RedactedNarrative: On May 21, 2022, at about 1700 hours, I was on patrol inside the Lake Pleasant Regional Park, when an emergency call for service was placed in reference to a watercraft accident. The caller said their friend had lost her leg and was still in the water. The phase 2 coordinates received were 33.911878 -112.27872. After plotting the GPS, it showed the location to be in Cole''s Bay. 
  
  Deputy and I responded to the Maricopa County Sheriff''s Office Boat House and boarded patrol boat LP 39. While responding to Cole''s Bay, we were notified by dispatch the watercraft was a white 33-foot Formula watercraft. The caller stated they were in route to the northern four lane boat ramp at Pleasant Harbor Marina. Another caller stated the motor cut the injured parties'' leg off. 
  
  I diverted from heading to Cole''s Bay and responded to the Pleasant Harbor North 4 Lane, where I observed the white 33-foot Formula watercraft, already docked. I nosed up to the dock and had Deputy get off the watercraft to provide aid and conduct the investigation into the accident. 
  
  Deputy spoke with the operator of the watercraft. Operator stated he was operating the watercraft and pulling a tube behind the watercraft. As he began to slow down, the tube began to "submarine" and the children fell off. He then placed the watercraft in reverse to close the gap between the watercraft and the kids. 
  
  He said as he was in reverse, he saw Subject1 get up and jumped off the back of the watercraft. Operator believed he grabbed the gear shifter to place the watercraft in forward, and accidently grabbed the throttle control and raised the rpms. Subject1 then was struck by the starboard prop, which amputated her left leg at the pelvic bone. Subject1 had lacerations on her right leg and visible bruising from what appeared to be prop strikes. 
  
  I then provided scene security around the dock to prevent another watercraft from entering the scene. Peoria Fire Boat and Peoria Fire Engine arrived on scene at 1718 hours. After Deputy completed the initial investigation, we went out to the GPS coordinates provided on the phase 2. 
  
  The area of the coordinates was an open bay in Coles Bay just outside of the no wake zone buoys. The depth was approximately 88 feet and a water temperature of 75 degrees Fahrenheit.
  
  Subject1 was alert and talking when she was transported to Honor Health Deer Valley by Native Air. At 1846 hours, Subject1 was pronounced deceased by medical staff at the hospital.
