TOPEKA, Kan. — A water park co-owner accused of rushing the world’s tallest waterslide into service and a designer accused of shoddy planning were charged Tuesday in the decapitation of a 10-year-old boy on the ride in 2016.

With the latest charges, three men connected with Texas-based Schlitterbahn Waterparks and Resorts and its park in Kansas City, Kansas, have been indicted by a Kansas grand jury, along with the park and the construction company that built the ride. Caleb Schwab died on the 17-story ride when the raft he was riding went airborne and hit an overhead loop.

The Kansas attorney general’s office said Schlitterbahn co-owner Jeffrey Henry, 62, and designer John Schooley were charged with reckless second-degree murder, along with Henry & Sons Construction Co., which is described as the private construction company of Schlitterbahn.

They also were charged with 17 other felonies, including aggravated battery and aggravated endangerment of a child.
