<![CDATA[The practice of using small partial reagent (SPR) for the visual development of latent fingerprints is the preferred choice, particularly concerning wet surfaces. In the present study, non-porous surfaces impinged with latent prints submerged in the water simulating acidic basic and salty water bodies were developed with activated charcoal based small particle reagent method. As evident from the observations, the activated charcoal-based SPR method was able to develop latent fingerprint submerged on the glass surface for up to 11 days and on aluminium substrate, up to 12 days but the quality of fingerprint observed was better on the glass substrate. The shelf life of the activated charcoal-based SPR method was found to be 52 days. The results have shown that the time-lapse of submersion and quality of fingerprint developed are inversely prepositional to each other. Although pond water submerged substrates showed good quality developed fingerprints for a longer period than other mediums but with increasing period of submersion the quality degraded.]]>
