RedactedNarrative: The watercraft was being operated in the center of the river just south of the Ferry Bridge. The operator told his son that he was "going to try to trim the motor in his boat." Witness reported the boat was traveling downstream going approximately 80 MPH when it apparently collided with a tree branch in the river. The boat flipped over numerous times coming to rest upside down. The victim was removed from the river by his son (who was in another boat) and brought to shore where CPR was started. The victim was pronounced at the scene. It is unknown if the victim had been wearing a life jacket.
