Since 2007, 16 severed human feet, still in their shoes, have washed up on the shores of the Pacific Northwest. There have been some men, some women, and various ages and sizes. The facts can get more specific than that if you want them to (five men, one woman, three New Balances, two Nikes), but it doesn’t change the fact that, that’s effectively all we know.
Earlier this week, on Vancouver Island, foot number 16 was found. This time, it was a running shoe, a black sock, and a person that likely disappeared sometime between March and December 2013. Once again, the remaining facts — the little that there are — won’t do much of anything to answer your question: why?
