RedactedNarrative: On 07/04/2014 I, TWRA Officer, was on patrol on Old Hickory Lake with Officer. We were patrolling in the Drakes Creek area when I heard a call on marine channel 16. The caller on marine channel 16 requested immediate assistance from TWRA in the Skinny Dip area of Old Hickory Lake, Sumner County. Subject described a possible missing person. She advised a PWC had rolled over on a man on a float. This call on marine channel 16 took place at approximately 14:45. I immediately notified TWRA dispatch of the situation. I requested dispatch to notify Hendersonville Fire Department of the situation and location of the event. I requested for assistance of other TWRA officers on patrol. At this time proceeded to Skinny Dip location with emergency lights and siren on. It took Officer and I under 10 minutes to arrive. 
  
  Upon arrival I located witnesses nearby. I asked where the victim had last been seen. At this time Officer and I put out a perimeter of orange marine markers. The perimeter was set in accordance of witness observations of where the victim was last seen. Upon completion of this perimeter the first HFD boat with rescue divers arrived on seen. I notified HFD personnel of the marked perimeter and this is where divers focused their search. At this point all other search for the victim was turned over to HFD and Sumner County Emergency Management Agency. 
  
  At this time Officer and I, with the help of TWRA Officers, started collecting statements from witnesses. Three boats were located around the accident containing witnesses. These were the first to be interviewed. During this process contact was made with Operator1, PWC driver, and the PWC owner. Both were located on the boat “Snapshot”. “Snapshot” was the boat operated by Subject, who originally made the call on marine channel 16. Officer and I asked Operator1 and Owner to board our patrol boat. At this time Officers continued to take statements from witnesses. Additionally Officer and I took possession of the PWC involved in the accident. Interviews were conducted at this time of Operator1 and Owner. 
   
  According to their statements a group of friends had rented a pontoon boat that day. They had taken the pontoon boat to Skinny Dip and anchored it at a nearby island. In addition Owner had brought his PWC and Victim had brought his fishing boat. All three vessels were located in the same area by a nearby island. Over a period of time Victim had become separated with his party. He had lain on a rectangular, blue pool float. During this period of time while on the pool float he floated away. Victim was not wearing a personal floatation device (PFD). According to accounts he may have floated up to 200 yards away from their party. 
  
  Next according to statements Operator1 asked Owner if he could borrow the PWC to retrieve Victim. Operator1 put on a PFD took the PWC to Victim. According to an account from Operator1, Operator1 approached Victim at an idle speed. Victim reached onto the left side of the PWC toward the middle of the vessel. He held on for approximately 5 seconds before, unexpectedly to Operator1, Victim tried to board the PWC. According to Operator1, Victim reached onto the back of the PWC directly behind the seat. As Victim tried to climb on the PWC rolled to the left toward Victim. According to accounts the PWC rolled over to the left and both Victim and Operator1 went into and under the water. The PWC rolled to an upside down position in the water. At this point Operator1 resurfaced and rolled the PWC to an upright position. Operator1 stated that he then noticed that Victim, who was not wearing a PFD, had not resurfaced. According to other witness accounts Operator1 looked “frantically” for Victim.
