A thrill ride billed as the world’s tallest waterslide remained off-limits Monday as authorities pressed to figure out how a state lawmaker’s 10-year-old son was killed on a day the park honored elected officials and their families.

Details remained murky about how Caleb Thomas Schwab died Sunday on the 168-foot-tall “Verruckt” – German for “insane” – that since its debut two years ago has been the top draw at Schlitterbahn Waterpark in Kansas City, Mo.

In a statement Monday afternoon, Schlitterbahn said it was “deeply and intensely saddened for the Schwab family and all who were impacted by the tragic accident.” The park was tentatively scheduled to reopen Wednesday, but “Verruckt is closed,” according to the statement.

Officer Cameron Morgan, a police spokesman, said no police report about the incident was available. He said investigators were treating Caleb’s death as a “civil matter” rather than a criminal one and referred additional questions to the park.

Schlitterbahn spokeswoman Winter Prosapio declined interview requests Monday but told reporters a day earlier that Caleb had been at the park with family members, adding that “we honestly don’t know what’s happened.”
