Tanmoy Kumar Mukherjee, Annwesha Mazumdar

Abstract: A comprehensive examination of crime scenes and a detailed forensic analysis glass pane penetration provided significant insights into an alleged bullet-firing incident. This report employs forensic techniques, including laser ray projection and gunshot residue analysis, to determine the true nature of the incident. No evidence of projectile penetration was found. The glass pane exhibited radial and concentric cracks, along with ridges and Wallner lines. A pink curtain in front of the window remained unblemished, indicating that no projectile penetrated. The investigation meticulously ruled out the possibility of external projectile penetration, underscoring the importance of internal factors in this case. Additionally, the absence of any gunshot residue at the scene further supported the findings, reinforcing the need for detailed forensic work in crime scene investigations. These findings underscore the importance of meticulous forensic investigations in crime scene analysis and emphasize the necessity of precision in forensic fractography for resolving complex cases. The investigation revealed the absence of projectile penetration and an unblemished curtain, casting doubt on the initial claims. The analysis concluded that the glass pane was broken from within using a blunt instrument. This case underscores the importance of detailed forensic work in determining the truth behind crime scene evidence.
