Will the public security bureau be held accountable for Ou Jinzhong's case?

Ou's suicide belongs to the death of the suspect. What is certain is that with his death, he will not be investigated for criminal responsibility. Before he committed suicide, the case was in the investigation stage of the public security organ, so the case will be dismissed and the investigation will be terminated.

No one shall be found guilty without a judgment of the people's court according to law. In other words, Ou is not a criminal, but a suspect. Even if the whole village witnessed his killing process, witness testimony is enough. Before the hammer of the court fell, he was not a criminal but a suspect. This is a judicial requirement.
