The designer of a waterslide that killed a 10-year-old boy at the Schlitterbahn Kansas City water park in 2016 has surrendered to U.S. Marshals after returning to the country on Monday night, according to ABC News.

According to the U.S. Marshals Service, the North Texas Fugitive Task Force took John Schooley into custody at Dallas-Fort Worth International Airport after the designer returned from China.

Schooley, 72, was indicted last week on charges of second-degree murder, aggravated battery and aggravated endangering of a child.

The water park company’s co-owner Jeffrey Henry is accused of rushing the world’s tallest waterslide into service.

Henry was arrested March 27th in South Padre Island, Texas, by the U.S. Marshals Service.

Caleb Schwab was decapitated after the raft on which he was riding went airborne. He was the son of Republican state Rep. Scott Schwab, of Olathe, and 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 with Caleb suffered serious injuries and settled claims with Schlitterbahn for an undisclosed amount.

The second indictment follows a Kansas grand jury’s indictment last week of the Schlitterbahn park in Kansas City, Kansas, and a former operations director on 20 felony charges. They included a single count of involuntary manslaughter over the death of Caleb.

The charges will be prosecuted by the Kansas Attorney General’s Office, which assumed responsibility for the case in December 2016 at the request of the Wyandotte County District Attorney’s Office.
