I think Tox was a detective who was aggressive towards Mona on the first night and, during the day, set up Rimpel to be targeted by the mafia. Again, why did he pretend to be a maniac... Maybe because the roles are somewhat similar.
Kitz was checked, she is not a mafia member.
In the game, it seems we have a doctor, a witness, a detective, two mafia members, and a maniac.

Барон "Vampires"
Отдай свои прошлые сны,
В сомненьях себя обрети,
В бешеном танце душа кружится!
Не думай, что будет потом,
Здесь и сейчас мы живем,
Стань хоть на миг сам собой, слышишь!
