Abies Webbiana ( Thalisapathri) - Latent Fingerprint Method On Various Surfaces - An Innovative Technique.

Abstract

Introduction: Fingerprints are a distinctive feature of individuals and are one of the oldest and most widely accepted forensic evidence used to establish personal identity. The most familiar prints encountered at the scene of the crime are the latent prints. These are invisible prints retained on a substrate on account of various secretions from the body. Fingerprints can be deposited on a number of substrates, broadly classified as porous, non-porous, and semi-porous surfaces.

Aim: The aim of the study was to evaluate the latent fingerprint using Thalisa Pathri powder on various electronic surfaces.

Materials and method: The sample is taken in powder form. Based on previous research work articles will be collected and work was carried out accordingly. Thalisa Pathri is collected and dried for 7 days. After that allow the plant to shade dry for 3 days and then convert to powder form. Here surfaces were randomly selected to make a finger  impression on electronic surfaces such as mobile cover, laptop, mouse, television, speaker, iPad, charger, etc.

Results: The fingerprints are fine and clear on surfaces of television and microwave oven. The ridges are partially visible on the surfaces of the mouse and refrigerator. In surfaces like phone, laptop charger and telephone the fingerprints are smudged and in some the ridges are not clear.

Conclusion: Thalisa pathri powder which is easily available and simple can be used successfully on various surfaces to develop prints in crime investigation.
