private Equity Sponsor (Palladium Equity Partners, Seidler Equity Partners).

The money is upstream. We’ve gone head-to-head with corporate giants like BP, Walmart, and Amazon. The parent conglomerates behind national trampoline park chains don’t intimidate us. We identify every insurance layer—primary, umbrella, excess, and additional insured layers—to ensure your child’s recovery fund is fully funded.

Backyard Trampolines in City of Mineral Wells: Attractive Nuisance

In the neighborhoods of City of Mineral Wells, the backyard trampoline is as common as the oak tree. But in Texas, an unfenced or unsecured trampoline is an “attractive nuisance.” If a neighbor’s child wanders onto your property and is injured, the doctrine holds you accountable for failing to secure a foreseeable hazard. Conversely, if your child was the one injured, we know how to navigate the complex web of homeowner’s insurance exclusions and manufacturer defects.

Manufacturers like Jumpking, Skywalker, and Bouncepro have documented recall histories. From frame welds that snap to enclosure nets that fail under UV exposure, we hold the manufacturers accountable for failing to meet ASTM F381 standards.

How We Build Your Case in Palo Pinto County

Building a multi-million-dollar trampoline case is an engineering project. We don’t just file papers; we deploy a system:

  1. Immediate Spoliation: 24-hour delivery of the litigation hold.
  2. Scene Investigation: Deploying biomechanical engineers to model the energy transfer of the impact.
  3. Digital Forensics: Using tools like FTK Imager and Cellebrite to recover “glitched” video or revised incident reports.
  4. Pediatric Medical Experts: Retaining top surgeons and physiatrists to project the 50-year lifetime cost of your child’s care.
  5. Forensic Economists: Quantifying the loss of future earning capacity for a child whose career path has been permanently altered.

Frequently Asked Questions for City of Mineral Wells Parents

Can I sue if I signed the waiver at an Urban Air or Sky Zone?
Yes. In Texas, a parent’s signature generally cannot waive a minor’s personal cause of action. Additionally, no waiver protects a park from gross negligence or reckless disregard for safety standards like ASTM F2970.

How long do I have to sue a trampoline park in Texas?
While the personal injury statute of limitations is two years, the clock for a minor is tolled until they turn 18. However, the evidence clock is only 7 to 30 days. If you wait, the surveillance footage and witness memories will be gone.

What is a Salter-Harris fracture and why is it serious?
It is a fracture through the growth plate. In a growing child in City of Mineral Wells, this can cause the bone to grow crooked or stop growing entirely, requiring surgeries years down the line.

What if the park manager told me not to call 911?
This is a documented industry tactic to downplay injuries and prevent official records. If a park discourages 911, it is evidence of a culture of concealment that we use to prove gross negligence.

Should I take the medical-payment check the insurance company offered?
No. This is often a “Med-Pay” trap. Signing the back of that check may release the park from all future liability. Never sign a release or deposit a check from the park’s insurer without a lawyer reading the fine print.

Is it the park’s fault if another kid landed on mine?
Yes. The park has a non-delegable duty to supervise and enforce one-jumper-per-bed rules. They cannot outsource their safety obligations to a seven-year-old child.

What if the waiver was only in English and we speak Spanish?
Under the Delfingen doctrine, a waiver signed by someone who cannot read the language of the contract may be void. Lupe Peña speaks Spanish natively and represents our Spanish-speaking families directly.
