The Worst Scream: A Warning for Every Parent in City of Blue Mound
Our firm knows the sound. It is a sound that breaks the air in North Fort Worth hospitals like Cook Children’s Medical Center and Texas Children’s daily. It is “the worst scream that you could ever have heard from a child,” as Texas mother Kati Hill described it to ABC News after her three-year-old son, Colton, suffered a broken femur during a “Toddler Time” session at a trampoline park. Kati, like so many parents in City of Blue Mound, had no idea. She believed the marketing. She believed that because the park had a designated time for small children, the staff was trained and the environment was safe. Today, Colton is a survivor, but his story—and the hundreds of others we have documented—remains a terrifying reminder of what happens when a business decision to cut costs meets the brutal physics of a trampoline bed.
We are Attorney911, led by managing partner Ralph Manginello. For over 25 years, our firm has stood in the gap for families facing catastrophic, life-altering injuries. We have litigated against multinational corporations like BP and retail giants like Walmart. We are currently pursuing a $10 million lawsuit against the University of Houston regarding rhabdomyolysis and acute kidney failure—the exact physiological trauma we see in children who spend extended hours jumping in the humid, overheated facilities that dot the Tarrant County landscape.
If you are reading this at a hospital bedside tonight, or if you just came home to City of Blue Mound with a discharge packet for a child who may never walk the same way again, you likely have been told that because you signed a waiver at a kiosk, you have no case. We are here to tell you that the insurance adjuster is wrong. That piece of paper is a tool designed to discourage you, not the final word on your child’s future. Between the Tarrant County courthouse and our offices in Houston, Austin, and Beaumont, we have spent decades dismantling corporate shields. We know which waivers are full of holes, and we know how to hold the multibillion-party conglomerates behind Sky Zone, Urban Air, and Altitude accountable.
What happened to your child in City of Blue Mound was not an accident. It was the predictable output of a system designed to maximize jumper-hours and minimize labor costs. Our job is to prove it.
The Data the Trampoline Industry Doesn’t Want You to Read
When you drive along I-35W or Loop 820 with your kids, you see the massive signs for Urban Air and Sky Zone. They look like colorful beacons of family fun. But the property and casualty insurance market sees them differently. Major insurers like Philadelphia Insurance Companies have largely exited the trampoline park segment because the loss ratios are uninsurable. The risk of a “nuclear verdict”—a multi-million dollar award for a single injury—is simply too high.
The data supports their fear. According to a landmark study by Teague et al., published in the American Academy of Pediatrics’ journal Pediatrics in January 2024, injury rates at trampoline parks are not just rising; they are becoming a documented pediatric trauma category. The study tracked over 13,256 injured trampoline-park users across 8.4 million jumper-hours. The findings were stark: the foam-pit and inflatable-bag injury rate was 1.91 per 1,000 jumper-hours, while “high-performance” jumping zones saw rates jump to 2.11 per 1,000.
In a metro as dense as the Dallas-Fort Worth area, the cumulative toll is devastating. A Fort Worth Star-Telegram investigation recently uncovered 500 injuries at 21 regional trampoline parks over a seven-year period. That is 500 families in our local communities who had to navigate surgeries, physical therapy, and the permanent alteration of their children’s lives. This matches a national trend reported by the Consumer Product Safety Commission (CPSC), which tracks approximately 300,000 trampoline-related ER visits annually across the United States. Furthermore, the American Journal of Roentgenology (AJR 2024) recently noted that up to 1.6% of all pediatric emergency department trauma visits are now trampoline-related.
This is not a “freak accident” problem. This is a public health crisis masquerading as recreation.
How Your Child Was Injured: The Physics and the Negligence
Most personal injury generalists in City of Blue Mound see a “broken leg” and think of a slip-and-fall. We don’t. We see a comminuted femoral shaft fracture or a Salter-Harris Type III growth plate injury, and we work backward to the physical mechanism of the breach.
