Abstract:
Trace materials located at the scene of explosion are one of the most critical zones during investigations. Therefore, it is not a rare occasion that some of very important trace materials and facts found affect the end result of the case at the court in an essential way. For these reasons, with the development of scientific aspects of forensic sciences, more attention is to be given to the discovery and preservation of the integrity of the evidence which are to be studied later by the subject matter experts in the criminalistic laboratories. One of the most mistaken approaches to this issue, which is related with the modern apprehension of the forensic science, is that this field is sometimes tied with the work of criminal laboratory’s technicians only, which in reality presents a major mistake. It is a fact that the skills of a laboratory technician to provide justifications on scientific basis are largely dependent from the observation, collection and evidence recording at the scene of a criminal event, because the criminalists located at the scene is to the same extent part of the forensic science, also as experts in the laboratory. If trace materials are not managed properly, the work of the criminalistic laboratory can be questioned to a great extent. This is one more reason that requires attention, both at the scene and at the entire routing until the trace material obtains a judiciary epilogue.
