A young girl was saved by a couple when they managed to keep her in a Kansas City roller coaster seat after its restraints failed – and the heroic action was captured on camera.
Chris and Cassie Evins were riding the Mamba at Worlds of Fun on October 11 when they heard ‘blood-curdling’ screams coming from the seat behind them. They said a girl’s seatbelt had come undone during the ride’s first hill.
Chris told KCTV5 the scream was ‘like I’ve never heard before,’ and that he ‘assumed it was her first time on the ride.’
But when the girl said her seatbelt had come undone, the couple leapt into action and reached over to keep her inside.
Chris said: ‘I had looped my arm underneath her lap bar, which had a pretty big gap between her and the lap bar. So at this point, I’m seeing a huge space, no seatbelt.
‘I looped my arm underneath the lap bar, and I grabbed a hold of her wrist. My wife was pushing down on her legs.’
The couple have season tickets to Worlds of Fun, so they are familiar with the Mamba, which stands at a daunting 208 feet at its highest point and reaches speeds up to 75 miles per hour, according to the park’s website.
As the couple held on to the panicked girl, they knew the rollercoaster had upcoming hills and turns which could launch her out of the unsecured seat.

Chris said that in anticipation, he ‘shifted our positions to, instead of hold her, to push down on her whole body to keep her from coming out of the seat while we’re going over those hills.’
The Evinses’ quick thinking likely saved the girl, as they were able to keep her secured until the ride ended.
The roller coaster camera which usually captures riders’ screams of amusement documented the much more serious and terrified screams of the Evinses and the girl they were helping.
In the photo, Chris and Cassie can be seen reaching into the seat behind them with distraught looks, and the girl can be seen bent forward with a petrified expression on her scrunched face.
The couple immediately reported the horrifying experience to the park, who assured them the ride was closed for inspection for the remainder of the day.
A Worlds of Fun spokesperson told the Daily Mail: ‘The safety of our guests and team members is a top priority. Following the report of a guest concern on the ride several weeks ago, our team immediately closed the ride and completed a thorough inspection before reopening it that evening.
‘The ride is equipped with a multi-layered restraint system, with lap bars being the primary restraint. The seat belts serve as a secondary restraint.
‘Throughout multiple inspections, there was no evidence of restraint failure in the lap bar system or the buckles on any seat belts during any of the ride inspections and the ride has operated safely since the initial concern was raised.’

Chris said that after the terrifying ride was over, he thought: ‘What if it had been somebody else in our seats? What if it was others, her friends? You know, they could have had a drastically different outcome.’
The Evinses said that they were separated from the girl and were not able to speak with her after helping. They also said they are trying to connect with the family.
The Mamba’s last inspection prior to the terrifying close call was on April 25, 2025. A series of inspections since the girl’s seat belt failure took place on the same day and following days.
Mike O’Connell, a spokesman for the Department of Public Safety, told the Kansas City Star that one of those inspections on October 30 determined that several belts on the ride were found to be not working properly.
The park spokesperson said: ‘On Thursday, the ride underwent a comprehensive safety review by the Fire Marshall.
‘Again, the lap bars and buckles were found fully functional, and we implemented slight modifications to a number of seat belts to ensure they met or exceeded all applicable safety standards before the ride opened to guests that evening.’
