Two volunteer firefighters who already have been charged with arson now face more charges after authorities say they have evidence of the men setting other fires.
Zane Snyder, 19, and Charles Jacobs, 35, have been charged with setting three additional fires in Montour and Northumberland counties earlier this year.
According to police, the two men have admitted they are responsible for setting six fires and trying to start a seventh.
State police fire marshal Norm Fedder said he hopes to file more charges by the end of the week.
Snyder and Jacobs are scheduled for court in May.
