What evidence do public security organs need to collect in criminal proceedings?

The collection of evidence in criminal proceedings must be done by the public security law. The parties only provide evidence clues, and then they are investigated and executed by the Public Prosecution Law. The evidence provided by the parties shall not be recognized without investigation and verification. Of course, if you are a suspect, your defender will help you collect favorable evidence.

Evidence includes:

(1) Physical evidence;

(2) Documentary evidence;

(3) Testimony of witnesses;

(4) the victim's statement;

(5) confessions and excuses of criminal suspects and defendants;

(6) Appraisal opinions;

(7) Records of the inquest, inspection, appraisal, investigation and experiment;

(8) Audio-visual materials and electronic data.

The evidence must be verified before it can be used as the basis for finalizing the case.
