A home along the River Road in Orrington was engulfed in flames early Friday morning.Crews from Orrington received the call around 1:30 that flames and smoke were coming from the rear of the building, and that people were evacuating the structure.Crews from Bucksport, Holden, Dedham, Brewer, and Winterport joined Orrington in the effort.And when the crews arrived on the scene the flames were already showing. “We came into the scene. The rear of the house: there was fire shooting through the roof, could visibly be seen over a mile away. Very heavy involvement. The guys were very aggressive in their attack, and knockdown,” Said Orrington Fire Chief Mike Spencer. “From what I’m to understand, everybody did get out. There is some smoke inhalation, and they are at the hospital. I guess they went under their own power.”The Fire Marshal’s office has been called in to determine a cause.
