RedactedNarrative: On 08/05/17 at 1315 hours, Deputy and I responded to S. B. Cove reference to a Boating Accident with Injuries. Upon our arrival, we made contact with subjects at the Yellow Cliffs Boat Ramp who were attending to a male subject. Victim had severe facial injuries from being stuck by another watercraft (Vessel #1) while he was operating a personal watercraft (Vessel #2).
  
      According to witnesses, after Victim was struck by Vessel #1, Vessel #1 left the area while other Samaritans were tending to Victim. I interviewed one of the witnesses, a female subject, who advised that while she and Victim went out on the lake, her operating a separate PWC, they started heading south in the main bay of the lake and while traveling south and after operating Vessel #2 in circular patterns, she observed Vessel #1 collide with Vessel #2. Other subjects who were on scene and who assisted in the medical care for Victim are listed on the report but did not observe the actual collision.
  
      The description Vessel #1 that was given to MCSO personnel by witnesses and Witness1 was a silver or gray fishing watercraft with a black Bimini top with cursive wording on the side. Witness1 advised that she did not see what the writing was but it was on the side of the vessel. 
  
      Victim was later transported to the Maricopa County Medical Center in serious condition by Air Evac 12Medical Helicopter.
   
      MCSO Helicopter / Fox 1 searched the entire lake and the other watercraft was not located. 
  
      The Accident Investigation was then turned over to the Maricopa County Sheriff''s Office / Lake Patrol Division.
  
      For further information refer to Maricopa County Sheriff''s Office Event #17194769.
    
     There is nothing further at this time.
