RedactedNarrative: On Monday, May 30, 2022 at 1829 hours I was dispatched to a 2 vessel collision involving a deck boat and a jet ski on South Holston Lake in Sullivan Co., TN.  
  
  The deck boat was traveling upstream with the jet ski following.  Both vessels made a u turn and the jet ski came along the left hand side of the pontoon and abruptly made a 90 degree turn to the right in front of the deck boat which hit the jet ski sending both occupants into the water.  
  
  A nearby vessel retrieved the occupants from the water and took them to the 421 access area boat ramp.  The driver of the jet ski sustained serious injuries and was life flighted while the passenger was transported by ambulance where she was pronounced dead.
