RedactedNarrative: On 08-19-2018 at approximately 11:30 am, the Chippewa County Sheriff's Department was dispatched to the Rod and Gun Club Boat Landing on Lake Wissota regarding a pontoon boat that appeared to have drifted into the shoreline south of the boat landing.  A witness reported the boat on the shoreline and that it was unattended but that a dog was on board. The witness told the sheriff's department that she observed a male/black and a male/white the previous day on that boat with the dog.  
  
  The subsequent investigation resulted in the Operator being found deceased on 08/19/2018 on Lake Wissota south of the pontoon boat along the buoy line east of the dam (see attached diagram).  Victim 1’s body was attached to a rope which was connected to a tube. Victim 1’s body was submerged and suspended below the tube.  The Passenger remained missing at that time.  
  
  On 08/20/2018, Wisconsin DNR Wardens, the Chippewa County Sheriff's Department, and volunteers from Bruce's Legacy continued to search for the Passenger.  The Passenger was not found until 08/21/2018 at approximately 9:00am when he was observed floating on the surface of Lake Wissota.  Investigators with the sheriff's department observed Victim 2’s body floating with the aid of their drone.
  
  The investigation showed that the Operator and Passenger went out on Lake Wissota on 08/18/2018 from the boat landing the Rod and Gun Club sometime prior to 3pm.  The Operator and Passenger sent a picture message to the Operator’s girlfriend between 3 and 4 pm while on the lake.
  
  A witness stated the she observed the pontoon boat on Lake Wissota on 08/18/18 between 4:45pm and 5:00pm. Witness stated the boat was unoccupied at that time and she also observed a tube floating near the boat that appeared to be floating in a vertical position.
  
  A second witness stated that she was looking out from her residence at the lake around 3pm (08/18/18) and observed what appeared to be an unoccupied pontoon boat moving in a southerly direction and it appeared there was a dog on board. 
  
  A third witness said at approximately 9:20pm (08/18/18) that he observed what appeared to be an unoccupied pontoon boat approximately 100 feet from the island near County Highway X. Witness stated that the boat did not have lights on and it was at night.  Witness also said that he remembered seeing the boat at the launch around 1pm that day.
  
  Lastly, another Witness who works at the boat launch stated that he observed the two male victims launching the boat with the dog on 08/18/18. Witness said he was notified the following day by another person that the boat was washed up on shore, so Witness went down there to tie the boat up and contacted the Sheriff's Department.
  
  It is unknown how or why the Operator and Passenger left the boat.  Neither the Operator or Passenger had a personal flotation device on when they were recovered.
  
  
  Autopsy results for the Operator were negative for alcohol/drugs.  Autopsy results for the Passenger positive for ethanol (260 mg/dl), blood alcohol concentration (0.260 g/100 ml)
