RedactedNarrative: On 8/21/2017 at approximately 11 AM, CPO''s received a call of a boater in distress.  Two people called and reported someone moaning and yelling for help.  Caller1 located a person in the water near Rocky Point, SW of the Carbondale boat ramp, on the South Shore of Cedar Lake.  CPO''s located a submerged V bottom boat, near the powerline crossing on the main body of Cedar Lake. The boat was tied to the West rock wall (N37.65474, W089.28021). CPO1 went on shore to look at contents which appeared to have been thrown onto shore.  The boat lacked any visible registration on the bow portion sticking above water. CPO1 secured additional lines to the boat and a brief scan using the sonar was conducted.
  
  At approximately 1 PM, They located Caller1, the witness from the Carbondale ramp. Caller1 used his boat to (IL9322HH) to rescue the person in the water around 8 am.  Subject1 told them operator was on shore near the boat.  
  
  We located the boat and observed only the bow surfacing.  CPOII and Sgt secured a line, to the bow, and towed the boat towards the Carbondale boat launch.  The boat surfaced and the motor cowling was missing.  When we reached the shore the water inside the boat caused it to roll over.  We flipped the boat back over but observed the motor and trolling motor had come unattached.  
  
  We retrieved the 2 motors and placed them in the boat.  We towed the boat onto the ramp and allowed it to drain.  I observed the plug inside the drain and water was still draining out of the boat.  The boat had been painted multiple times and no hull damage was observed.  The boat appeared to have paint transferred from the bow, where it impacted the rock wall, and a small dent on the plate the eyelet was mounted to.   We observed no HIN or registration numbers on the side.  
  
  On 8/24/17 I spoke with Operator and Occupant on the phone.  They stated the following occurred.  On 8/21/2017, at approximately 1230, am Operator was operating a grey unnumbered 15 foot open aluminum motorboat on cedar Lake.  Subject1 occupant was a passenger riding towards the bow of the boat.  The boat was headed South and travelled under the powerlines.  Occupant heard Operator yell the boat was taking on water.  Operator was approximately 20 yards from the Shelter Bluff shore.  He attempted to run the boat onto shore, to prevent the boat from sinking.  The boat impacted a sheer rock wall and the stern of the boat sank into the 15 foot deep water . 
  
   Both occupants jumped into the water and tied the boat to a tree on shore.  The occupants stated all the personal belongings drifted into the water.  Operator dove down to retrieve the battery and gas tank from the sunken boat.  They did not have cell phones and spent the night on the rock wall.  At approximately 8:00 am Occupant aired up a mattress and attempted to make it to the boat launch.  He met 2 individuals in a red canoe who offered to help.  Occupant had retreived a Yeti cooler and the canoers offered to take it to shore for him.  Occupant said they never took the cooler to shore.  Occupant then began hollering for help and was assis…  Alcohol was not deemed to be a cause of the accident.
