Abstract

The disulfur dinitride (S₂N₂) process has demonstrated an ability to develop fingermarks on a range of metal substrates. However, the commercialised system ‘Recover Latent Fingerprint Technology (LFT)’, which utilises this scientific process, has not been evaluated on stainless steel kitchen knives, an item commonly encountered in major crime cases in the United Kingdom. This paper reports on the planted fingermark experiments conducted to investigate the Recover LFT performance relative to, and after, other visualisation processes; such as Superglue Fuming (with and without Basic Yellow 40 dye staining), Carbon-based Powder Suspension, Basic Violet 3 and Acid Violet 17. The results from this study indicate that Recover LFT is a promising process for fingermark visualisation on the blades of stainless steel kitchen knives. Additional studies are required in order to fully assess and determine the benefits of the process and to optimise the position in a sequential processing chart. This novel process would also benefit from a deeper understanding of the underlying chemistry.

期刊介绍： Science & Justice provides a forum to promote communication and publication of original articles, reviews and correspondence on subjects that spark debates within the Forensic Science Community and the criminal justice sector. The journal provides a medium whereby all aspects of applying science to legal proceedings can be debated and progressed. Science & Justice is published six times a year, and will be of interest primarily to practising forensic scientists and their colleagues in related fields. It is chiefly concerned with the publication of formal scientific papers, in keeping with its international learned status, but will not accept any article describing experimentation on animals which does not meet strict ethical standards. Promote communication and informed debate within the Forensic Science Community and the criminal justice sector. To promote the publication of learned and original research findings from all areas of the forensic sciences and by so doing to advance the profession. To promote the publication of case based material by way of case reviews. To promote the publication of conference proceedings which are of interest to the forensic science community. To provide a medium whereby all aspects of applying science to legal proceedings can be debated and progressed. To appeal to all those with an interest in the forensic sciences.