The Double-Bounce: A Catapult for Children
The most common injury mechanism on a trampoline court is the “double-bounce.” This occurs when a heavier jumper—often an adult or a teenager—lands on the trampoline bed at the same instant a smaller child is pushing off. The energy transfer from the heavier mass to the lighter one is extraordinary. In City of Blue Mound backyards and commercial parks alike, we have seen this physics multiplier launch children with up to 4x the force of their own jump. The child isn’t just bouncing; they are being projected at velocities their developing musculoskeletal system cannot absorb on descent.
The Breach: ASTM F2970—the commercial safety standard the industry wrote about itself—requires parks to enforce age and weight separation. When an Urban Air or Sky Zone allows a 200-pound adult to share a court with a 6-year-old from City of Blue Mound, they are making a conscious decision to ignore the physics they were warned about. This is gross negligence.
The Foam Pit Illusion
The foam pit at a North Fort Worth park looks like a soft cloud. In reality, it is often a trap. The mechanism of injury here is “bottoming out” or axial loading. If the foam cubes have compressed over time (a common failure of maintenance to save on replacement costs), or if the pit depth is below the ASTM F2970 requirement, a child landing head-first or feet-first will strike the hard concrete subfloor beneath.
The Breach: We have documented cases where foam pits were only 2 to 3 feet deep despite recommendations of 6 feet or more. A child who lands head-first in a shallow pit faces an immediate risk of cervical hyperflexion and a spinal cord injury known in pediatrics as SCIWORA—Spinal Cord Injury Without Radiographic Abnormality. The child may have a “normal” CT scan in a Fort Worth ER, but their cord is dying because of the shear force.
Mechanical Failures at Adjacent Attractions
Parks in our area have pivoted to the Family Entertainment Center (FEC) model. They are bolting on “Sky Rider” ziplines, 30-foot climbing walls, and electric go-karts.
- Urban Air Port St. Lucie (2025): 6-year-old Emma Riddle was killed when a mechanical failure caused her go-kart to surge into a wall.
- Altitude Gastonia (2019): 12-year-old Matthew Lu fell 20 feet to concrete because an attendant failed to secure a harness. The park’s response? They admitted “human error” and permanently removed the attraction.
- Urban Air Sugar Land (2022): The Lakhani family suit alleges their 14-year-old daughter fell 30 feet from a climbing wall because the harness was never attached.
The Breach: The teenager supervising these high-stakes mechanical attractions is often a 17-year-old hired two weeks ago with 4 hours of total training. Their failure to secure a belt or monitor a court isn’t just an “oops.” It is a structural failure of management to prioritize safety over throughput.
The Corporate Architecture Designing Your Risk
If you pursue a case in City of Blue Mound, you aren’t just suing a local LLC. You are entering a battlefield occupied by private equity sponsors and multi-layered corporate towers.
- Sky Zone, Inc. (f/k/a CircusTrix LLC): Since January 1, 2023, this entity has served as the parent for Sky Zone, DEFY, and Rockin’ Jump. It is backed by Palladium Equity Partners, a firm that manages billions. When they approve cost-cutting measures that reduce the number of court monitors per jumper, they are setting the stage for your child’s injury.
- Unleashed Brands: The parent of Urban Air, acquired by Seidler Equity Partners in February 2023. At the time of the deal, headlines read: “Seidler Equity Buys Unleashed Brands AMID LAWSUITS Aimed at Kid-Focused Franchisor.”
These companies hire corporate defense firms with unlimited budgets. We don’t care. Ralph Manginello has gone head-to-head with some of the largest companies in the world, including BP after the Texas City refinery disaster. We have litigated cases against Walmart, Amazon, FedEx, and UPS. We understand the “5-Layer Defendant Stack” (Operator LLC → Franchisee → Franchisor → Parent → Private Equity). We know where the insurance money lives—umbrella policies, excess layers, and franchisor “additional insured” coverage. We follow the money until there is enough to cover your child’s lifetime of care.
