RedactedNarrative: On Saturday, February 3, 2018, at approximately 1429 hours, deputies were dispatched to a boat explosion that occurred in the sandy beach recreational area located at the far east portion of canyon lake.  Per the initial information provided, as a result of the explosion, a seven month old child and an adult female sustained burns.  The occupants of a second boat, occupied by friends, were assisting in transporting the injured subjects back to the main bay of canyon lake for medical assistance.
  
  Due to the fact initially obtained information indicated a seven month old child was exposed and burned (to an unknown degree) as a result of the explosion, i immediately requested the immediate response of air evac medical transport to assist.
  
  Upon the response of deputies by mcso patrol boat, eastbound on canyon lake, towards the sany beacharea, i was waved down by a recreational cabin cruiser boat just east of “beer can” recreational area.  Due to the boat travelling westbound from the area of sandy beach, where the incident occurred, i contacted the occupants of the vessel.
  
  In making contact with the occupants of the cabin cruiser, i was advised the burn victimsand occupants of the boat that exploded were on board and in the process of being transported back to the main bay area for medical attention.
  
  At that time, i observed a young, female baby being brought out from the cabin compartment of the vessel.  The baby was crying and appeared to be alert / conscious.  During my initial assessment of baby, i noted a red and blistered thermal burn to her left outer arm.  As a result of my assessment, i was unable to note any further indications of injuries or burns to any other portion of torso, head, face or appendages.
  
  As i was assisting the male subject holding baby, baby''s father, a second , adult female subject was observed exiting the lower cabin compartment of the civilian vessel.  The adult female, later identified was previously noted by mcso radio as being burned in the explosion, was observed to be moving slowly and was visibly in pain.  Victim2 had red, burn indications to the front (anterior) portion of her shins, knees and upper thighs of both her right and left legs.  In order to get more advanced medical treatment for both victim2 and baby, the family were transferred to the mcso patrol boat and immediately transported to the canyon lake aid station in order to meet with responding medical personnel.
  
  Upon arrival at the aid station, and during the course of assisting victim2 and baby into the medical room of the facility, i inquired as to what had occurred.  In response, victim2 and father provided me with the following information:
  
  Prior to the explosion occurring, they were on the 1986 searay, 17 foot inboard motor boat in the sandy beach recreational area of canyon lake with another boat occupied by a group of their friends.  While floating in the body of water located in the “no wake zone” of sandy beach, father who was operating the boat, attempted to start the engine of his vessel to get underway.  In doing so, a loud explosion was heard, originating from the rear boat compartment of the boat; resulting in a fire behind the rear seat of the passenger compartment.
  
  Victim2, who was seated at the back of the boat feeding baby, directly in front of the engine compartment immediately attempted to shield / move baby from the area to avoid baby from being injured.  However, in doing so, baby and victim2 still sustained burns to the previously noted areas of their appendages.
  
  To avoid the resulting fire from spreading throughout the boat, father grabbed the onboard fire extinguisher and deployed the contents to the fire; extingu...
