       On 06-24-2010 at approximately 4:20 PM, Chicago Police Marine Unit received a call of a boat on fire, Lake Michigan at coordinates 41 45.88 N and 087 32.45 W . In the area of 7900 South on Lake Michigan. 
       Chicago Marine Unit boats M-1, M-2 and Chicago Fire Boat  #688 arrived on the scene to find the boat fully involved in fire. 
The three persons on board the boat jumped overboard to escape the flames and were rescued by a pleasure boat named (Pacman).
       The Marine Unit and the Fire Department boat extinguished the fire. The boat was burned down to the hull. M-2 towed the boat to Jackson Park Harbor Pump Out Dock, where the boat sank. Bouy and oil barriers were placed around where the boat sunk , and the owner of the boat was transported to University Of Chicago Hospital by Chicago Fire Department  Ambulance # 38. the owner was treated for  smoke Inhalation and the other two victims refused Medical treatment.
        On 06-25-2010, Boat US, a tow service, was able to raise the sunk boat and towed that boat to Crowley Yacht Yard , and put in dry dock. Crowley's is located at the Calumet River at 95th Street, Chicago. 
         On 07-02-2010, at 11:45 AM, I,CPO arrived at Crowley's and observed the owner boat . I immediately put evidence tape around the boat with yellow tags. I called the Illinois State Fire Marshal's Office and requested assistance. At 2:00PM, Investigator arrived at the scene and I advised him what had happened. 
          I called the owner by phone for verbal consent to  board his boat. While I had the owner on the phone, I asked him a series of questions relating to the operation of the boat. the owner said the engine was running in gear when he observed white smoke coming from the cabin area. the owner said that the only work done recently was a Stereo System was installed by Best Buy Geek Squad, Lansing Illinois. Employees from that company came to his boat on three separate occasions to install the system, each time a different employee tried the installation. the owner said he did not know if marine type wiring was utilized in the instillation. Any mechanical / electrical work done two years earlier was done by Marine Services Corp. 
           I asked the owner if he had tried to fight the fire and the owner said yes. I was unable to find any used fire extinguishers on the boat.
           The State Fire Marshall and I traced exposed wiring from the stereo system back to the batteries at the stern of the boat, but were unable to locate any fuse. The fire might have started from the stereo system, but that cannot be positively determined. 
           The  Progressive Insurance Agent, have advised this officer that the official cause of the fire is undetermined. The Progressive Insurance Company sent a letter to the owner indicating that their investigation of the boat fire of June 24th,2010 indicates that another party is responsible for some or all of the damages. (See Supplemental Report).
