What do you mean the case is under further investigation?

Investigation is an offensive measure that criminal investigation departments often take in the fight against criminal offences. The meaning of investigation means that the case is still in the process of criminal investigation, and the case is in the stage of investigation and evidence collection by the investigation organ. Whether a criminal suspect constitutes a crime and what charges he may constitute should be judged according to the investigation results.
