RedactedNarrative: Operator1 said that they were pulling into the slip after being out on the lake all day. Operator1 said that Victim was on the swim platform and told her not to back up because he was going in (water). Operator1 replied to Victim that she could not back up because she had the engine turned off. Both subjects heard the splash of water behind the boat. Victim surfaced after jumping into the water and yelled "Hey operator". Operator1 turned towards Victim and saw him flick his head back like he was trying to get his hair out from his face. At that moment Victim went under the surface of the water and was not seen again. Subject2 and Operator1 thought Victim was playing a trick and didn't think anything of it, until he did not surface several seconds later. Panic set in and both Subject2 and Operator1 began to yell for Victim. Two people walking by heard the yelling and joined in looking for. They were unable to find Victim and 911 was then dialed by Subject2. Operator1 then jumped onto the Rinker docked in slip six (6) and was trying to feel under the water. It was then she was shocked on her arm. 
   
  I asked Operator1 where in the water was his last known location she pointed out from the dock about ten feet to fifteen feet (10ft to 15ft) from the end of the finger of the dock between slip 6 and 7. I asked operator how much alcohol Victim consumed. She pointed out that all of his beer was Coors Light and Budweiser cans and no one drank anyone else's beer. It was determined that Victim drank in total twenty (20) beers over the course of the trip on the water. Due to the fact I was congested and unable to smell several other officers explained to me that they could smell the odor of alcohol coming from Operator1 and Subject2. I asked Officer to use a PBT to determine the presence of alcohol. Officer informed me later that Operator1 was a 0.083 and Subject2 was 0.000. operator1 was very hysterical during my interview and I decided not to question her any more on what took place. I explained to operator1 and Subject2 that they could retrieve any personal belongings from the boat and to secure the boat for the night. I explained to Operator1 and Subject2 not to discuss the incident with anyone else due to the fact that the parents of Victim were not notified and we did not want them to find out through social media. Officer escorted Operator1 and Subject2 up to the lodge for the night.
   
  In talking with the NPS divers they found Victim lying face up on the lake bottom. He was positioned was on a slight slop with his head lower than his feet. The depth they found Victim was at 117ft to 123ft. 
  
  While we were investigating the power problem the owners of the boat docked in slip six (6) arrived on scene. I began to question Boat operator2 about his boat and why it was parked in slip six (6). Boat operator2 explained to me that he and his wife were looking for a place to dock their boat for the night. Boat operator2 said that all the other slips on "G" dock were full and that he docked there to find Aramark staff to ask if that was okay. Boat operator2 said that he was unable to locate any staff so he and his wife along with their eighteen (18mo) month old went to eat dinner at the lodge. I asked Boat operator2 who was on the boat at the time he dock he said no one. His wife was on shore driving their truck over to the covered slip dock. I explained to Boat operator2 that while he was away a male individual was missing in the water directly behind his boat. I was able to identify the boat docked in slip six (6) as a 2000 Rinker Fiesta Vee owned by Boat operator2 and his wife. I asked Boat operator2 what time he docked his boat. Boat operator2 replied around 18:00MST. I asked what was turned on in the boat. Boat operator2 said just the AC unit because he had dogs in the cabin. I questioned Boat operator2 about any work that was done on the boat. Boat operator2 said that over the winter he had work done on the generator by a boat deal
