RedactedNarrative: This is a final summary based on the statements from those involved and physical evidence collected during the investigation to date:
  On July 29, 2017, an AVALON pontoon with 10 persons on board was traveling upstream on the Big Sandy River near Sulphur Branch Creek.   The group was having a bachelorette party and consuming alcoholic beverages.  There was a male designated driver.    
  At or around 1326 hours, an occupant announced that the vessel needed to stop so someone could urinate and the operator put the engine throttle in neutral.  Due to a strong north wind, the AVALON continued making headway at 2 mph.  Without notifying the operator, one occupant jumped from the front of the AVALON into the water, was struck by the vessel and surfaced behind the AVALON.  The injured occupant was loaded on board the AVALON and taken by private vehicle to Henry County Medical Center and later transferred by helicopter ambulance to Vanderbilt Medical Center where she was treated and released.
