Technically it could be Drafter, if so I concede the game to him.
No heat has been on Oro, so he could be hedging his bets that all the more likely people will be eliminated leaving just him and drafter, and thus making him still win. I think it was yesterday he said he had been sabotaged, which I am not sure if people would get a notice about it (nor am I sure anyone would mention it, much like Speed, Drafter, and I have not mentioned the now pointless notifications of where the mechanic and vest have gone).
Duhhamburglar is new AFAIK, so anything is possible. I'm honestly surprised you have not tried to lynch him for him repeatedly using autistic as an insult.
There's also me, who if mafia would guarantee the game was completely unbalanced.
