This is reportedly not the first fatal accident to have taken place in connection with the Raging River ride at Adventureland Park.

According to the Des Moines Register, 68-year-old Adventureland Park employee Steve Booher died in 2016 while working on the ride. He was helping riders get out of the rafts at the end of the ride and fell onto the conveyor belt, suffering a fractured skull along with a major brain injury, the paper reported. Booher died four days later.

An investigation into Saturday's incident is ongoing and the ride will remain closed during that time.
