RedactedNarrative: On August 30, 2015 at approximately 1130 hrs, Operator was operating a jet ski, borrowed from his friend.  Operator stated he was approximately 15 feet outside of the "no boat zone" at Anderson Beach and Swim area riding the jet ski in circles and in straight lines. Operator stated he was probably going no more than 10 miles per hour on the jet ski.  Operator stated he had seen some swimmers close to the buoys that prohibit vessels from entering the swim area at Anderson Beach. Operator stated that he lost sight of one of the swimmers as she went under water and when she resurfaced, she was right in front of him. 
  
  Subject stated he turned left to avoid hitting the swimmer and that the starboard, stern area of the vessel struck the swimmer in the head.  Operator stated he was probably going 5mph when he struck her. After he realized what had happened, Operator stated he jumped off the vessel and assisted the swimmer back to shore.
  
  The victim/swimmer stated she was swimming inside the buoys approximately 6 feet towards the swim area with a friend when she heard a noise.  She stated that she was not aware of a jet ski in the area and the next thing she knew was that she felt something hit her head and the jetski go by her. She stated the jetski was going fast but quickly returned to help.
  
  Victim was transported via ambulance to Summit Medical Center. She was complaining of pain behind her right ear and right shoulder area.  There was no apparent injury to the outer appearance of her body; however, she did say she felt some swelling on her head. Victim was treated and released from the hospital on the same day.
  
  A witness stated that he saw both the swimmer and the jet ski operator close to the buoys. He stated he could not tell 100% if the jet ski was inside the buoys or if the swimmers were outside the buoys.  Witness1 stated he heard the aftermath and saw people running and swimming to help so he started sprinting to help, as he is an experienced swimmer. Witness1 stated to me over the phone that he did not think the situation was as bad as people around the area were making it out to be.
  
  Another witness who was swimming with Victim, stated that she had seen the jet ski and the next thing she knew was that victim was yelling for help and she saw the jetski "flew past towards the swim area". She then yelled for him to come back and help.
  
  Another witness stated to me that when the accident happened, she thought that Operator was inside the buoys where no vessels are allowed to be.  Witness3 was at a work picnic and one of the employees was taking pictures of the event that day.  Witness3 was looking at the pictures and noticed that the employee had somewhat captured the incident on the camera.  Witness3 sent me the pictures and as she states, they were taken just seconds before the impact. The photos show the jet ski approximately 20 feet on the outside of the buoys, away from the swim area. At the time of impact, there was a picture taken; however, there is a tree in the way but you can see Witness3 with her hand over her mouth and her friend holding her arm, in shock of the accident. She stated that this picture is when the accident occurred. The picture still appears to show the wake of the jet ski outside of the buoys.
  
  There were no apparent signs of intoxication by Operator and he stated that he had not had any alcoholic beverages and that he had not taken any drugs that day. I asked Operator to consent to taking a blood test and he did consent.  I took Operator to have a blood sample taken at Summit Medical Center and then returned him to his friends at Anderson Beach.
