RedactedNarrative: On Sunday 5/27/2018 at approximately 1848 hours, the Maricopa Co. Sheriff''s Office (MCSO) received reports stating two personal watercraft (PWC) collided in the main bay of Apache Lake, just south of the resort and beyond the buoy line.  Reporting parties stated all four total occupants of the two involved vessels had been ejected into the water and were injured.  All occupants were picked up by a Good Samaritan who placed them on his boat awaiting rescue.
  
  MCSO personnel arrived to the scene at about 1859 hours and provided emergency medical services for the injured parties.  All persons on the crashed vessels were transported to regional trauma centers for their injuries.  Three air-medical helicopters were summoned to the MCSO Apache Lake Aid Station to transport the three most seriously injured children.  The fourth injured child was transported from the lake by ground ambulance.
  
  Both PWC are owned by the same person.  Owner permitted his 13 year-old son Operator2 to operate a black and white Sea Doo.  V2 sustained moderate right-sided bow damage in the crash.  Owner also permitted his 14 year-old nephew to operate his other PWC which sustained heavy damage to the entire bow and handlebars.
  
  The exact circumstances of the crash are unknown.  No witnesses to the crash itself were located or identified.  The four total children onboard the vessels sustained head injuries with some extent of retrograde amnesia, so I was unable to ascertain the sequence of the crash from the passengers.   However, based upon the serious mechanism of injuries, and extent of damage to the yellow watercraft, excessive speeds were determined to play a factor in the collision.  Operator2 later told another Deputy he and Operator1 were operating the two PWCs in a nearly parallel manner, maneuvering the vessels to splash one another.  At some point, Owner said one of the PWCs crossed into the path of the other resulting in both vessels capsizing and ejecting all occupants into the lake.
  
  Every passenger was found to be wearing an appropriately-sized personal flotation device at the time of rescue.  All passengers were accounted for and taken aboard a passing boat within moments of the crash.  There were no indications of drug or alcohol impairment in this incident.  None of the PWC operators had attended a boating safety class, per their parents.  Additionally, none of the operators were known to have substantial experience operating watercraft.
  
  Follow-up reporting from emergency medical services revealed all passengers survived the incident.  However, total injuries from this crash consisted of multiple fractures, lacerations, and concussion-type symptoms suffered by the victims.
  
  This ends the brief synopsis at this time.  For more detailed information, please reference MCSO Incident Report: IR18015531.
