My thoughts:

Either both Yaro and Csargo have both died, and are either characters who will come back later in the game, or are characters who can't actually die (the role itself if you know what I mean, they are out of the game but the 'role' isn't killed) Certainly the fact that Yaro is voting is interesting.

Monty is always talkative generally Chaotix.

Regardless, 3 kills a night is not so unusual. A special power that can kill certain things, etc activating, + plus mafia and sk or vig kill, or even any combination of those. There are probably other ways for them to die too.

A one man mafia team is a serial killer. If we need to find the pure sacrifice, then it is bound to be a serial killer, one of many maybe?

Either way, Vote: Chaotix seems find to me.
