Fire officials say they are trying to figure out what might have caused a fire at International Paper Company in Lynchburg. Officials say the call came in around 8 p.m. and took 20-30 minutes to put out. The fire started on one of the paper lines, officials add. The plant was fully staffed during the fire and all employees self-evacuated the building. Officials say they are unsure whether the business can operate tomorrow due to not being able to investigate the building.
