RedactedNarrative: On July 22, 2020 at approximately 12:00 PM CST Officers received information stating there was a boat on Lake Cumberland tied to a house boat that had sank during the night. I arrived on scene at 1348 CST accompanied by another officer at approximate GPS location 36 N 54'42" 85 W 01'51". Once on scene I took witness statements from PASSENGER 1 and OPERATOR 1, according to their statements they rented the boat a 1990 Bayliner with KY registration number 0010-WN,  from rental company on July 20th. PASSENGER 1 and OPERATOR 1 put the boat on the water and then towed the boat behind a rented house boat to the location where it sat until July 21st. On July 21st they took the boat out for about an hour and then tied it back to the house boat, when they woke up on July 22nd the boat had sunk. I contacted the boat owner and according to his statements he had told PASSENGER 1 and OPERATOR 1 that they must take the boat off the water each day to drain the water from the bilge. PASSENGER 1 and OPERATOR 1 said that they never received that information from boat owner. OPERATOR 1 also stated that he had turned the bilge pump on the night before, but could not advise if it was working correctly.                                                                                                                                                                                                       
  To ensure that the vessel was not left on the water or abandoned I contacted the Corps of Engineers. The owner of the vessel did not have the finances available to have it towed, and the renters of the vessel refused to pay the tow bill.
  On Saturday July 25th boat owner advised me that he had contacted Marine Assist in Jamestown requesting them to retrieve the vessel from the water, Marine Assist retrieved the vessel on Monday July 27th and stored it. On Wednesday, July 29th, Officers went to Marine Assist to take pictures of the vessel. When taking pictures of the vessel I noticed that there was a bonding agent around the drain hole indicating that there may have been a leak in the hull at some point.  When I was looking in the transom it appeared that the bilge pump was not hooked up, but it is unknown to me if this was a result of the boat sinking or if the bilge pump was not hooked up correctly prior to the incident.