Texas Law: Why Your Waiver is Noise, Not a Wall
In City of Blue Mound, the first thing a park manager or an insurance adjuster will do is show you the waiver you signed on the iPad. “You signed this,” they’ll say. “You accepted the inherent risks. You have no case.”
They are wrong for three distinct reasons under Texas law:
1. The Munoz v. II Jaz Inc. Doctrine
Since 1993, Texas law, specifically Munoz v. II Jaz Inc. decided by the Houston 14th Court of Appeals, has held that a parent cannot pre-emptively waive a minor child’s personal injury cause of action. While the waiver may bar your derivative claims as a parent, your child’s right to compensation for their own pain, suffering, and medical needs remains intact. Your child did not sign that paper. Your child did not consent to have their growth plate shattered.
2. The Dresser “Fair Notice” Rule
Under the Dresser Industries v. Page Petroleum (1993) landmark, a Texas waiver must be conspicuous and follow the express negligence doctrine. This means the language releasing the park from its own negligence must be bold, set apart, and use the word “negligence.” A tiny font click-through on a crowded City of Blue Mound Saturday afternoon often fails this test. If the waiver wasn’t conspicuous, it isn’t enforceable.
3. The Gross Negligence Carve-Out
No state, including Texas, allows a party to waive away liability for gross negligence. In Transportation Insurance Co. v. Moriel, the Texas Supreme Court defined gross negligence as a conscious indifference to an extreme degree of risk.
- If the park knew the mat was torn (as in the Cosmic Jump $11.485M verdict) and let your child jump anyway? That’s gross negligence.
- If the park’s management instructed employees not to call 911 (a pattern documented at Urban Air locations) to avoid bad press? That’s gross negligence.
- If they failed to staff a court entirely to save on labor costs during a rush? That’s gross negligence.
Waiver laws are changing—we saw it in the 2025 Cerna v. Pearland Urban Air delegation win for the defense. But our team includes an associate attorney, Lupe Peña, who used to defend these very companies. He knows exactly how these waivers are drafted and where the holes are. He knows which clauses Texas courts are tossing out this year, and he uses that insider playbook against them.
The Evidence Clock: Why the 7-Day Window Matters in Tarrant County
While you are focused on orthopedic surgeries and MRI reports, the trampoline park in City of Blue Mound is focused on risk management.
Park surveillance DVRs typically overwrite every 7 to 30 days. By the time you get your child’s cast home, the video of the attendant on his phone during the double-bounce could be gone forever. Incident reports at these parks are frequently “revised” or sanitized by managers before they reach the insurance carrier. Waiver versions are updated on kiosk databases, sometimes purging the version your family actually saw.
Our spoliation letters go out within 24 hours of retention. We demand the preservation of:
- All multi-angle surveillance footage including 24 hours of pattern-evidence before the crash.
- Time-stamped kiosk audit logs showing the exact waiver formation event.
- Daily opening inspection logs and foam-pit rotation records.
- Individual personnel files and 90-day training records for every monitor on shift.
We use forensic tools like FTK Imager and Magnet AXIOM to acquire evidence through write-blocked imaging. If the park tells us the video is “unavailable,” we retain digital forensic examiners to interrogate their hard drives. We don’t take “it’s missing” for an answer. In Georgia, a jury awarded $3.5 million to Mathew Knight after four park cameras conveniently “glitched” at the exact moment of his open tibia fracture. Jurors hate a cover-up more than they hate the original negligence.
Pediatric Injuries: The Lifetime Damages Architecture
A trampoline injury at age 9 in City of Blue Mound is a 70-year damages problem. We don’t settle for “ER bills plus a little pain and suffering.” We build a Pediatric Life-Care Plan (LCP).
- Growth Plate Vulnerability: Children’s bones fail at the cartilage. A Salter-Harris fracture may seem fine on an initial X-ray, but a limb-length discrepancy may not manifest for five years—until your daughter’s hit a growth spurt and one leg is measurably shorter than the other.
