Research On The Investigation And Evidence Collection Of Non-contact Crime Cases

The development of network and telecommunication services is constantly changing the way of production and life of the society,at the same time,it also has a profound impact on crime.Based on the network and telecommunication services,traditional crime is gradually breaking through the fixed space-time restrictions to "non-contact" crime.Non-contact crime cases are based on the means of network and telecommunications services,and achieve criminal purposes in the absence of contact between criminals and victims.Therefore,compared with the traditional contact crime cases,the crime cases have a stronger concealment.It has brought great difficulties to the investigation and evidence collection.This article attempts to grasp the concept and characteristics of non-contact crime cases,combining with the difficulties of current non-contact crime,and then proposes the way to crack the investigation and evidence collection of non-contact crime cases.This article takes the non-contact crime case as the research object.In addition to the introduction and conclusion,it is divided into three parts.The first part,first of all,from the theory of "de-region" in sociology and the theory of five elements of criminal case.The author thinks that the non-contact crime case refers to a series of criminal cases that the alienation of the various elements of the criminal case constitutes the separation of the criminal subject and the criminal object,and achieve criminal purpose through the criminals transmit the criminal intent through the network,telecommunications,etc.Then,based on the analysis of the concept of non-contact crime cases,it is concluded that the noncontact crime cases have the characteristics of concealment,mediation,intelligence and crossregional.The second part,author analyzes the difficulties in the investigation and evidence collection of non-contact crime cases from the aspects of non-contact crime case evidence,crime scene,investigation subject,investigation cooperation and so on.In the aspect of evidence,it is difficult to carry out the investigation and evidence collection work caused by the concealment,vulnerability and dispersion of electronic data.In the aspect of crime scene,the virtual scene and the cross-regional nature lead to difficulties in investigation and evidence collection;In the aspect of investigation subject,the professionalism of investigators is difficult to meet the requirements of investigation and evidence collection for non-contact criminal cases;in the aspect of investigation cooperation,the difficulty of cooperation in investigation is not conducive to the sharing of resources,the exchange of information and the handling cases in different places in the investigation of non-contact crime cases.The third part is the focus of the full text,it is mainly a perfect countermeasure for the investigation and evidence collection of non-contact crime cases.First,it is the improvement of the electronic data forensics system,which mainly includes regulating the evidence collection process of electronic data,establishing a mandatory data information protection system,and improving the data sharing mechanism;Secondly,it is the specification of virtual scene investigation and evidence collection,which mainly includes improving the evidence clue collection mechanism for non-contact crime cases and strengthening the legal regulation of virtual scene investigation and evidence collection;Then,the professional construction of the investigation team,the investigation of any case relies on the investigators.The quality of the investigation personnel directly determines the effectiveness of the investigation and evidence collection work.At the same time,the non-contact crime cases also require the investigators to establish big data thinking,make full use of all the data information to detect the case;Finally,non-contact crime cases have obvious cross-regional characteristics,and the resulting is that the investigation and evidence of non-contact crime cases rely on investigative cooperation,the improvement of investigative cooperation mainly depends on the progress of consciousness and material protection.The perfection of the mechanism and the support of the law.
