I found this reading Coasterbuzz. I believe this is from someone in Public Relations at Holiday World.
"It is with great sorrow that we inform you there was a fatality at Holiday World on Saturday, May 31. A female guest visiting from the East Coast was involved in an accident at The Raven roller coaster shortly before the park closed to the public for the evening. She was not in her seat when the train returned to the station. A doctor who was a guest at the park, plus the parks’ EMTs were on the scene within minutes and performed CPR and other emergency procedures until an ambulance arrived. The woman, whose name has not been released, was transported to the local hospital, where the coroner pronounced her dead. The Koch family and everyone at Holiday World & Splashin' Safari are devastated by this tragedy. Our prayers go out to the family. The park family will be in mourning on Sunday, June 1, and Holiday World & Splashin' Safari will be closed to the public on that day. A private counseling session will be available to all employees at the park at 1:00 pm Sunday. An investigation is underway. This message will be updated as more information becomes available. Sincerely,The Koch Family "
