The parents of a 10-year-old girl who died of cardiac arrest after getting too excited on a water slide are heartbroken. London Eisenbeis was so thrilled to finally ride a Michigan amusement park’s water slide in February 2018 that she suffered a fatal heart attack, her parents said. “The last time I saw London, she was smiling at the top of that ride. She gave me a thumbs-up,” her father, Jerry, told Inside Edition. London had waited for two years until she was tall enough to go on the slide.
