Joan Marchetti was found by firefighters in the kitchen of her small single-family home on Townhill Lane.
Firefighters battle heavy smoke and flames at a house in Green Township.
But crews were unable to quickly enter the house because parts of the floors had collapsed. Mrs. Marchetti's body was found about two hours after the fire started. Mrs. Marchetti, who lived there with her husband, Mike, was the only one home when the blaze broke out, Green Township Fire Lt. Michael Nie said. Officials said the Marchettis have several grown children.
