RedactedNarrative: On September 4, 2021 at approximately 1318 hours I, Game Warden 1 was on patrol, via boat, on the Colorado River located in the vicinity of Laughlin, Clark County, Nevada. I was doubled with Game Warden 2. 
  
  At this approximate time, we were notified by a passing by Personal Watercraft (PWC) that an accident had taken place south of Community Park, north of our current location. The driver of the PWC stated that two PWC's ran into each other and one of the drivers was hurt and asking for help. Upon our arrival, at approximately 1320 hours, we noticed a blue in color PWC with one driver and one passenger. The driver was holding the handlebars to another PWC (unmanned) that was missing the seat. The driver was a white male with medium length brownish hair. The passenger on the rear was hunched over. We were later informed that the male passenger was the driver of the unmanned PWC and had been hit by another PWC and ejected into the water. We had the driver bring the unmanned PWC to our vessels port (left) side and the driver then went to the starboard side. I secured the unmanned vessel and went to the starboard side to talk to the driver. 
  
  Upon getting the hurt occupant off of the other PWC it was apparent that the occupant needed immediate medical attention. He was transported to the closest dock and transferred to the waiting ambulance. The driver of Vessel 1 was never found. 
  
  The ambulance took the occupant, V1 Operator to the closest hospital. I arrived at the hospital and talked to an ER doctor who informed me V1 Operator would be flown to a trauma center due to the injuries. V1 Operator had a broken pelvis, broken ribs, internal bleeding and a collapsed/punctured lung. 
  
  The vessel that was struck was returned to the rental agency. On September 9, 2021 I was able to talk to V1 Operator in the hospital. V1 Operator stated he was turning around and got struck from his left side. Besides the initial collision he did not remember anything else. 
  
  Nothing further.
