RedactedNarrative: On Sunday July 10th, 2016, I was traveling north on Kentucky Lake near Richland creek. I was approached by a vessel operated by Operator1, and he advised that a male subject (Tuber1) he had been pulling on a tube had been thrown from the tube and failed to resurface. We proceeded to an area just inside the mouth of Richland Creek where Tuber1 was last seen, and I radioed for more help. Operator1 informed me that he had been under approximately 20 minutes, and the current time was 16:39. All occupants of the vessel insisted that Tuber1 was wearing a lifejacket at the time he went under. The Humphreys County Rescue Squad soon responded and we proceeded to attempt to locate the missing individual. 
  
  Based on statements given by the 8 other occupants of the vessel, the boat had been heading at a slight angle toward the north bank of Richland Creek at the time of the initial incident. Operator1 was the driver of the boat. He turned the vessel left and the tube crossed the boats wake to the right and flipped. Tuber2 and Tuber1 were on the tube. Tuber2 stated that he impacted Tuber1 as the tube flipped and that Tuber1 never resurfaced. 
  
  The search for Tuber1 lasted through the night and the following day, and every possible tactic was used in the recovery. At approximately 20:13 on July 11th, 2016, the body of Tuber1 was recovered several hundred yards south of the area where he was last seen. He was wearing a wakeboarding impact vest at the time of the recovery, which was not a U.S. Coast Guard approved personal flotation device. The Medical Examiner's report shows Tuber1's cause of death to be accidental drowning, and notes a bruise on the left side of the neck. Toxicology results, done in conjunction with the autopsy, show positive for ethanol (24mg/dl) and THC (30ng/dl).   
  
  The vessel involved in the accident was a 24 foot Malibu Wake Setter, owned by Operator1's father. On inspection of the vessel, I found a total of 16 U.S. Coast Guard approved lifejackets, as well as all other required safety equipment. There were no noticeable drugs or alcohol on the vessel during initial contact or during the inspection, but Operator1 consented to giving a blood sample for testing. The results from Operator1's drug and alcohol testing came back negative.
