Latent fingerprint development by using cost effective incense sticks (Agarbatti) ASH

Abstract

The powder method is the most convenient method for fingerprint development. Various powder methods for developing fingerprints have existed throughout the last decade and numerous powders have been experimented with over time. For this study, a bunch of Alaukik Agarbatti (local incense stick brand of Gujarat, India) were burnt properly and ash of burned incense sticks (Agarbatti) was collected on a sheet of paper. It was crushed by smooth hands and converted into fine powder. The formed powder was applied by the use of camel hairbrush to the latent fingerprints taken from the subjects. Photography was done in proper contrast. The application of burned incense stick powder is a novel material for this kind of study, it has been not done before. The impression of fingerprints obtained using burned incense stick powder was clear and sharply visible on both non-porous and porous surfaces. Ridge patterns in developed impressions were comprehensible and identifiable. Due to their contrast, a black or grey-coloured powder could be easily seen on a colourful background. Developed fingerprints were appropriate for tape-lifting and comparison after photography. This method is best due to its easy availability, less cost, and effectiveness. This method also suggests an approach towards environmental waste management.
