Well, in the frame we have Kira, Darkie, Zenigame, Aamto, Obi and Sanjay. Due to the fact we have no clues, I guess those who will try and defend themselves will be a suspect. Also by knowing that Obi is Percy and would most likely know who fudge is, and Obi stands to take over if Fudge dies. So either way Obi is in quite the predictament with the ministry if anything and will most likely be a target.
As for Kira he was too quickly to jump on the bandwagon, this may he suggests he has something to hide, as did Zenigame, without any reason or logic he voted Obi giving him some thought that he might be the mafia, however with Kira being so open to inspection gives some doubts.
Aamto is in the frame due to Obi, and as Obi said by not fully believing in his 4 guidelines that would make Aamto a liar, however I believe that Aamto was likely to be sarcastic, however this should make him a potential target for one of the mafia's if he is indeed allied with them.
Darkie and Sanjay were both quick to protest their innocence and with this they will likely to be up for discussion or investigation.
So, what we have is a 6-way frame, with Obi leading the most votes out, I wonder how this one will pan out.
EDIT: Since I am unsure, I will reserve my vote to later
