RedactedNarrative: INITIAL REPORT:
  On September 18, 2016 at approx. 1055 MST Range, received a report from park dispatch of a medical trauma at the Wahweap Boat Rentals. Upon Arrival all involved Rangers rendered medical care to an adult Asian male had sustained severe lacerations to his left buttocks as well as a compound fracture to his left tibia. Both injuries were consistent with having been struck by a vessel propeller. VICTIM was airlifted via helicopter to Flagstaff, AZ.
  
  INVESTIGATION: 
  I conducted a field interview with the only English speaking individual who was present at the time of the accident. SUBJECT stated that there were four individuals on the vessel. SUBJECT stated that while approaching Castle Rock Cut no wake zone OPERATOR1 made a sharp turn while they were moving at on plain speed. VICTIM who was sitting on the bow of the vessel fell overboard and was subsequently struck by the vessel. They retrieved VICTIM from the water and proceeded back to Wahweap Boat Rentals. Operator stated, through translation, that he had no previous vessel operating experience.
  
  DISPOSITION:
  I have determined through VICTIM's injuries, field interviews, and observing the vessel first hand, that the cause of the accident was VICTIM riding in an unsafe manner on the bow of the vessel while the vessel was being operated by an inexperienced operator, OPERATOR1. VICTIM's injuries were consistent with the statement given by SUBJECT. All evidence suggests that VICTIM was struck by the propeller of the vessel.
  
  Time spent on report: approx. 2 hours total on scene, approximately 1 hour spent on report.
