This study examined latent print evidence using reflective ultraviolet imaging systems (RUVIS) in post-blast forensic investigations.

Abstract

As terrorist bombing incidents continue both domestically and internationally, the need to identify those responsible grows. Currently, the majority of post-blast forensics focuses on identifying the explosive materials used and their amount, determining the size of the blast radius, and identifying human remains. Latent prints are commonly located on tape and batteries. Less attention is focused on examining post-blast materials because of the assumption that the intense heat of the explosion would obliterate them. Research using reflective ultraviolet imaging systems (RUVIS) revealed the ability of latent print evidence to survive intense thermal conditions. A potential application of this technology includes a nonintrusive method of locating and capturing friction ridge impressions from devices and munitions, prior to on-site destruction.
