RedactedNarrative: On December 14, 2020 at approximately 02:15 AM I received a phone call from TWRA officer about a possible boating incident that had occurred on Nickajack Lake, in Marion County, TN.  Upon arriving at the marina officer and I took our patrol boat out to the TVA boat ramp close to the incident location.  We loaded up a Marion County Rescue Squad member and proceeded to the houseboat that was the incident location.  
  
  We attempted for a few minutes to make contact with any individuals on the boat by yelling and knocking on windows.  Officer and I made entry on to the houseboat and located subject1.  She was located in the back bedroom and was shivering complaining of being cold.  
  
  She told us that Victim was trying to get into the houseboat because the smaller boat that was being used as a tender was sinking.  She told us he had tried to step into the houseboat and fell into the water.  Subject1 attempted to rescue him by throwing him a buoy but was unsuccessful and Victim went under the water and never resurfaced.   
  
  Officer took the patrol boat back to the TVA ramp to get EMS personnel to check Subject1 for injuries or medical issues.  After checking her out it was determined that she needed further evaluation so she was sent to Parkridge West Medical Center.  Captain brought the ROV unit to the site and we were able to find Victim in the water next to the houseboat.
  Per USCG Request - Drugs were noted in the system of the operator during autopsy)
  (Per USCG Request - Vessel 1 had just returned to Vessel 2 and was tying up/attempting to Moor to the vessel when the operator stepped toward V2 and fell in.  Rescue attempts were made, but unsuccessful)
