Non-Public Case Record Book

All kinds of cases happen every day in this world. Normally, many cases will be handled properly. However, there are also many unsolved cases, the murderer cannot be identified, the deceased cannot be identified, the motive cannot be confirmed, etc. In addition, there are also cases where the identity of the murderer cannot be identified. These cases will be handed over to the non-public department for processing, that is, non-public cases. Well, anyway, that's what I do now.
