OOC: Blame these are good observations. I believe the two primary reasons for kills are:
Metagaming: "What roles are important?". This was clearly the case with Choxorn, and probably Stee too. Backwards Logic
could also fall under this category.
Former experience: This is most likely what happened to BL and Renata. Someone among the wolves are afraid of the experienced players and/or players which they usually talk to and who would suspect them sooner or later. I think this is plausible to use as BL's death cause (just look at his signature

)
Combining the cynicism that it takes to kill someone you know and play with this early (especially Renata's case was bastardly) and the metagamish line with someone who knows/plays with Renata and BL, we get these likely wolves:
1st Private (Female): Diamondeye
3rd Private (Female): Nictel
Cook (Male): askthepizzaguy
Government Representative (Male): TheForestAuro
Janitor (Male): civplayah
Rifleman (Male): Winston Hughes
Second In Command (Male): Methos
Security Officer (Male): Catharsis
Sharpshooter (Male): rhawn
This is a list constructed with an attempt at impartiality.
We can strike out Methos as he has been inactive until now. That leaves eight prime suspects (of which I am one).
From my judgement thus far, I would find it unlikely that the following persons on that list are guilty: Diamondeye, Nictel (Not sure), Catharsis.
I have some sort of trust in: AskThePizzaGuy (Not sure), TheForestAuro.
I strongly suspect to find a wolf among: Civplayah, rhawn, Winston Hughes.
I hope people follow this reasoning and keep the nine people on the list and especially those three listed just above in mind.
