RedactedNarrative: On 08/11/16 at approximately 9:40PM, while off duty, I [CPO] received a text message on my personal cell phone from SGT, informing me of a boat fire at the Three Rivers Marina in Channahon.  I arrived at the marina at approximately 10:20PM to find multiple emergency vehicles on scene.  The boat fire had already been extinguished upon my arrival.  I briefly spoke with the Channahon Fire Department.  
  
  SUBJECT, who was uninjured, was the only occupant of the boat at the time of the fire.  SUBJECT''s father and owner of the boat was also on scene.  SUBJECT informed me he had been staying on the boat and had not operated the boat that day.  SUBJECT stated he had been on the boat for approximately 4 hours before the fire started.  SUBJECT stated although the 110 power in the boat was plugged in, it did not seem to be working, as none of the lights inside the boat would turn on.  SUBJECT stated he started noticing electrical issues on the boat approximately 2 weeks prior and he had noticed one of the electrical prongs from the boat was broken off and stuck inside the power cord used to hook up to shore power.  As it began to get dark, SUBJECT lit candles and an old fashioned oil lamp to illuminate the cabin of the boat.  After lighting the oil lamp, SUBJECT went into the bathroom.  While inside the bathroom, SUBJECT stated he felt heat.  Exiting the bathroom, SUBJECT found the cabin to be engulfed in flames and smoke.  SUBJECT exited the boat and called 911.
  
  The boat, which was a 27ft, 1989 Carver Santego, burned to the hull and sunk in the harbor.  I photographed the remains of the vessel, which was covered in fire retardant foam used by firefighters to extinguish the fire.  The two docks on either side of the boat were also damaged by the fire and I noticed a small pvc waterline running below the dock was leaking near the boat.  No other vessels were reported to have been damaged by the fire.  Inspecting the cord used to plug the boat into shore power, I noticed the female end, which would have been plugged into the boat, was badly scorched and melted around one of the prong holes.  Examining the other end of the cord, I noticed similar black scorching marks around a single prong as well as at the electrical box where the boat was plugged in, around one prong hole of one outlet.
  
  SUBJECT''s father and owner of the boat, stated he had purchased the boat about a year and a half ago for $10,000, but the blue book value at the time was probably only $8,000.  The boat is a total loss.  The owner of the marina estimated the damage to the docks to be somewhere between $1,200 and $2,000.
