In a criminal case, my father was interrupted by three ribs for salary, and the examination time was a few days late, saying that there was no causal relationship. What should I do?

First, you can continue to investigate and deal with the relevant departments through letters and visits or complaints;

Second, even if it does not constitute a crime, it should be punished according to the situation at that time and given public security detention. If it has not been punished, it may require public security punishment;

Third, for the part of damages, you can claim compensation according to the relevant evidence and expense documents at that time.

It is recommended to ask a local lawyer for help. In the final analysis, what should be won is still to be won, and there is no way to win it.
