RedactedNarrative: On Monday September 26th, 2016, Hamilton County Sheriff''s Office was contacted by concerned family members about two overdue or missing boaters that left Big Ridge Marina Saturday September 24th, 2016.  The SO dispatched their patrol vessel who located the boat in a slough near the Wacanda Point bluff on Chickamauga Lake around 10:45 am.  Upon searching the cabin vessel, HCSO Sgt. located 2 victims along with a dog deceased in the cabin area of the boat.  TWRA officers and investigators were requested to respond and investigate the boating incident.
  
  TWRA officers found the vessel’s onboard generator to be running with the air conditioner on in the cabin compartment of the vessel.  All windows, doors, and hatches were secured in the closed positions upon arrival of responding officers.  TWRA requested HCSO Crime Scene Detective to assist with processing the scene.  The Hamilton County Medical Examiner also sent an investigator to the vessel for assistance.
  
  The investigation identified a leak in the on-board generator's exhaust system in the engine compartment due to lack of maintenance and heavy rusting. This leak, coupled with an unsecured hatch that lead from the living quarters to the engine compartment allowed exhaust gases to move from the engine compartment through the hatch and accumulate in the cabin area.
  
  Upon receiving the medical examiner's reports, it is apparent that both individuals and likely the dog, died of accidental carbon monoxide inhalation sometime during the evening/night hours of 09/24/2016.
