Pretty sure are town:
Ecto, because he has a correct investigation on me.
Twito, because Ecto has an innocent on him. Godfathers are a consideration, but it seems unlikely that he'd claim a power (like roleblocking or boosting) that is testable if he has no way to demonstrate it. Only way I could see him being scum is if he's a Godfather of the group that has a roleblocker in it (the one blocking cops is definately scum), and that seems a pretty iffy theory- as Thok pointed out, there was no reason for scum to block RR if they knew he was targeting their investigation immune godfather that night.
Likely town:
IH and Zindaras, because it'd be risky to claim masons when the death of either would incriminate the other. Alignments aren't guaranteed, so it's possible that the mason claim is true and one isn't town.
Uncertain:
Thok and Fritzler. Fritz has stated that Thok is town but has ignored questions as to why; I'd really like him to state whether he knows for certain, and how, so he can't just write it off as being based on gut if Thok dies and ends up being scum. Thok, for his part, said he thinks the claim of Thok being town was a reasonable followup to Fritz's variable win condition claim, which I don't really understand. The connection is something we may want to look into.
I don't really have anything solid on DoS, HH, or Nightfall. I'd like to change that.
I'm going to have to do a reread so I can base some of this on gameplay and not just claims, but that's probably going to have to wait til the weekend.
I'd been operating under the assumption that there was a 4-5 person mafia and an SK or vig, but the lack of a readily apparent connection between the two dead scums' roles may indeed be an indication of two mafias.
