Mafia 40. In the Name of the Emperor

Well, here we go again with the arguments and accusations. Anyway, here's my approximate list of suspected Mafia members, in order of decreasing certainty: Mold, Lizard, Lord, Cat, Amko/Jack. I've more or less formed an opinion about the rest (excluding the inactive Delirious, where I might be wrong). Of the last two, either one is Mafia, or both are – I can't determine their roles yet. On the one hand, he described having a pistol, meaning he could be a Commissioner/Iterator/Psyker; on the other hand, he was shooting, so it could also be a description of a K.O. (even though he doesn't have a rocket launcher now, but nothing clearly fits any role). Plus, as a wild guess, we could consider a Techmarine with his good training, protection, and rearmament (meaning he could have any weapon, not just a pistol).
I'm leaving now; maybe I'll check in later tonight or tomorrow from my phone, but I probably won't change my vote.
