RedactedNarrative: Two subjects were supposed to be on a 24 foot Sea Ray cabin cruiser boat. Their last known location was somewhere near the Two Mile Island chain. The subjects had not been heard from in over twenty four hours.
  
  Cpl. and Ranger located the vessel around midnight. The vessel was anchored near an island across from Two Mile Creek Park. Both occupants were found deceased in the cabin.
  
  (Cpl. informed me later the cabin hatch was closed when he initially boarded the vessel. He opened it and found the victims.)
  
  RFC and I transported Forsyth County Sheriff's Office (FCSO) investigators to the scene by vessel. The investigators boarded the victim's vessel and took photographs and notes for their case file. The victim's vessel was towed by Tow Boat U.S. to Vann's Tavern Boat Ramp. Once at the boat ramp, the victims bodies were removed by Forsyth County Coroner's Office personnel. The bodies were taken into custody by the Forsyth County Coroner's Office for autopsy.

  On May 30, 2018 I traveled to the FCSO impound lot. On board the vessel, I observed all of the cabin window vents were closed and secured with their designed clasp inside the cabin. 
  
  I located a portable generator inside the engine compartment. The generator was in the "start" position and switched "on". (Cpl. informed me the generator was not running when he located the victims on May 28, 2018.)
  
  I did not immediately notice any type of carbon monoxide or smoke detector inside the cabin.

  On July 9, 2018, I received a copy of Georgia Bureau of Investigation (GBI), Division of Forensic Sciences, lab reports. (The FCSO investigators requested a carboxyhemoglobin determination from the GBI). 
  
  GBI Forensic Toxicologist indicated the following in his reports:
  
  Victim 1- Presence of carboxyhemoglobin ; 67% saturation (+/- 3)
  Victim 2 - Presence of carboxyhemoglobin ; 73% saturation (+/- 3)
  
  The determinations were made using multiple blood samples from both victims. A copy of the GBI lab report for each victim is included in the case file.
