The designer of Schlitterbahn's "Verruckt" water slide was taken into custody at Dallas/Fort Worth International Airport Monday night.
The water park company's co-owner Jeffrey Henry is accused of rushing the world's tallest waterslide into service and the designer, John Schooley is accused of shoddy planning.
Both were recently charged with reckless second-degree murder in the decapitation of a 10-year-old boy on the ride in 2016. Caleb Schwab died on the 17-story ride when the raft he was riding went airborne and hit an overhead loop.
Henry & Sons Construction Co., which is described as the private construction company of Schlitterbahn, was also charged with reckless second-degree murder. Second-degree murder carries a sentence of 9 years to 41 years in prison.
The latest news from around North Texas.
They also were charged with 17 other felonies, including aggravated battery and aggravated endangerment of a child counts tied to injuries other riders sustained on the giant slide, called Verruckt, which is German for "insane." The indictment accuses Henry of making a "spur of the moment" decision to build the ride, and that he and Schooley lacked technical or engineering expertise in amusement park rides.
Henry was ordered held in a Texas jail without bond last week, pending extradition to Kansas.
The attorney general's office said Monday night that Schooley was taken into custody at DFW International Airport after arriving on a flight from China.
Schooley will be held in North Texas until an arraignment to Kansas.
The same grand jury last week indicted the Kansas City park and Tyler Austin Miles, its former operations manager, on 20 felony charges. The charges include a single count of involuntary manslaughter in Schwab's death. Miles has been released on $50,000 bond, according to one of his attorneys, Tricia Bath.
The company has promised to aggressively fight the criminal charges. After Miles and the park were charged, it said it would respond to the allegations in the 47-page indictment "point by point."
After Henry's arrest in Texas, Schlitterbahn spokeswoman Winter Prosapio said in an emailed statement: "We as a company and as a family will fight these allegations and have confidence that once the facts are presented it will be clear that what happened on the ride was an unforeseeable accident."
According to the indictments, Henry decided in 2012 to build the world's tallest water slide to impress the producers of a Travel Channel show. Henry's desire to "rush the project" and a lack of expertise caused the company to "skip fundamental steps in the design process."
The indictment said, "not a single engineer was directly involved in Verruckt's dynamic engineering or slide path design." The indictment said that in 2014, when there were news reports emerging about airborne rafts, a company spokesperson "discredited" them and Henry and his designer began "secretly testing at night to avoid scrutiny."
The indictment listed 13 injuries during the 182 days the ride was in operation, including two concussions. In one of those cases, a 15-year-old girl went temporarily blind while riding.
Caleb, the son of Kansas Republican state Rep. Scott Schwab, was decapitated after the raft on which he was riding went airborne on a day when admission was free for state legislators and their families.
The family reached settlements of nearly $20 million with Schlitterbahn and various companies associated with the design and construction of the waterslide. The two women who rode on the same raft with Caleb suffered serious injuries and settled claims with Schlitterbahn for an undisclosed amount.
"Clearly the issues with Schlitterbahn go far beyond Caleb's incident, and we know the attorney general will take appropriate steps in the interest of public safety," the family said in a statement released Monday through their attorneys.
The indictment said Schooley was responsible for doing "the math" that went into the slide's design and signed an operations manual claiming the ride met all American Society for Testing and Materials standards. But the indictment lists a dozen instances in which the design violated those standards and says investigators could find no evidence that so-called dynamic engineering calculations were made to determine the physics a passenger would experience. The indictment said Schooley lacked the technical expertise to properly design a complex amusement ride such as Verruckt.
The indictment said Schooley admitted, "If we actually knew how to do this, and it could be done that easily, it wouldn't be that spectacular."
Prosapio said Schlitterbahn does not expect any changes to the Kansas City park's season, which is set to open May 25 and runs through Labor Day. The Verruckt slide has been closed since Caleb died.
Mike Taylor, a spokesman for the Unified Government of Wyandotte County and Kansas City, Kansas, says it does not believe it has the legal authority to shut down a business, other than for an epidemic or contagious disease outbreak.
The company also operates water parks in Galveston, Corpus Christi, South Padre Island and New Braunfels, Texas, according to its website.
