AbstractFingerprint evidences are perhaps the most common type of physical evidences found at crime scene. Their development and identification helps to prove criminal physical presence at scene of crime. It is extremely difficult for a criminal to commit the crime without having behind his fingerprint. The latent fingerprints are the most pronounced category of fingerprints which serves as an evidence. This review paper focuses upon conventional and advanced analytical techniques used in the detection and comparison of latent fingerprints for easier decipherment. Now a day, criminals nowadays use latex gloves to hide their identity in order to reduce their chances of being sinful. Although it work act as a protective covering but when removed, they are typically peeled off preserving the fingerprints evidences on them without smearing. Thus, those prints were developed by using various physical
and chemical methods and then photographed for investigation and the comparison purpose. Hence, these gloves at crime scene can serve as a direct evidence to catch the culprit. There are several non-destructive physical methods which are used for the development of latent fingerprints which includes the use of a variety of powders such as
black powder (on dark surfaces), white powder(on light surfaces), fluorescent powder (Multicolored surfaces) etc. whereas the destructive method includes the chemical treatment by cyanoacrylate, small particle reagent, ninhydrin etc.Keywords: Charred/Burnt Documents; Decipherment; Ammonia Solution; Forensic Document Examination.
