The Reappear Of Investigation Research Theory

At present, in the research field of investigation, the research directions of it is mostly in the procedures of investigation, the measures of investigation and the mechanisms of investigation seldom refer to the reappear of investigation research. Even if it has a research, it is just limited to the concept and content, is lack of systematic senses. In fact, the reappear of investigation is becoming the main field of specialists in some countries. The reason is that reappear of investigation is completely reconstruct the crime scene by study those material evidence and marks systematic. So, the paper is just to upgrade the reappear of investigation from the evidence.Firstly, the paper is hold the methodology of reappear by analyze"three theories", the information theory, the systematic theory, the control theory. The crime information is not only the foundation and medium of reappear, but also the premise of the decision of investigation. The all reappear of investigation is encircle to collect the information or evidence. The investigation is a systematic of collecting, dealing and handling the information. And the crime is a systematic work which is adjusted by the crime actor. And more, the reappear of investigation is also a act of control. The investigation is full of the conflict of control and anti-control. Fight with each other is just to uncover the crime. So, it has the meaning of theory and practice to applying the information theory, the systematic theory, the control theory.Following, with the system of evidence theory, the paper analyze the relationship between the evidence and investigation. It is important for the stage of investigation. The proof is the whole core of litigation procedure, regardless of the stage of investigation, the inspect, the judgment. To the workers of these units, if they want to prove the truth of a crime, they must gather proofs. The proof is to prove the fact of a crime. The investigators want to reconstruct the crime scene, they should rely on evidence. The paper is start from the marks and material evidence to reconstruct the crime scene. For the marks and material evidence is the most important to reappear of investigation.Immediately after, because of the crime gradually becoming more wisdom and form, the traditional investigation model is not very well, we should upgrade new method and means of investigation. We have to improve our measures and means of investigation. The crime psychological trace becoming more and more important to reconstruct the crime scene. So the writer analyze the meaning of the crime psychological trace to reappear of investigation research.Finally, according to the fact that reappear a crime scene would face so much problems and shortages, the writer try to set up a more excellent mode of investigation reappear, the key point is that we should collect proof more careful, and analyze the crime mind trace more objective, and evaluate the standard of emersion should objective reasonable.
