The Latest on the investigation into the death of a boy killed while riding the world's tallest waterslide at a water park in Kansas City, Kansas (all times local):

11:35 a.m.

A spokesman for police in Kansas City, Kansas, says the death of a boy killed while riding a waterslide at a local water park is considered a criminal investigation because a death was involved.

Officer Cameron Morgan confirmed Monday that police were investigating the death of 10-year-old Caleb Schwab. He said investigators didn't believe anything criminal happened, so it would be a "civil matter."

On Tuesday, he clarified that the investigation is a criminal case because a death was involved, as is standard procedure. He reaffirmed that police don't believe any criminal wrongdoing occurred and are investigating to rule out that any crime was committed.

Caleb was one of three passengers riding in a raft on the Verruckt waterslide at Schlitterbahn Waterpark when the accident occurred. Emergency responders found the boy dead in a pool at the end of the ride. The other passengers sustained minor facial injuries.
