There's no word of any arrests or information that might break the case open.
Instead, the OPP made another appeal to the public on Thursday for help solving an historic murder case in the Muskoka region.
Four seniors who were living in retirement homes run by the same family vanished in the late 1990's.
Authorities say the family behind the businesses has never co-operated with the investigation.
Some members of that family are described as 'persons of interest' by the OPP.
Provincial police are calling for new witnesses to come forward.
