A fire Monday afternoon destroyed a mobile home in Allegheny Township. Fire crews were called to 252 Cambridge Drive just after 4:00PM. They found flames shooting from the front of the structure. At least one person was at home at the time and was able to make it out. Fire officials say three dogs perished in the blaze. Firefighters had the flames knocked down in a half-hour – but spent about two hours on scene. A state police fire marshal has been called in to investigate.
