“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 the voice of Kati Hill, a mother who watched her three-year-old son Colton suffer a broken femur at a trampoline park. She, like so many parents in City of Krum, believed the facility was a controlled, safe environment for a Saturday afternoon. She ended her public warning with five words that haunt every family we represent: “We had no idea.”

At Attorney911, we know that what happened to your child in City of Krum wasn’t a “freak accident.” It was the predictable output of a system designed to maximize ticket sales while minimizing safety expenses.

They have an army of lawyers; so do you.

While the Texas statute of limitations provides a window to file, the park’s surveillance DVR may overwrite the footage of your child’s injury in as little as 7 to 30 days. We are built for this fight. Our spoliation letters go out within 24 hours of your retention, and we
