RedactedNarrative: At approximately 1:30 P.M. on Sunday, June 14, 2015, Vessel One was towing a tube on which the victim was riding.  Vessel one struck a wake, which in turn caused Victim to fall from the tube into Norris Lake.  Victim was not wearing a personal floatation device (PFD). When Operator saw that the victim had fallen from the tube, he circled the vessel back around to render aid.  While approaching the victim, Operator saw the victim go underwater at which point he (Operator) obtained a PFD to throw to Victim.  The PFD did not go far enough and the victim went underwater.  Operator dove into the water to attempt to save the victim, but Victim had already went under.  Operator yelled for help during the ordeal, which nearby neighbors heard and were able to call 911.  After Operator''s unsuccessful attempt to save the victim, he pulled the vessel to shore, where he sat until first responders arrived.  The victim''s body was recovered at approximately 8:05 P.M. 
  
  Blood draws were obtained from both the operator as well as the victim and samples forwarded to the Tennessee Bureau of Investigation for analysis.  Results will be included in this report after analysis is concluded.
