In this paper, we tried to study and explain the concept of digital traces in crime scenes. First, concepts such as Metadata, physical effects and physical and digital arguments are explained, and then the extent to which the effects of digital imprints on criminalizing referrals are judged by experts is measured. The purpose of these digital effects is the activities of individuals who remain in telecommunication networks, CCTV cameras and cyberspace. This "effect" of the various people and their vehicles in CCTV cameras, as well as FRT camera cameras can be followed. In this research, the intention is to produce theoretical literature for detective guides on telecommunication data and familiarity with the related facilities. Considering the importance of the subject and priority of NAJA in relation to the scientific discovery of crimes, using the researcher-made questionnaire, the impact of the dimensions of the independent variable of the research is measured from the viewpoint of experts to 40 people. One-sample t-test was used to compare the mean's and to prove or reject the hypotheses. Friedman's analysis of variance analysis was used to prioritize the indicators and dimensions of the variables. The result of the test of research hypotheses shows that the digital telecommunication effects left on the crime scene and offender activities are greatly effective in criminalizing and identifying offenders and has obtained the highest priority for the statistical community. The priority order is for telecommunication experts, the visual dimension, and the effect of criminals' activity in cyberspace.
