Well if its suppose to be unexpected, then i'd say either Chris or Alison Argent, since both Derek and Peter killed a close member of they're family.

But they can't really blame them, since they had good reason, Kate was crazy and deserved it, and Victoria killed herself after Derek bit her in self defense.
