RedactedNarrative: On 08/03/14 at 1311 Deputy and I were working uniform patrol on board our fully marked Maricopa County Sheriff''s Office patrol watercraft, when we were dispatched to the Agua Fria River reference to a single boat accident with injuries, involving a personal watercraft. The information that we received from MCSO dispatch was that a PWC (Vessel #1) had exploded, and the occupants, which consisted of two children, were ejected off Vessel #1 into the lake. We advised MCSO dispatch that we were enroute. 
      While we were attempting to locate the occupants of Vessel #1 in the Agua Fria River, we learned that Peoria Fire Boat 199, who were also enroute, met with the occupants of Vessel #1 on another vessel and transported all three subjects to the Castle Creek Boat Ramp. All three occupants were picked up by an unknown boater who met with Peoria Fire and transferred them onto Peoria Fire''s Vessel. 
      Once we learned that Peoria Fire Boat 199 were enroute to the Castle Creek Boat Ramp with the three occupants, Deputy and I made our way over to the boat ramp where we met with Peoria Fire Department personnel. Two of the occupants, who later identified themselves to Deputy at the North Peoria Emergency Center both suffered first and second degree burns to both of their legs from the explosion of the PWC. All three occupants were transported to the North Peoria Emerency Center for non life threatening injuries. 
      Deputy and I made our way over to the Pleasant Harbor Marina where Vessel #1 was towed by the unknown boater. Upon our arrival, I took digital photographs of Vessel #1 (see attached photos).     
      Operator said that while she was making her way south out of the Agua Fria River onboard Vessel #1, with victims sitting behind her, they were having problems with the acceleration of Vessel #1. Operator said that the maximum speed was only 5 mph and she could not go any faster than that speed. Operator said that while they were making way south, Vessel #1 then suddenly exploded throwing both into the lake. Operator said that subjects, who were on another Vessel, saw that they were in distress and stopped to help. Operator said that Peoria Fire Department onboard Peoria Fire Boat 199 arrived on scene where they transported them to the North Peoria Emergency Center.
      I transposed the photographs onto a CD and later transported the CD to the Anthem Substation Property and Evidence room. 
      There is nothing further at this time.
