Well, I've looked over what I know, read everything in the thread now, and I still have 2 mayor suspects.

Boko: He's been behaving exactly like he always does when he's scum, which concludes yet another mafia game where he is mafia. I'm not ready to make a case against him, but I will start gathering evidence.

Qwerty: No useful information, does ask others a lot, but still hasn't recovered from the extremely scummy behavior in the first day. I believe he was meant to be a sacrifice for the other mafia members in the original plan.

I'd like to hear Del's opinions please.
