yeah, I checked Canada’s Missing/RCMP and a couple other databases and there don’t appear to be any developments since the case listing , no recovered boat, no found remains and no arrest. Lake Superior around Caribou Island is cold, deep and has strong currents, so a small boat can sink or be carried under without ever washing up, which would explain the complete lack of surface wreckage. If anyone from the Shuniah area still has memory of that day, even small details about boat type or time of day could matter, since this looks like a presumed drowning with no new leads.
