Specific SPN/Criminal Minds crossover case!fic

[jadehunter]

I tried googling, ff.net and Ao3, and found several other great SPN/CM crossovers but not the specific one I'm looking for. It's a gen case!fic, where both teams end up looking for the same killer and I only remember this one specific sequence: Dean and one of the BAU team are locked in a cellar where the bones of all the killer's victims are, while the killer is (I think) hunting JJ in the forest. The killer is human, but Dean provokes the bones of the victims and gets them to manifest as vengeful ghosts who go after the guy who killed them, which buys them all enough time to get saved.

Edit: Found! Link in comments.