- The Rhabdo/UH Bridge: Extended jumping for 90-120 minutes in an 85-degree indoor facility can produce exertional rhabdomyolysis. The muscle cells rupture, spilling myoglobin into the blood and risking acute kidney failure. Our firm’s $10 million lawsuit against the University of Houston uses the same medical experts we deploy for trampoline rhabdo cases. We know how to track the CK level trajectory and renal function curve to prove the park’s heat-and-hydration failure caused the organ damage.
- Infection Vertical: Foam pits are bacterial reservoirs. We have seen MRSA, cellulitis, and in rare, horrific cases, necrotizing fasciitis follow a small contact abrasion in a trampoline park. These are medical emergencies that most firms ignore. We don’t.
Our forensic economists and vocational rehabilitation experts project what your child’s injuries will cost in 2045, 2060, and 2080. We account for future corrective osteotomies, lifetime orthopedic monitoring, special education needs, and the diminution of future earning capacity.

Frequently Asked Questions for City of Blue Mound Parents
“What should I do if my child got hurt at a trampoline park in Tarrant County?”
Get medical care at Cook Children’s or a Level 1 trauma center immediately. Do not accept a “medical payment” check from the park’s insurer—this “Med-Pay Trojan Horse” often includes a release that ends your case for a few thousand dollars. Take photos of the court, the padding, and any torn matting that same day if possible. Then call 1-888-ATTY-911 within 24 hours so we can freeze the surveillance video.
“Can I sue if I signed the waiver at Urban Air or Sky Zone?”
In Texas, for a minor, the answer is almost always yes. Pre-injury parental waivers of a minor’s tort rights are generally void under Munoz. Even for adults, if the park was grossly negligent—knowing about a defect or being severely understaffed—the waiver cannot protect them. We run every waiver through a five-vector attack including conspicuousness and unconscionability.
“How much money can my family get for a trampoline injury settlement?”
Verdicts and settlements are based on the severity of the injury and the degree of negligence. The Cosmic Jump Houston verdict of $11.485 million and the Damion Collins $15.6 million award are top-tier benchmarks for catastrophic cases. Even complicated pediatric fractures often anchor in the $500,000 to $2 million range when future growth-arrest issues are properly documented by an Life-Care Plan.
“Is my homeowner’s insurance going to cover a backyard trampoline injury?”
Most standard Texas homeowners’ policies (HO-3/HO-5) exclude trampoline injuries or require a specific endorsement. If your neighbor’s child was hurt at your City of Blue Mound home, you may face an attractive nuisance claim. We look at umbrella policies and manufacturer defect theories—Jumpking has had millions of units recalled for frame weld failures. Pursuing the manufacturer often provides the deeper pocket and protects the neighborly relationship.
“How long do I have to sue a trampoline park in Texas?”
The adult personal injury statute of limitations is 2 years. For minors, the clock is tolled until they turn 18, meaning they have until age 20. But do not wait. The evidence (the video, the witness, the equipment condition) is gone in weeks. The legal deadline is not the practical deadline.
“Why is my child’s urine dark brown after the park?”
This is a medical emergency called rhabdomyolysis. It means their muscles are breaking down and poison is hitting their kidneys. Go to the ER immediately and demand a CK blood test. This is often caused by extended-jumping in overheated parks without hydration. We litigate these cases specifically.
The Case Starts Today | 1-888-ATTY-911
What happened to your child at City of Blue Mound wasn’t a freak accident. It was the predictable output of a business system that puts margin before kids. The American Academy of Pediatrics has been warning about this since 1999. ASTM F2970 established the safety floor, and the park chose to operate below it. The waiver you signed? It was drafted by people who knew it wouldn’t hold up in a Texas court, but they hoped you wouldn’t find a lawyer who knew that.
Attorney911 was built for exactly this fight. We’ve gone toe-to-toe with Fortune 500 companies and won. We know the North Fort Worth parks, we know the Tarrant County courts, and we know the medicine of a Salter-Harris fracture better than the park knows its own training manual.
