Abstract
Criminal offenders Has basic goal not to be detected after committing crime, Criminals try to hide the evidences by throwing in water bodies, as they think that valuable evidences get easily destroyed but now days, fingerprint visualization is possible from submerge water. In the study three different reagents were used for comparison i.e, Black powder, Cyanoacrylate Fuming and Fluorescent powder, at different time intermission (day 1, 10, 20, 30, 40 and day 50). After comparing different reagent it was found that Fluorescent Powder gives best result followed by Cyanoacrylate then Black powder. Keywords: Fingerprint Forensic Science, Nonporous surface, Submerge
Introduction
Finger print is an impression left by the friction ridges of a human finger. It is key evidence in forensic science for purpose of criminal identification. Fingerprint is produce by secretion of natural substance which is present in the ridges of epidermal, it is the unique impression which is left by human friction ridges when come upon touch with any object, it is often found on crime scene which help to link with the criminal. Various substance such as 99% water, organic and inorganic content are the part of natural fingerprint residue (Girod et al., 2012). Fingerprint deposition in surfaces due to secretion of the following type of gland from the human body i.e. eccrine, apocrine and sebaceous gland (Knowles, 1978). This type of evidence is hardly visible and therefore visualization techniques have to be called into action. Fingerprints may be classified as latent (invisible), visible and plastic prints (Lee and Gaennslen, 2001). To detect latent print visualization technique is needed because it’s very hard to detect (Badiye and Kapoor, 2015). Formed the chance fingerprint when the sweat pores of the papillary ridges leave a deposition of secretion on a surface with which the finger has been brought into contact (Thomas, 1978).
Criminal offenders have a fundamental goal not to leave any traces at the crime scene. It It is believe by the criminal that evidence recovered from underwater have no forensic value therefore, they have intention to destroyed items by throwing underwater (Trapecar, 2012). Therefore, they have intention to destroyed items by throwing underwater (Trapecar, 2012). So there is need have examine evidences which is recovered from underwater by forensic science authorities. For latent print development choice of visualization depend on type of surface, effectiveness, efficiency ease of use and health safety factor (Bramble and Brennan, 2000).
