It is necessary to collect evidence according to the characteristics of the evidence in intentional injury cases, and focus on ascertaining the basic facts of the case, that is, who is the person, for what purpose, what means are used, how to injure others and the result of the injury. When collecting and fixing verbal evidence, attention should be paid to legal procedures, and attention should be paid to repeated questioning (interrogation) from different angles on the same fact to produce transcripts. Be good at using modern scientific and technological means to collect and fix evidence. For evidence that is difficult to collect or fix using ordinary methods in practice, rely on modern scientific and technological means to collect and fix evidence. 3. Strengthen the review and judgment of evidence. Persist in comprehensive review of evidence, especially review of key evidence, and strive to ensure that the evidence in individual cases is reliable and sufficient. During the review process, whether we start with the subjective and objective elements constituting the crime of intentional injury, or look at the sequence of the incident, we cannot ignore the objective connection between the evidence; from the victim's statement, the criminal suspect's confession and defense, and the witness In terms of testimony, from the diagnosis certificate issued by the hospital, the criminal technical appraisal’s explanation of the time of the crime, as well as the relevant criminal technical documents and on-site investigation and inspection records, we can grasp the precise time and place of the crime, find the precise criminal subject, and analyze the case Facts, fixed crime tools, and screening medical appraisals make the evidence of the entire intentional injury case form an objective and true chain. In order to prove whether the crime of intentional injury was committed by the criminal suspect, we should focus on reviewing and analyzing the victim's statement and identification transcripts, witness testimony and identification transcripts, the confessions of the criminal suspect and his accomplices, the time when the criminal suspect committed the crime and the time of the crime. Evidence of motive and purpose, necessary fingerprints, footprints, blood stain identification, etc. 4. Strengthen the guidance and supervision of investigation activities and improve relevant mechanisms. The procuratorial organs should increase their guidance on investigation activities. When necessary, in the detection of some major cases, the procuratorial organs can intervene in accordance with the law to ensure that the investigative organs collect relevant evidence in a timely and accurate manner. The public security and procuratorial organs should strengthen communication and coordination, jointly develop and issue evidence standards for public prosecutions in intentional injury cases, and break down and refine the standards for collecting and reviewing evidence. The corresponding responsibilities of investigators should be stipulated in the quantitative assessment system of investigative agencies, and the mentality of "emphasizing solving cases and neglecting evidence" should be reversed from the institutional perspective.
