The world’s tallest water slide turned deadly on Sunday after a Kansas state lawmaker's son was killed on the attraction. Caleb Thomas Schwab, the son of Rep. Scott Schwab, died on the 17-story water slide known as the Verrückt, which Kansas City's Schlitterbahn Water Park promotes as being taller than Niagara Falls. The slide sends up to three riders on a raft speeding 60-70 mph down a height of 168 feet and seven inches. Officers are still investigating the scene, calling it an “apparent accident death,” Kansas City police chief Terry Zeigler said.
