There are two ways,
1 by entrusting your own lawyer or going to the public security and judicial organs in person to inquire about the progress of the case.
But in this case, it is not easy to find out the real progress, because the judicial organs have discipline in solving cases, and some cases need to be kept secret. In the stage of detection and investigation, some information of the case cannot be known by the people involved.
The second method is to entrust your friends or family members who work in the judiciary to inquire about the task force.
In this case, the progress of the case is relatively guaranteed.
Finally, if you are the victim of the case, you can send some worthless things such as mineral water and masks to the task force in the name of condolences, express your condolences to the judicial personnel of the task force, and check by the way.
thank you
