RedactedNarrative: On 07/23/2016, Saturday, at roughly 1830 hours, I received information from TWRA Official#1 concerning a kayaking accident on the Pigeon River in Cocke County, Tennessee, downstream of the Walter's Hydroelectric Plant near the Tennessee -North Carolina stateline. This kayak accident/fatality was actually reported to the Cocke County Central Dispatch at 1406 hours but was not reported to TWRA until later through the TEMA system by Official#2 with Cocke County EMA. The Cocke County Sheriff's Department personnel responded and arrived on scene at 1414 hours, units 750, 714, 736 and other emergency service personnel. While on scene, CCSD Detective#1 interviewed and obtained written statements from 3 subjects. Boater/witness/ victim's friend Witness#1, boater/witness Witness#2 and boater/witnesses Witness#3. None of the 3 witnesses, actually witnessed any events that lead to the victim, Victim#1 coming out of his kayak into the Pigeon River as he entered the first set of rapids after launching at the Duke Energy rafting ramps located on the Waterville Road at the state line. An additional witness, Witness#4 came forward, stating that he saw the victim floating in the river holding onto his kayak before entering the first set of rapids below the launch ramps and as he entered the top of the rapid, he became separated from his kayak. Witness#4 further stated as the victim floated downriver by him he yelled to the victim to swim to the shore which he did not. Witness#4 watched as the victim floated downriver out of sight with a kayaker following behind him. Witness#4 further stated that the victim was wearing a lifejacket and a helmet. Witness#1 stated that after launching their kayaks together at the ramp, he went first downriver ahead of the victim stopping at the bottom of the first rapid, Powerhouse and waited. Witness#1 stated that when he first put eyes on the victim that it looked like he was out of his boat. Witness#1 stated that the victim swam towards his kayak but the water current was way to swift to make it, to the side. Witness#1 stated that he tried to make it to the victim as quickly as possible without risking his own safety. The next time, Witness#1 saw the victim, he was a ways downstream and was not responsive and a group of people were beginning CPR and victim was not responding. Witness#1 stated that the victim had very little experience in whitewater kayaking. Witness#2 stated that he was boating and floating in an eddy and saw someone floating downriver to his location. He paddled over to the floating victim and offered the stern of his raft and the victim was able to hold on. Witness#2 also held onto the victim's paddle. Upon reaching the Waterville Road side of the Pigeon River, the victim became unresponsive and 911 was called. Witness#2 stated that he then left the scene and went to the roadway to wait on responders. Boater Witness#3 arrived at victim Victim#1 after he was pulled to shore. He observed that victim was minimally responsive but not really breathing had a weak pulse and was becoming less responsive. Witness#3 and passenger started CPR, first breaths indicated significant water in the victim's lungs. CPR was continued but the victim remained unresponsive. EMS arrived and transported victim Victim#1 at roughly 1430 hours to the Newport Medical Center by ambulance. CCSD Detective#1 did not collect the victim's kayak, lifejacket or photographs taken. CCSD Detective#1 ordered autopsy on 07/23/2016 and autopsy was conducted on 07/24/2016 at the Knox County Regional Forensic Center, Knoxville, Tennessee.  Results, the probability of drowning.
