Why? There's a lack of evidence; almost nothing was found. This benefits the Mafia, and you just stuck to general statements.
Just like Ar, who simply recopied the analyses that were done before him.
And I'm going with NNV because I can't say anything concrete in this way, for example: that he killed Neira because there's this piece of evidence against him.
You yourself said that you didn't find any leads.
Message #192 I didn't find any real leads on the monster.
NNV
So, if the Mafia votes for NNV, you're one of the Mafia, just because you suggested NNV.
