Investigators say they’ll probably never know what started a truck fire in Gardiner that spread to a mobile home, threatening a family of five. Crews were called to Buck’s Lane just before 10 o’clock last night for a truck on fire. By the time crews from West Gardiner, Richmond and Augusta arrived, the flames had already reached the mobile home near by. Fire fighters say everyone inside, including three people with special needs, were able to make it out safely. We’re told the owner, Amy Buck, should be able to salvage most of the belongings. Fire officials say the truck was too heavily damaged to determine what caused the fire.
