Well, I'm going to go ahead and get my vote in now. I imagine the Sheriff is either having trust issues, or hasn't nailed a Mafia at all. Perhaps they died, who knows..?
I had heavy suspicions on King Heffy early on, still very suspicious of him at this point and time. Caboose as well,
Vote King Heffy
Sorry bro, you're my Peaches, and I'm your G_Bassi
