RedactedNarrative: On july 15, 2018 at 2001, officer informed me that there had been a personal injury boat incident on the cedar river at waverly. Officer told me that a boat pulling tubes had run over the top of several people that were floating down the river on innertubes. Officer informed me that a female on one of the innertubes had suffered injuries to her head. I also learned that the driver of the boat had remained on scene, and that he had admitted to officers that he had been drinking prior to the collision.  Officer informed me that the boat operator had failed field sobriety and had consented to a field test on a pbt. The results of the pbt showed a blood alcohol concentration that was well above the legal limit of .08.
  
  The victim had received a deep laceration to the back of her head, but medical staff didn't believe that she had suffered any traumatic brain injuries. I then requested permission from the nurse at the desk to go into the er room and speak with victim. Having received permission, i entered the hospital room and saw a female lying on the bed. The victim appeared to be conscious, but was wearing a c-spine neck brace which made it impossible for her to move her head. I then introduced myself and asked if i could ask a couple of questions in regards to the incident. Two other people were in the room with victim, and i they informed me that they were her mother and father. I asked victim if she could tell me what had happened, and she said that she couldn't remember anything. The father did tell me that she had been with her fiancé and several other friends on a float trip down the river for her birthday. 
  
  The group had floated down river to a sandbar, and had briefly stopped for a bathroom break. The group then got back on their inner tubes and started floating downstream again. It was shortly after they departed from the sandbar when the collision occurred. The tubers were headed downstream, and the power boat was headed on plane against the current upstream pulling a large inflatable ski-toy. 
  
  Subject2 described the boat as being at an approximate 15degree angle, moving at what he thought was 20-25 miles per hour. I had asked if the boat was nose-up and "plowing water", and he replied no. The tubers said that they could clearly see the driver looking back at and motioning towards the two people he was towing. I learned that operator was in the powered vessel by himself, and that he did not have a "spotter" on board as required by law. The tubers said that several of them saw the boat coming directly at them, and that they had screamed and attempted to get the attention of the boat operator. The powerboat operated by operator then plowed directly into the flotilla of tubers. Victim was facing upstream in her tube at the time of collision. She took the brunt of the impact, with the powerboat hitting her squarely. After impact, the boat continued upstream a short distance before operator Stopped and attempted to stop to render aid. The tubers that had been struck were picked up by a third-party vessel that wasn't associated with operator or the tubing group. The tubers were transported to the lower parking lot of the waverly area veterans club. At this point victim was transported to the waverly hospital er via ambulance.
  
  Two people did not want medical attention at that time despite having obvious injuries and talking about pain. Subject1 had a large red mark under his right eye, and a red abrasion to the back-right side of his neck that caused him great pain when touched. Subject3 complained of pain to his legs
  
  Victim had a very large cut to the back-left of her head. The er had used staples to close the wound. Victim also showed a red mark on the front-left side of her head. I then left the er room. Victim was released from the hospital a short time later.
  
  We inspected the vessel and took numerous photos of it inside and out. There were no obvious signs of blood or impact on the vessel around the propeller. There was a bent tracking fin on the bottom of the vessel (c.e. Operator contacted officer later to report that the fin had been bent prior to him purchasing it. 
  
  Operator analysis showed a blood alcohol concentration of .125. None of the  victims had life jackets. Only 1 received medical attn.
