RedactedNarrative: At approximately 14:00 hours on 5-25-2014 a group of individuals were swimming behind a pontoon boat in Cove Creek on Norris Lake, upstream from the Norris Dam.  Eight individuals were in the water swimming while two remained on board.  The vessel was not at anchor and as a result began to drift towards the bank.  One of the individuals on board alerted those in the water that she would be moving the boat away from the shore.  Operator states that she started the boat and almost immediately heard screaming from the water at which point she immediately shut the motor off.  The individuals in the water state that after the boat was started that it began to come backward slowly, striking victim and once they began screaming the boat then went forward rapidly.  See witness statements.
