Arandora was killed by Ant. He had a pistol without a silencer and a garrote.

Notably, there are fingerprints of small, most likely female, hands on one of the wine bottles in the minibar, and ash from a cigar remains on the threshold.

This is a clue pointing to the killer.

Weapon: AK-47

Is this a more impressive weapon? Ar - Bezim? Or does a couple more players have Uzi's?

There was obvious surveillance on Verwolke. Vistris was recruited.

Therefore: recruitment by the mafia, murder by Ant, and someone from the city's Neiru was involved.

The Albanian mafia is involved in the trade of white slaves, alcohol, and tobacco.

Only Bezim was involved in tobacco. Or is tobacco an indication of the killer's or the victim's role?
I'll think about Neiru's murder for now.

And Carlito was apparently monitoring (checking the status) of Torii. And Torii is neither Papa nor Grim.
Or Demi was checking the status, and Torii could be either one.

Is Santiago's block on the side of the mafia or the city?

But Carlos is larger and smells bad, so Torii is probably not Papa or Grim. Or maybe the 50% chance didn't work out.

And Demi was hanging out with Ara and checking on him.

Or Grim was recruiting. But then how was Vis recruited?

How many influence points does the mafia have per night?
