(Hamilton)--Firefighters continued to hose down hot spots Sunday at the scene of a Halloween night fire that caused heavy damage to the former Beckett Paper Company building at Martin Luther King and Dayton Street. Police say MLK will be closed between Dayton and Heaton Streets at least through Tuesday because of concern about a possible wall collapse. Fire Chief Steve Dawson told WMOH Radio at the scene that the area of the plant that burned may have to be demolished. No cause has been listed yet.
