RedactedNarrative: On saturday, march 17, 2018, at approximately 1515 hours, while at the canyon lake aid station, i was contacted by an unknown male subject who advised an unmanned jet ski had run aground and crashed into a divider, chain link fence located on the east side of the palo verde boat ramp.   
  
  Upon responding to the location, i observed a 2017 red / white yamaha water craft resting on top of a downed chain link fence, on the shore, approximately twenty feet from the waterline.  In addition, i observed two male subjects, the owner of the jet ski and his employee who were attempting to load another jet ski onto a trailer; which was identical to the one observed on the shore.
  
  Upon contacting owner and subject1, i inquired if the jet ski on the shore belonged to them.  In response, owner stated the watercraft was in fact his and that while attempting to prep the involved jet ski for operation, the vessel unexpectedly accelerated away towards the shoreline; ultimately crashing into the note fence.
  
  During the course of speaking with owner and subject1 reference the incident, they advised the jet ski involved in the accident was in fact unmanned / unoccupied at the time of the incident.  According to subject1, he was sitting on the watercraft that was in the process of being loaded onto the trailer at the time of my arrival.  While sitting on the non-involved watercraft on the main body of water, about twenty feet from the shore line,  subject1 leaned over and started the jet ski.  Immediately upon the engine starting, the involved jet ski accelerated in a northeast direction away from subject1 at a high rate of speed; ultimately striking several boulder clusters on the south shore line.  After striking the boulders, the vessel then jumped onto the shoreline before colliding with the chain link fence, knocking the fence over.  The jet ski then came to a stop on top of the downed fence.  
  
  Upon examining the damage to the watercraft, the front and bottom portion of the craft sustained significant fiberglass damage.  Per the estimate provided by owner, if the watercraft was fixable, the cost of repair was estimated at about $2000.00.  If the damage was unable to be repaired, the total loss value was estimated at approximately $12,000.
  
  During the contact with owner and subject1, there were no signs of impairment or intoxication.
  
  The vessel was left at the scene and later towed, by owner, from the area
  
  Per the damage and the information provided by both subject1 and owner, the accident appears to be the result of the throttle being open during the ignition process and the lack of a kill switch lanyard being attached to an occupant of the vessel.  
  
  No further information to note at this time.
