It's very late and I'll go to bed. I'll make my final analysis for the day....
All we have so far is Zach being whacked. The only question we can ask ourselves is why was Zach whacked? It's not your usual strong player whack, so here we at least have something to go by.
There are 4-5 possible answers imo. Personally, I exclude a plot made by the so called stronger players. I know most of you and I know that neither of Hoori and Osman would have whacked Zach on day 1 as part of some plot.
What we're left with is:
a) Plot made by other players, as some kind of mind fuck. You see, an average chess player sometimes makes a move which seems brilliant to him, just so the better player will beat him exactly because of that seemingly brilliant move. If this is what happened, then look at Voller and Matt ahead of everyone else.
b) Something personal. Someone who dislikes Zach and had no doubt who to choose when the whacking time came. In this scenario, it's Preet. But this doesn't exclude a stronger mafia player in their group. If there is, he/she wasn't online at the time. So, me, Hoori and Deneb. In any case, if this is the scenario, then we have to look at Preet for now.
c) Zach attacked or voted for someone and the "someone" is not an experienced player who'd ignore Zach's votes. Tomice and Voller were the ones he attacked, right? Not Tomice, but Voller would whack Zach for this.
d) PM stuff. Someone PMd Zach and with his answers Zacheryah left an impression of a special role. But who'd PM Zach? I'd do it. Osman would do it too. I was offline all day. Osman was here.
I also exclude a shot in the dark, hunting for the detective without any hunches. The Gs don't hunt for the detective if they don't suspect anyone for being a special role. In such a case they shoot me, Osman, Hoori.
You can choose one of a, b, c and d. I choose B.
