Just in time for Halloween, there's another twist to the disembodied feet mystery. But this is no ghosts and goblins mystery. Theories of serial killers, plane crashes and tsunami victims have been suggested.

Just this past Tuesday 10/27, another sneaker was discovered washed ashore in British Columbia. Not familiar with the case?

In late 2007, a 12-year-old girl found something unusual along the shores of an island in British Columbia: a male right foot inside a shoe that had washed up with the tide. Six days later, another foot in a sneaker had washed up, this time forty miles south. It was not the missing half of the pair however, but a different right foot. Over the next fifteen months, four more feet washed ashore in the region.

Now another sneaker has been found. Though it has not been confirmed it's related to the others, it does add another clue to this bizarre mystery.
