Summary/Abstract: In this article are continued the experiments carried out in order to achieve more information regarding the persistency and abundance of GSR particles found in the head area of the human body. The results obtained in the first study were really surprising and had a major impact in our expertise area, confirming the theories about the fact that GSR particles are still detectable after a longer period of time in areas very exposed, but mistakenly unexplored during crime scene investigation, due to lack of attention or knowledge, most of the times. These unexploited areas offer valuable information in most cases where relevant results are missing. Same conditions of analysis were applied in order to have a better reproducibility of the data obtained, detection and characterization of the GSR particles were performed with SEM/EDS analysis, where elemental composition, surface morphology, particle size and particle population were taken into consideration. This new set of experiments was carried out on more types of ammunition and the results surprised us once more.
