RedactedNarrative: On 9/16/2017 at approximately 8:20 pm V1 was involved in a single vessel crash. Park Officer stated that a male subject was operating the boat when it came into the Rock Creek Marina and campground near Camanche Iowa in the County of Clinton.  Upon initially investigation there was conflicting stories as to who was operating the boat at the time of the incident, occupant or Operator. The officers on scene stated there were seven occupants on the vessel, one had a severe laceration to the head and was being transported to Genesis East in Davenport. Another female occupant had a hand injury and her ring had to be cut off. 
  Conservation Officer was still in route at the initial report of the incident and advised the Deputies on scene to get statements from everyone, determine who was the operator, do PBT's and FST's on both potential operators if they were not cooperating.  Upon arrival, Officer was notified that the male subject, had opened a beer and began drinking it before the deputy noticed it and ordered him to stop.  Operator stated he wanted to go to the restroom, which they were standing near, and never returned to the area.
  Park Officer was informed that he went near a campsite however was unable to locate him.  Occupant was able to reach her husband on the phone and he stated he was walking toward Grand Mound, Iowa. Both Park Range and Conservation Officer informed Operator to return immediately to the scene but Operator refused.  Operator was not located the rest of the evening. Occupant stated that her husband had been drinking and that he acts like that and is difficult when he is drunk.  Occupant stated that they had been in the "Party Pit" since about 2:00 pm and that they left the party pit after dark and that she was driving back to the marina and as they were cutting through the cut between 2 islands they didn't immediately see 2 boats in the cut and veered to the right.  
  That is when they hit something and then a female teenager on board started screaming she had been cut.  Occupant stated that she then told Operator to drive the boat and she, as a nurse began attending to the victim. As Officer was talking to Occupant, he noticed her eyes were bloodshot and watery and there was an odor of alcohol coming from her facial area.  Officer asked if she had been drinking and she stated 4 Mikes Hard Lemonade's starting at approximately 2 pm.  A PBT was administered with a result of 0.050 BAC.  All individuals on the boat kept stating "they didn't know who was driving the boat" 
  Officer spoke with 4 subjects who were fishing in the fishing boats in the cut where the incident occurred.  The subjects stated they were anchored in the cut fishing with their navigational lights on. They stated that a vessel traveling at a high rate of speed came into the cut and swerved to the north of them striking a tree in the water.  
  They stated the vessel did not slow down and kept on going down river and another smaller vessel followed.  The four subjects then noticed that the ski tower from V1 was hanging in the tree that was struck.  They all stated that it was too dark to see who was operating the vessel.   Officer took over the investigation in the morning of September 17, 2017.  He continued to interview all occupants, witnesses and operators.
