Mondo as the killer makes sense, though then the issue of him knowing about the crucifixions comes into play. I'm still leaning toward Togami, though not nearly as much as I was earlier. I suppose it could be fortune teller dude who's been playing really dumb this whole time. And despite how nonsensical it would be, I feel like Asahina was acting extremely suspicious this update.
