Upon arrival of crews, the fire status was changed to a vehicle fire inside the building.
The fire spread quickly and the building was a total loss.
A Pennsylvania State Police Fire Marshal was requested due to the amount of damage and a possible arsonist in the area.
On-call Fire Marshal Trooper Thomas Finn arrived on scene and conducted interviews.
On Sunday, Trooper Finn returned to the scene in the morning to perform his origin and cause investigation.
The fire was believed to have started in a 2008 Ford E250 parked inside the building but the investigation is ongoing and the fire is being considered suspicious.
Anyone with information on the incident should call the Pennsylvania State Police at Schuylkill Haven at 570-739-1330.
