According to authorities a fisherman died after another boat rear-ended his boat Sunday shortly after midnight, throwing him into the Cal-Sag Channel in the south suburbs.

Coast Guard Petty Officer Nathaniel Parks stated that the accident occurred when the second boat swerved to avoid a log and hit the fishing boat, which was moving.  The man in the fishing boat was thrown into the water and could not swim.  He was not wearing a life jacket.

According to state officials at least one boat was conducting maintenance tests at the time of the collision.

The victim has been identified as a 41-year-old man from Orland Park according to the Illinois Department of Natural Resources. The victim’s name has not been released yet and is pending identification of family members.

The body was found using helicopters with an infrared camera in addition to divers with sonar.  The fire departments helping to find the body were from Chicago, Alsip, Palos Heights, and Blue Island.

The Illinois Department of Natural Resources is investigating the collision and will determine whether any of the boaters will be cited.
