RedactedNarrative: SYNOPSIS
  Responded to and investigated an injury vessel accident that occurred in Kane Wash on 7/4/19 at approximately 1830 hours. One injured party received a large laceration to back and arm and was flown to Dixie Regional Hospital. During the course of the investigation it was determined that the vessel involved struck a submerged island and ejected two passengers, and ran over one of those passengers (injured party). Witnesses nearby responded and rendered medical treatment and transported the injured person to the Antelope Launch Ramp. The operator of the vessel was arrested for driving under the influence and causing serious bodily injury, reckless driving, and failure to keep a proper lookout.
  
  I spoke with a female, and she informed me she had been on the vessel when the accident occurred.  She told me they had gone to the marina from their camp to fuel their ski boat and were returning to their camp in Kane Wash.  She said they were almost back to their camp when they hit a "sand bar" and injured the male, Victim, had been ejected and she thought the boat had run him over.  She informed me they were staying on Aramark Rental Houseboat.  I asked Subject1 what time she thought the accident had occurred and she just checked her phone to see what time they had attempted a 911 call and it showed about 1845 hours.  She stated that was after approximately 10-15 minutes of initial care and the start of the transport of Victim, which would make the time of the accident approximately 1830 hours.  I asked Subject1 to fill out a witness statement.  I also spoke with subject2 (very upset) and subject3 (very obviously intoxicated) and they stated they were also on the vessel when the accident occurred.  Subject2 stated Victim was her boyfriend.  I asked them both to fill out witness statements.
  While at the ramp I had heard Ranger was conducting field sobriety tests with Operator and then later had placed him under arrest.  I contacted them and asked them to wait at the camp for my arrival, which they agreed to do.  
  While we were tied to the stern of the rental houseboat some nearby neighbors came over on a PWC and gave us a large bronze fin and a blade off a propeller they stated they had just found on the island that was struck.  I took them and thanked them for bringing them over.  They appeared to match the type of fin and propeller that would be on the vessel involved in the accident.
  
  At approximately 2050 hours I took custody of OPERATOR and informed him of who I was.  Ranger informed me that he had been observing OPERATOR from 2018 hours for the intoxilyzer test.  I asked OPERATOR when he had last drank alcohol and he just looked at me.  I asked if his last drink of alcohol was prior to the accident and he stated it had been.  At 2051 hours I informed OPERATOR that he was under arrest for DUI and read the admonition requesting he submit to a breath test.  See DUI citation report for more information.  
  At approximately 2130 hours I issued OPERATOR a citation for DUI causing serious bodily injury, reckless driving and failure to keep a proper lookout.  I released him to a third party in their group whom had confirmed she was over 21 yrs of age and was not intoxicated (0.000 on PBT). I informed OPERATOR and the rest of the group who wasn't coming back to the marina with me that I wanted them to stay in this location on the houseboat until I returned the following morning to finish my investigation into the accident.
