Who killed the head of the slang lawyer?

The director of the slang lawyer may be the boss of the rat organization. There are five specific guesses:

First, the head of the room is the person around the hero, who has mastered all the dynamics of the hero and bought a fierce knife for the VIP. ?

Second, the housemaster can play tarot cards. In the early stage, the housemaster taught the male master to solve tarot cards. At the beginning of the TV series, the supervisor's fortune-telling story suggested that the supervisor was from the perspective of God. ?

Thirdly, in the tenth episode, the warden said that the paper had something to do with the death of a very important person-a mouse. The warden once asked that person to help him find his daughter. ?

Fourth, the warden looks like an ordinary old man, but he is classified as a "senior" prisoner by the warden. It's not his turn to dig out dung, and he can play chess with the warden in the office, suggesting that everyone in the prison is their pawn. In the episode 10, he even went in and out of various places in the prison and did odd jobs. ?

Fifth, the man showed the woman who was most afraid of the big mouse when the warden was arrested, and at this time the camera swept the warden's frown.
