Abstract

Abstract:

Introduction- The fingerprint is the most useful form of evidence that can be found at the crime scene. It helps in establishing the identity of the criminal. Criminals nowadays are quite aware of the importance of the significance of fingerprints found in the crime scene, therefore they make all possible efforts to erase the prints from the scene. Despite such efforts, chance prints are often left behind in the scene. Chance prints mostly are latent and require thorough development procedures to use for convictions. Several well-known methods of development already exist in the literature but are not very cost-effective. 

Materials and Methods- This study explores unconventional methods for developing latent prints, investigating their effectiveness using various substances and considering environmental factors. The different powders used for this study were Banana Powder, Asafetida Powder, fenugreek powder, Milk Powder, Beetroot Powder and Neem Powder. All powders were tried on both porous and non-porous surfaces to assess the results.

Result and Conclusion- The research’s implications are significant for forensic science, aiding in perpetrator identification, exoneration of suspects, and DNA evidence preservation. The study concludes that Banana powder and Beetroot powder are effective in developing prints on porous surfaces.
