Background: Gunshot residues are collected after shooting incident or firearms used, using to determine the composition of the GSR reference by various techniques to choose methods and techniques most suitable for this type of analysis, such as SEM-EDX, NAA, LBIS and etc.

Objectives: Our proposed study is to determine the elemental analysis of GSR using EDX – 8000 set-up. All the GSR constituents lead-barium-antimony (Pb-Ba-Sb) are verified in the Indian made ammunition.

Methods: Samples of metallic powder residue were realized after several shoots by different kind of weapons (country made firearms) with local ammunitions. So, this study was undertaken to develop chemical ballistic specialty in order to improve forensic investigations and drive benefit to Indian police and forensic experts.

Results: Our results reveals that the non-destructive - EDX method is quite adequate to analysis the proposed investigation.

The rape crime-clock is very alarming compared to other crime against women in India. It is seen that different age groups including kids are the victim of such menace. In one case, a 6½-year kid used to visit the neighbouring house to play with her girl friend of same age. One day, the uncle (father of her friend) lured her and took her to a nearby bushy area close to the house. The kid was raped there and strangulated with a flexible wild creeper (rope like plant material) and abandoned naked on the spot. In the mean-time, parents of the victim girl enquired the place where she often used to visit and play. Since several hours passed without any result, an FIR was lodged in the local police station. Subsequently in the late evening, the detection of a dead body (kid) was reported and identified to be the same missing kid. As per secret input, it was ascertained that the deceased (kid) was last seen with the accused moving towards the bushy area in mid hour of the day. The undisturbed crime spot was examined by the police and forensic team to collect physical evidence and establish the crime and criminal. The autopsy findings and criminal psychology along with other details have been discussed in this paper.
