Another fire in Elk County has been ruled arson.
The latest fire was reported at 4:20 a.m. Saturday at a house on Lynch Road in St. Marys.
No one was home at the time of the fire that heavily damaged the house.
Last Monday two vehicle fires in St. Marys were ruled arson. Earlier this month the St. Joe’s Club building in Johnsonburg was set on fire. Investigators are still trying to determine whether a blaze at the Old Johnsonburg Hotel was arson.
Fires on June 17 and May 30 in Ridgway were also determined to be intentionally set.
