Through the study of this topic paper my aim is to explore the problematics of the proving process for the homicide offenses in Gjilan after 1999. This paper reflects the detailed theoretical and interpretative approach of proving process based on legislation which has been implemented and the actual criminal procedure in Kosovo, based on the Constitution and the European Convention on Human Rights. In principle, all the activity of proving process refers receipt, reviewing and assessment of the evidence as sources of acknowledgment through which the court, by proving the relevant facts of the criminal case, decides on the benefits of the individual such as freedom, honor, wealth. The process of proving has as the object, all posts associated with elements of criminal offense, the social relations that have been violated/encroached, time, place, method performance, circumstances, consequences and casual connection with it, the author, cooperation, danger, guilt and the form of guilt, motives and purpose in doing it and everything related and in the interest of resolving a case. Throughout my work in this paper based on the statistics issued by police and prosecutors, I will attempt to find and present/introduce some of the general and specific characteristics, which have been obstacles for the process of proving and institutions of investigation in the municipality Gjilan for the period from 1999 to 2014 were confronted. The purpose of this paper is to give assistance not only to understand the role and great power the proving process has in relation to the evidence in the fight against crime, but also to better identify the problems through which proving process passed, depending on the conditions and circumstances in which an offense of murder happened/was committed . The importance of the paper is shows up/emerges seeing the growing attention being devoted to the problem of proving process through the development of relevant legislation, professionalism of staff and modern technical and technological equipment . The criminal procedure law represents the joint object of study/research of the right of criminal procedure and criminalistics, so tracking and detection of criminal offenses today is unimaginable without the help of forensics (Traseology, dactyloscopy, forensic photography, etc), as well tactical and forensic/criminalistics methodology.
