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.

从多学科角度对疑似简易爆炸装置（IED）的法医分析：ENFSI 2023演习的组织和结果。

测试材料的跨学科检查需要仔细考虑法医程序如何相互影响。这种影响可以是直接而明显的，也可以是间接而微妙的。多学科协作练习（MdCE）应该测试法医实验室解释这些困难的能力。因此，建立MdCE的方式应该考虑应用程序（即法医学科的顺序）如何影响结果（即恢复痕迹的能力）。基于以往的经验教训，本文总结了ENFSI 2023多学科协作演习（2023- mdce）的概念、规划、设计、准备、实施、协调和评估，涵盖了一系列法医学科，特别是DNA、指纹、爆炸物、纤维和头发形态分析。演习包括一个用黑色胶带包裹的玻璃罐，代表一个简易爆炸装置。分析结果强调：a)联合初步光学检查的重要性；B)炸药/指纹取样策略的一些关键问题；C)可能包含摩擦脊细节的接触标记对与组织者存放的物品不同的物品的潜在影响；D)强调在标记、证物和/或痕迹中避免差异的重要性，因为这与科学法医结果的传播策略有关。此外，为那些可能希望进行这种合作练习的人提供了建议和建议。

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.
