RedactedNarrative: INITIAL CALL 
  On July 16, 2014, I received a phone call at home from Officer with the National Park Service (NPS). He explained to me that there was a Personal water craft (PWC) versus personal water craft accident. Officer said that a passenger on the PWC was unconscious and had severe head trauma. Officer explained to me that he saw blood coming out of the ear of the victim. I explained to Officer that I would take the accident report and would meet up with the other officer's at the Bullfrog Clinic. 
  
  RESPONSE/NARRATIVE 
  I responded to the Bullfrog Clinic and met up with Officer. I asked Officer if she knew what took place. She explained to me that a passenger of a PWC struck the driver and was being flown out of Bullfrog. I asked Officer if she knew of any alcohol or drugs was involved in the accident. She explained to me that she did not know and to ask the father in the clinic. I asked if this was a fatal or could go fatal she said that she did not know. I asked Officer where the PWC involved in the accidents were located she said that one was down at the main launch ramp and she did not know where the other PWC was at. Officer told me that the houseboat family members involved in accident were down at the covered slips specifically slip "O-2". 
  
  I left the clinic and arrived at the covered slips. At slip O-2 I contacted a male individual. I explained to the male individual who I was and asked if he was involved in a boat accident today. He said that he was and identified himself and Operator2. I asked if there were any adults around that I could talk to. Operator2 said no that everyone was up at the clinic with his brother. I asked Operator2 if he could point out the PWC involved in the accident to me. He said that he could and retrieved the registration and insurance paper work for me. I could tell Operator2 was very upset and nervous. Operator2 hands were shaking and he seemed like he was crying earlier. Operator2 continuously bit his nails and did not want to make eye contact. Due to the fact Operator2 was 15yrs old I did not ask any more questions and explained to Operator2 that I would be looking over the PWC. Operator2 went back inside the houseboat while I looked over the PWC. 
  
  Looking over the PWC I found very little damage. I looked closely at the bow of the boat and bow eye and found very little damage. I found some scratches and nicks in the plastic, but I would be informed by the owner those occurred prior to the accident. Photos were taken of the PWC. 
  
  I waited at the houseboat for the other PWC involved in the accident and family members to arrive. 
  
  A male individual arrived and docked at the back of the houseboat. I introduced myself and explained to the male individual that I would be taking an accident report. The male individual identified himself as Operator1. He said that he was driving the other PWC involved in accident. 
  
  I conducted my interview with Operator1 and his son on the bow of the houseboat. Operator2 presented me with his PWC safety certificate from Utah. I asked Operator2 what took place. He said that he was following his dad and brother on a PWC when they stopped in front of him. At the time Operator2 wasn't paying attention and hit the PWC causing his brother on the other PWC to hit his father in the back of the head with his own head. Operator2 said that his brother then fell into the water. I asked Operator2 if the PWC came up out of the water at any time. Operator2 said he did not remember the PWC coming out of the water. I asked Operator2 if the PWC struck his brother he said no. I asked Operator2 how fast he was going at the time of the accident. He replied around 10mph. I asked Operator2 if he was on the throttle at the time of the accident.
