The State Fire Marshal's Office has officially ruled the Wednesday fire that destroyed a Lancaster Road warehouse full of paper as "Undetermined" at this time.
Initial reports are that there was burning cardboard on the north side of building, and findings are consistent with the burning cardboard igniting the paper materials inside the building.
investigators have concluded their on scene investigations, but the investigation remains open.
Meanwhile, fire crews were dispatched back to that location Friday after some "hot spots" rekindled.
