On 09-02-2013 at approximately 3:30 PM, I drove to Operator''s residence.  Parking in the driveway, I walked up to the front door and knocked.  Operator answered the door.  I identified myself to Operator and confirmed his identity.  I asked Operator if he was involved in an accident on the Mississippi River.  Operator advised he was.  I asked Operator why he had not reported the accident to the IDNR.  Operator advsied he reported it to Rock Island Arsenal Fire Department.  Operator said he thought that was sufficient.
     I asked Operator if the accident had occurred on 06-07-2013 at approximately 9:58 AM.  Operator agreed it did.  I asked subject whose watercraft was involved.  Operator advised it was his jon boat that sank. I asked Operator what happened.  Operator advised he was going fishing on the Mississippi River near Arsenal Island.  Operator said the river current was very strong that day.  Operator told me that he anchored his watercraft bow (up stream) and then put in a stern anchor.  Operator advised that after he anchored the stern, he began to work on his batteries.  Operator told me that the bow anchor let loose and the bow of the watercraft swung out toward the main channel (deeper water).  Operator advised that after the bow of his watercraft swung to the "down stream side", his stern anchor took hold.  Operator advised that the stern of the watercraft was drug down and immediately began taking on water.  Operator told me that both he and passenger put PFDs on.  Operator advised that after the watercraft became swamped, it sank.  Operator advised that he and passenger floated out of the watercraft and swam to shore.  I confirmed with Operator the location of the accident.    
     I asked Operator if anybody was injured.  Operator advised nobody was hurt.  I asked Operator if they recovered the watercraft. Operator advised the watercraft was recovered the following day.  I asked Operator if they had insurance on the watercraft.  Operator advised they did.  Operator told me he received $1200.00 for what was considered to be a "total loss".  I asked Operator to write me a statement.  Operator agreed (statement attached to supplemental report).
