Suffolk County Police say Friday the 3 p.m. blaze forced the evacuation of the building. The Red Cross has relocated eight of them to a nearby hotel and 42 others have found shelter in a Salvation Army building.
Police say arson squad detectives are investigating what caused the afternoon blaze but don't suspect criminality. There were no injuries reported.
The fire came on one of the coldest nights in years, with temperatures dropping to single digits Friday night.
