Abstract

Interdisciplinary examination of test materials requires careful consideration of how forensic routines can influence each other. This influence can be direct and obvious, or indirect and subtle. A multidisciplinary collaborative exercise (MdCE) should test a forensic laboratory’s ability to account for these difficulties. Therefore, the MdCE should be set up in a way that considers how the applied procedure (i.e., the sequence of forensic disciplines) can impact the outcomes (i.e., the ability to recover traces).

Building on lessons learned from a previous experience, this article summarises the concepts, planning, design, preparation, implementation, coordination and evaluation of the ENFSI 2023 Multidisciplinary Collaborative Exercise (2023-MdCE) covering a range of forensic disciplines, specifically DNA, fingerprints, explosives, fibres, and hair morphological analysis.

The exercise consisted of a glass jar with black adhesive tape around it, representing an improvised explosive device. The analysis of the results highlighted: a) the importance of a joint preliminary optical examination; b) some critical issues regarding the explosives/fingerprint sampling strategies; c) the potential impact of contact marks that may contain friction ridge detail on items that were different from those deposited by the organiser; d) the importance of avoiding discrepancies in labelling exhibits and/or traces is emphasised as it is related to the communication strategy of scientific forensic results.

Additionally, recommendations and suggestions are provided for those who may wish to undertake such a collaborative exercise.

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.
