RedactedNarrative: I responded to a boat grounding that was reported on the SW side of Eight Mile Island on Priest Lake. When I arrived the vessel was not at that location so I circled the island to see if it was in a different area and was unable to locate the vessel. I contacted Copper Bay Salvage and asked them if they salvaged a vessel from the island and they said that they did. I asked for the boat owner's information and where they took the boat and they gave me that information. I contacted the boat owner, identified as Owner, and asked him what happened. He told me that he had contacted his lawyer. I asked him if there were any other people on board his boat at the time of the incident and he told me that his girlfriend and two other friends were on board.  Owner refused to provide any other information about the incident to include the operator's information, passenger names or what caused the accident to occur. I then went to Priest Lake Marina and found the boat with significant damage to the under side of the boat. Pictures and a video were also taken at that time.
  Due to lack of cooperation by the vessel owner (Owner) in this investigation, the sequence of events leading up to the accident are unknown and information herein is based solely on observations made during the investigation and/or by the investigating officer.  The date and time of the accident identified in this report is the time the accident was reported to the Bonner County Sheriff's Office by an uninvolved party as the time of the accident is unknown but likely occurred during the hours of darkness between the evening of 09/01/2022 and the morning of 09/02/2022.
  Owner failed to provide any information about the accident and claimed no injuries.
