WARREN — A Youngstown man has pleaded not guilty to two counts of first-degree felony aggravated arson and one count of second-degree felony aggravated arson.

Austin M. Dunmire, 26, of Dearborn Street, Youngstown, was arraigned Wednesday in Trumbull County Common Pleas Court before Judge Sean J. O’Brien.

Dunmire was arrested after an investigation by the Ohio State Fire Marshal’s Office in late June. When he appeared in Girard Municipal Court his bond was set at $250,000, as it remained following his appearance in common pleas court.

On June 21, the Girard Fire Department was called to a structure fire — the report indicates that fire crews were quick to extinguish a bulk of the fire from outside before making their way inside. Crews pulled at least one cat from the residence.

People living in the home told investigators that Dunmire had prior altercations with a woman there. Just before the fire, they said she had spoken on the phone with Dunmire when he threatened to “light their house on fire,” a report states.

The occupants told investigators they had been asleep when shouting and banging on their door from neighbors awakened them. Outside the home, they saw a piano on their back porch that was set on fire that expanding across the porch and house.
