Waterslide complaints surface after Kansas boy dies on ride

KANSAS CITY, Mo. — At least two people who rode in the last year on the same Kansas waterslide where a 10-year-old boy was killed say nylon shoulder straps came loose during the raft ride featuring a 17-story drop.

It's unclear whether the straps on "Verruckt" — German for "insane" — played any role in Sunday's death of Caleb Schwab, a Kansas lawmaker's son. Police and Schlitterbahn Waterpark have yet to explain how Caleb sustained a fatal neck injury on the 168-foot-tall ride, which the park said Tuesday would be closed for the remainder of the season.

On the 2-year-old waterslide certified by Guinness World Records as the world's tallest, riders sit in multi-person rafts that begin with the steep drop, followed by a surge up a second hill before a 50-foot descent to a finishing pool. Along the way, riders clutch ropes along the inside of the raft.

Riders are harnessed in with two nylon seatbelt-like straps — one that crosses the rider'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.

Ken Martin, a Richmond, Virginia-based amusement park safety consultant, questioned whether the straps were appropriate for what he called "nothing more than a roller coaster with water."

In early tests, rafts carrying sandbags flew off the slide, prompting engineers to tear down half of the ride and reconfigure some angles. A promotional video about building the slide includes footage of two men riding a raft down a half-size test model and going slightly airborne as it crests the top of the first big hill.

"I think they designed this ride, and they figured since stuff was flying out, we better do something to keep people from flying out," he said. "I think we have a serious issue with the restraint system. Period."

Jon Rust, a professor of textile engineering at North Carolina State University, said the material used on the straps, commonly called hook and loop, isn't designed to keep a person in the seat. It also can get old and degrade with use.

"It's got to be used in a safe manner, and that doesn't include stopping someone's fall or preventing someone's ejection," Rust said.

Paul Oberhauser told local television station KCTV his shoulder restraint "busted loose" on his Verruckt raft July 26. The Nebraska man said he "just held on," and a video shot by his wife shows the strap loose at the ride's end. Oberhauser said he reported the matter to park workers.

Kenneth Conrad told WDAF-TV that during his trip down the waterslide last year with a friend, the friend's shoulder strap came "completely off." Conrad's wife snapped a photo at the end of the ride showing the strap missing, and Conrad didn't file a complaint with the park.

The park's spokeswoman didn't return messages Tuesday from The Associated Press seeking comment on the claims. In a statement, she said "a limited portion" of the park will reopen at midday Wednesday.

Police were investigating the death as a criminal case although police spokesman Cameron Morgan said Tuesday that designation did not mean they suspect foul play.

Caleb's parents — Republican state Rep. Scott Schwab and his wife, Michele — have requested privacy and have not spoken publicly since the death of Caleb, whose funeral is Friday.

Verruckt's 2014 opening repeatedly was delayed, though the operators didn't explain why. Two media sneak preview days in 2014 were canceled because of problems with a conveyor system that hauls 100-pound rafts to the top of the slide.

Kansas statutes governing amusement rides don't specifically mention waterslides. State law leaves it to the Kansas Department of Labor to adopt rules and regulations relating to certification and inspection of rides, adding that a permanent amusement ride must be scrutinized at least once a year by "a qualified inspector."

Regulations require only that owners of permanent amusement rides retain records for a year and rides are randomly selected quarterly for a records audit.

There were no indications of further records audits, and department officials did not immediately answer questions about why that was so.

The state requested documentation from Schlitterbahn "to ensure all safety requirements have been followed." Department officials didn't immediately provide additional details.
