Crime scene management is the first and most sensitive stage in criminal investigations. Given the role of material evidence existing at the scene for substantiating the occurrence of crime and identifying the criminal or establishing the innocence of people charged, it is highly important to maintain and investigate crime scene and to gather crime evidence existing at it. This research seeks to identify components and indices of optimal crime scene management. This research is an applied one in a descriptive- analytical form. To analyze data, single sample Wilcoxon's Test and to rate, Friedman Test were used. The intended statistical population consisted of judges and experts of crime scene investigation in the city of Tehran for the as many as 50 people. Research findings showed that optimal crime scene management components and indices were determined by using the views of experts and investigation sources, and research findings confirmed the effects of these components with the priority of "identification", "other major factors", "reconstruction", "specificity", and "sample determination" in optimally managing a crime scene. Therefore, research results showed the extent to which each of the components and major indices affected the optimal crime scene management. The most important applied recommendation of the research was concerned with the establishment of an effective coordination among actors engaged in investigating the crime scene.خلاصه ماشینی:
"The statistical hypothesis at the confidence level of 95% is defined as follows: Null hypothesis: Component reconstruction is not effective on the optimal crime scene management Alternative hypothesis: Component reconstruction is effective on the optimal crime scene management Results from the single sample Wilcoxon's test are provided in Table 12 Results in Table 12 show that the significance level of all items pertaining to this hypothesis is less than 0. The indices for each of these components are summarily elaborated on in the following: Research findings confirmed the effects of all four main components and the sole component of "other factors" in managing the crime scene optimally, and beside these components, the component "other factors" thought to be effective in managing crime scenes optimally was placed in the second rate in an overall rating after component "identification", indices of which based on the priority of effects are: Full protection of the crime scene before the crime scene investigators arrive; Necessary actions by the first police patrol officer entering the crime scene; Timely presence of the inspector at crime scenes for managing the crime scenes; Provision of universal training to citizens in respect of crime scene protection methods; Establishment of previous coordination with regards to duties and the actions of various actors present at the crime scene (Police, judicial officials, forensic medics, rescue workers, etc. 5. Recommendations According to the research findings and the much effects of major components and indices on optimally managing crime scenes in Iran, the applied recommendations are provided as follows: - Crime scene and identification experts are recommended to take into account fourfold indices and components, including identification, reconstruction, sample specificity and sample determination, corresponding to the findings, in their own special measures quite comprehensively."
