RedactedNarrative: On 11/07/2015 at approximately 1:30 p.m., I, CPO was notified by Sgt. of a Carbon Monoxide Poisoning accident on a boat.  The boat was docked on Otter Creek at the Illinois River. This is next to a cabin known as the Greenwood Club.   
  
       I was advised the subject identified was found unresponsive on his boat approximately 1:00 p.m.  He had arrived the evening before.  They had visited and drank alcoholic beverages.  At approximately midnight Victim went to his boat to sleep.  The next morning  at approximately 6:30 a.m., Subject1 woke up and notices the generator running on the boat.  Around 10:00 a.m., Subject2 went to the boat to wake up Victim. Victim did not respond to knocking on the door or window. Subject2 stated he assumed Victim was " sleeping it off".  Subject2 stated he heard Victim snoring. The generator was still running.  
  
       At approximately 12:30 p.m., Subject1 advised me he came down to the boat.  He tried to wake up Victim by yelling and sounding the boats horn. The door was opened, and he entered the cabin.  The generator was still running.  The heater in the cabin was on.  Victim was wearing 2 jackets and covered with a blanket.  They shook him and splashed water on him.  He didn''t respond.  Using a cellular phone, they called for Subject2 to come down.  Subject2 is an EMT with Bethalto Fire Dept.  While waiting for Subject2 they shut off heater and generator.  One person noticed the thermometer in the cabin indicated 80 degrees.
  
       Subject2 stated he was called to the boat about 1:00 p.m.  He went to the boat and tried to wake Victim with a "sterno rub".  He advised someone to call 911 and request an ambulance. 
  
       The Jersey County Sheriff Department received a 911 call at 1:01 p.m. requesting an ambulance.  The Jersey Community Hospital Ambulance was dispatched. They had transported Victim to the Jersey County Hospital before I arrived.  I contacted the hospital and was advised he was being flown to a hospital in St. Louis to be treated for Carbon Monoxide Poisoning.
  
       The boat was left moored to the dock.  Sgt. and I sealed the doors and windows with evidence tape.  Boat accident investigators were contacted. 
       Photographs are on disc.  The victim passed away on 1/18/2016.
