The restoration of the whole case has always been from the lawyer's point of view. Finally, after he was released from prison, he admitted in disguise that the stationmaster did kill him. However, due to the principle of non-repeated prosecution, he cannot be investigated for criminal responsibility.
The old criminal police also indirectly admitted to extorting confessions by torture in order to maintain their performance. Therefore, according to the rule that extorting a confession by torture should be excluded, this guilty confession is not the basis for conviction. Therefore, the guilty confession of liquidation cannot be used as the basis for conviction in this case.
