A River Pines man was transported by REACH air ambulance to UC Davis Medical Center early Sunday morning after suffering burns to his arms and face when his house caught fire early Sunday morning. The first Amador Fire Protection District fire engine arrived within 6 minutes and found the 2-story home fully involved in fire. Due to the extent of the fire, firefighters focused efforts on protecting the adjacent homes before extinguishing the fire. The house, located on Emigrant Trail in River Pines, was a complete loss with minor damage to a second home. Initial reports from neighbors indicated an explosion prior to the fire. The fire investigation is looking into the possibility of a propane leak in the structure. No current information on the occupant’s condition is known.
