If Daniel isn't inspector, it's certainly jfrisch or Alex, and probably jfrisch. First, he's just been acting like it, and second, a lot bigger deal was made of him being a "confirmed" innocent (which, TBH, having seen him as Mafia, he is) than has been in the past.
Personally, I think it's unlikely that dgrazian's the inspector, because I don't think he's enough of a "wine in front of me" type person to claim on his own behalf, and because I think jfrisch is his inspector. That said, I could be wrong. But I think we should definitely kill dgrazian next, and definitely with a hitman. If he's ironheart or lynched, jfrisch should be the next target. He's usually in Random, on Pecker, Clam, or Bonfire.
Incidentally, both of them hang out on Bonfire with some regularity. If you're going to kill them on Bonfire, please make sure I have a decent alibi, because I'd prefer not to be obviously Mafia. Note that this isn't hard, it just requires that the kill not be made in the late evening. If anyone wants to coordinate with me on this, email or text is best,

I don't see why delaying kills helps us against the mad scientist. We should kill dgrazian ASAP, and go from there.
