Why would you care what Sallu was? When you first revealed the investigation result here, it was already suspicious.
1) Sallu was meant to be identified by Juliet not you.
2) This doesn't add any credibility to Juliet's claim.
What could have been possible here is one of two things:
1) You knew what Sallu was cause you killed me which means your mafia, which if Fuji flips scum, we'd know that you're mafia for protecting him.
2) You got lucky with the Sallu investigation result.
I'm unlikely to believe number 1 cause of my town read of Fuji, which leaves me with number 2. Unless you know, you as mafia came to protect town Fuji, but this is a metagaming perspective built on possibility which can only be confirmed by Fuji's flip and I'm not lynching Fuji cause of my read. So you're scum to me.
