Investigators in Mooresville are trying to determine who started a McNeely Avenue fire yesterday afternoon.
Deputy Chief Shane LaCount says it appears the case of arson was contained to a single room of the vacant house.
In a separate case yesterday morning, firefighters were called to a North Center Street warehouse fire.
The blaze was quickly brought under control.
A dock area was destroyed and there were damages inside the building include the attic area.
There were no injuries – that fire has been ruled accidental.
