Abstract

Abstract: Successful development of latent fingerprints can be helpful in solving the case but in case where fingerprints are smudged, distorted or overlapped, the question arises whether it is still possible to identify the person apart from dermatoglyphic features. Sweat residue present in the latent prints is supposed to have quite good quantity of cellular material which if analyzed properly can be used to generate forensic DNA profile of the individual and may answer the queries related to the effect of reagents used to develop the prints, as they may have a significant effect on the process of examination of this evidentiary material. In the present work an effort has been made to summarize the published review of literature on this aspect of personal identification. Highlights: Extraction of DNA depends upon time lapse between the latent fingerprint development and DNA extraction. Surface on which the latent fingerprints are present has an effect on DNA isolation from the developed fingerprints. Only shortwave UV Light source which is used to decipher latent fingerprint reduces DNA quantity as it degrades DNA. Magnetic powders for fingerprint development were found to effect least in DNA extraction from developed latent.
