DALLAS — The designer of the water slide that decapitated a 10-year-old boy at Schlitterbahn's Kansas City park in 2016 was arrested Monday evening at DFW Airport.

John Schooley, 72, who designed the 17-story Verruckt water slide, is accused of negligent planning that resulted in the death of Caleb Schwab. 

He was arrested after returning to the U.S. from China and will be will be held in North Texas until his arraignment in Kansas, the Kansas City Star reports. 

According to the Star, he is being held without bond and is expected to be taken to Kansas for a first appearance before a Wyandotte County judge.

Schooley from New Braunfels, Texas, has been charged with second-degree murder in the death of Schwab, who died riding Verruckt in Kansas City, Kan., in 2016.

Park owner Jeffrey Wayne Henry, 62, was arrested in South Texas on Monday, March 26, on charges stemming from the investigation into the boy's death.

Records show that Henry, co-owner of Schlitterbahn Waterparks and Resorts, was booked into the jail in Cameron County, Texas. He was being held without bond, and a jail booking clerk said he would remain there until a court appearance Tuesday.

Henry's arrest Monday follows a Kansas grand jury's indictment last week of the Schlitterbahn park in Kansas City, Kansas, and its former operations director, Tyler Austin Miles, on 20 felony charges. They included a single count of involuntary manslaughter over the death of Caleb Schwab in 2016.
