Abstract

context: Fingerprints are used as reliable evidence in criminal and civil investigations all around the world. There are several methods available for detecting latent fingerprints. Powder dusting is one of the most used methods. The current research began with the need to solve a challenge that arose from everyday actual forensic work. The latent print on diverse surfaces created for this investigation was developed using talcum powder. Talcum powder is easily available at home and can used by Investigating Officer if fingerprint powders like charcoal powder, aluminum powder, gray powder, fluorescence powder, magnetic powder and others are unavailable. aims: The aim of this research was to see how effective talcum powder can be as a low-cost, non-toxic fingerprint powder, especially in areas where conventional powders are scarce. materials & method: 20 samples of latent fingerprints were developed from varied surfaces using a camel hairbrush and powder-dipping techniques. Moreover, adhesive tape was used to lift and collect the fingerprints on to fingerprint cards. results: Twenty substrates with diverse surfaces, color, and nature had been chosen to deposit fingerprints, and their development efficiency as investigated using talcum powder. The majority of the fingerprints that were created had big contrast and transparency. conclusion: The talcum powder can be an effective and inexpensive substitute for other fingerprint powders, particularly in the case of shortage of other powders. key messages: The non-toxic talcum powder approach is simple to use, inexpensive and effective. The results of this investigation demonstrate that, with a little bit of fingerprint expertise and training, police officers can utilize a readily available product like talcum powder to identify latent fingerprints.
