A Smethport woman died in a house fire early Saturday morning on Route 446 in Keating Township. McKean County Coroner Mike Cahill says that 69 year-old Martha Marsh mostly likely succumbed to smoke inhalation, although an autopsy will confirm the cause of death. Smethport Fire Chief Steve Field says the house was fully involved when he arrived shortly after the first alarm. The home is a total loss and the state police fire marshal is investigating the cause of the blaze. Four fire companies battled the blaze and had to get water from the International Wax Plant in Farmers Valley.
