Decipherment of latent fingerprints are one of the most common tasks in crime scene investigation asit carries the unique identification feature of the individuals related to that offence. Powder dusting isthe most suitable method to develop latent prints on a wide range of nonporous and semiporoussurfaces. In present work, a commercially available talcum powder, generally used as a commoncosmetic product, has been used to decipher latent prints on 28 non-porous and semi-porous surfacescommonly encountered in daily life. The powder is economic and harmless in nature and easily availablein market. The results showed that the powder developed good quality fingerprints on most of thesurfaces and can be a good substitute of conventional powders.
