Just got home and reread everything. First of all, I find this game much harder to figure out than the last one, where I was pretty sure that Tomice and ALC were Gs (and Preet too). Anyways, here are my thoughts:
The three most suspicious posters to me so far are Fred, Osman and Salvo.
Fred, who I already suspected a bit yesterday did himself no favors today, and particularly strange is that his only argument through the past two pages seems to amount to "I'm a C, believe me". His vote on Fr3sh does not look good at all, and I'm not sure if I buy his explanation that he had to leave due to his job. While that might of course be entirely possible (though weird considering he lives in the middle east(?) and has to leave for work at ~21:00 PM), if it was true, he could and should have said that before he left. He was already under pressure, and should have recognised that if he left without any prior announcement, it would make him look even more suspicious.
Taken one by one, all these little things don't really mean that much, but if they all come together on one person like this they contribute to a rather unfavourable picture.
Osman's case I admittedly can argue only in a bit less concrete terms. First of all, he seemed extremely aggressive towards Fred on the first day, although I do not recall him having acted suspicious in any way prior to that. Then there was his fit due to the clusterfr3sh, although I have seen Osman getting similarly emotional due to comparable things. Another thing was his reaction to the whacking of radekas', where to me he seemed a lot less intelligent than he really is, almost like he faked being clueless. I have to say as I am typing this out that my argumentation concerning Osman is not that convincing, but I get a lot more G vibes from him than other players. There are also quite a number of people coming out to defend him, with X leading the way. I guess that could be said about Fred as well though.
Finally, Salvo. He has acted rather strange the throughout the whole game, the pinnacle of which was probably his voting activity before the deadline. What here speaks in his favour is probably that it would be pretty stupid for a G to draw attention to himself like that, rather needlessly it seems. But even other than that, there was his weird reaction to the Fr3sh case, where someone (?) already pointed out that he acted as if he deliberately wanted to stay out of it, just to avoid any attention whatsoever. Adding to that is his later "obliviousness" of the post where Fr3sh posted his password. Besides, while I don't exactly find Fred trustworthy, he may have a point with him displaying a similar posting behaviour when he was a G last time, though I'd proabably need someone else to confirm that.
With that in mind my final vote will probably be Fred or Salvo. Between the two, Salvo seems the slightly more likely G to me, however I feel as if Fred's death might give us more answers in regards to Klin and Osman, his arguably two most vocal critics. Of course one can question the usefulness of these answers, as it could just as easily be a long game by the Gs, I think Maddy suggested that already.
Please call me out on any mistakes I have made or things I have missed, I only relatively briefly read through today's preceedings, might easily made have an error.
A post of my thoughts on other players is coming up shortly, but this one is long enough as it is already.

I forgot to add, I'm ~80% sure that at least one of Fred and Osman is a G.
