RedactedNarrative: On 12/19/21,  I CPO responded to a boating accident at Ten Mile Creek State Fish and WIldlife Area.  The property is south of Belle Rive, Illinois and is owned by the Illinois Department of Natural Resources.  The boat accident occurred at approximately 12:14 PM and my arrival was 12:53 PM.  I spoke with the owner of the watercraft at the scene.  SUBJECT said himself and SUBJECT2 deployed a canoe into a strip pit there to fish.  They did not wear life jackets and it was later discovered that no life jackets were aboard the canoe.  
  
  SUBJECT said his dog was also on board the canoe.  SUBJECT2 caught a fish and it flipped under his seated position.  SUBJECT2 was trying to obtain the fish and the dog approached and was after the fish as well.  The canoe flipped as a result of the incident.  SUBJECT said he was in the process of swimming to shore and looked at SUBJECT2 swimming on his back in an attempt to get to shore.  SUBJECT said he was encouraging SUBJECT2 to make it to shore.  SUBJECT said SUBJECT2 disappeared under water.  We used a remote sonar boat to locate a target believed to be the body.  Benton Search and Rescue deployed divers and removed subject2 from the water at 4:10 PM.  This incident is pending further investigation.
