Well alright, i am a roleblocker. I'll check my PM again if you require specifics of the name, but i'm the captain of the ship. I blocked Steve Van Halen both nights, and there were consequentially no mafia kills. I thought we had the game won as a result of this, because if we'd kept him alive, we could have stopped the mafia doing anything for the rest of the game, whilst picking off the other suspects.
If the other kill was by a vigilante, then they should claim now, because that's a pro-town role and i'm fairly confident that there'll only be 3 mafia in a game of 12. If it's by a serial killer, than that person is somebody working alone to kill everyone off. I think the second is probably the more likely role.
But for there to have been no kills on night one, either that person got blocked, somebody got protected by a doctor, or they simply weren't around to get their night action in. So potentially, a townie knows who did the killing, and that would be pretty useful information to tell the rest of us. Effectively, it'd win us the game.
I'm very confident the mafia is Afroboy or Axeman, and like i've said, if someone also knows who the SK is, then that'd all but end the game.
