BANGOR — A 53-year-old Maine man facing an arson charge for allegedly torching a state fire marshal investigator’s car now faces additional charges of setting three fires in Penobscot County.

John Weckerly of Prentiss Township was indicted yesterday on three counts of arson and other charges involving fires that damaged or destroyed a garage, a seasonal camp and other structures near Weckerly’s land in northern Penobscot County.

Weckerly was charged last August with arson for allegedly dousing a car with a flammable liquid and setting it on fire. At the time, the car was being used by a fire marshal investigator who was investigating the other fires.

The Bangor Daily News reported that Weckerly has denied setting the fires for which he was indicted Wednesday.
