In a case that has confounded investigators and creeped out Canadian beachgoers, at least six severed human feet have been found on the shores of British Columbia since August 2007. The most recent discovery was in November, when a New Balance athletic shoe with a human foot inside was found south of Vancouver near the mouth of a river. (A black high-top sneaker with a foot inside was found on the beach in Washington in August.) One of the feet found in Canada was identified as that of a man who had been missing for months; two others have been linked to a different individual, still unidentified. Medical experts say that the feet most likely detached naturally from bodies floating in the ocean, but why so many have found their way to the strait between mainland British Columbia and Vancouver Island is still unknown.
