The Judge

The Judge is a former policeman who also happened to be Busset's mentor. His motivation for the series of killing is to punish criminals who did bad things like rape, murder, and the liars who slipped away from the justice system. His weapon is a well-maintained pistol manufactured in the 70s. The player can accuse him after talking and collecting important clues from a gunshop owner, thus leading to the events that leads to the Judge's suicide. There is a way to keep the judge alive, but I am unwary of where to look.
