A 10-year-old boy was decapitated as he rode a 168-foot tall waterslide at a water park in Kansas, a person familiar with the investigation said Wednesday.

The person spoke on condition of anonymity because the person is not authorized to speak about Caleb Schwabโ€™s death Sunday on the raft ride at the Schlitterbahn WaterPark in Kansas City, Kan.

Two women who are not family members were in the raft at the time with the boy and were treated for facial injuries. The boyโ€™s parents โ€“ Republican state Rep. Scott Schwab and his wife, Michele โ€“ have requested privacy and have not spoken publicly since the death. His funeral is scheduled for Friday.

A spokeswoman for the waterpark on Wednesday declined to discuss the circumstances of the boyโ€™s death. The Guinness World Records has certified the ride called โ€œVerrucktโ€ โ€“ German for โ€œinsaneโ€ โ€“ as the tallest in the world.

The park reopened Wednesday except for the sprawling section including the waterslide, although its towering profile greeting visitors as soon as they drove through the entrance.

Verruckt riders sit in multi-person rafts that begin with a steep drop, followed by a surge up a second hill before a 50-foot descent to a finishing pool. Each Verruckt rider must be at least 54 inches tall, and the combined body weight of the riders on each raft is limited to 400 to 550 pounds.

Riders are harnessed in with two nylon seatbelt-like straps โ€“ one that crosses the riderโ€™s lap, the other stretching diagonally like a car shoulder seatbelt. Each strap is held in place by long Velcro-style straps, not by buckles. Riders also hang on to ropes inside the raft.

Pulling a cooler behind her, 42-year-old Sara Craig said she was looking forward to an afternoon of water fun Wednesday with her 14-year-old son, Cale, and one of his 13-year-old friends.

But she said the visit came with a twinge of unease, given Sundayโ€™s tragedy.

โ€œI feel guilty having fun when a family is hurting so badly,โ€ she said.

She said the family rode Verruckt twice in one day a couple of weeks ago. She remembered a short video they were required to watch, though she didnโ€™t recall that it including any caveats about peril.

Craig said that during her first trip down the ride with her son and one of his friends, her shoulder restraint came off, something she opted not to report to park workers.

โ€œI didnโ€™t think much about it,โ€ she said. โ€œYou donโ€™t think youโ€™re gonna die.โ€

So they rode it again, only to see the restraint on her sonโ€™s friend also come loose by the time it was over.

She said the rideโ€™s operators sent them down the slide even though their combined weight was 393 pounds โ€“ shy of the weight limits the park advertises as a requirement. Craig described the ride as โ€œvery, very rough,โ€ so much so that โ€œwhen I got off, my head hurt.โ€

The water park passed a private inspection in June that included Verruckt, according to a document released by a Kansas state agency.
