Abstract

Stab wound analysis is a relatively new field of study in forensic science, and there is currently much debate regarding the effectiveness of the analysis due to a lack of validation studies. Furthermore, the underlying viewpoints on the success of stab wound analysis vary. Examination of cut marks, for example, can reveal a variety of characteristics which can be used to determine the type of weapon that was used to inflict them. However, published studies are not consistent when identifying knife blade characteristics, instead considering a wide variety of morphological aspects and their potential value in forensic scenarios. The existing research methodology is therefore inadequate to reliably inform in such contexts, and future experimental design should be influenced by the conditional variance in stabbings in order to provide reliable findings.

The research presented here takes a systematic approach to the problem, compiling the published literature (up to September 2023) on the use of different imaging methods applied to stab wound examination to create a taxonomy to examine trends in methodological approaches in both research and investigative settings. This approach identified that published studies could be classified as either morphological or morphometrical, and further sub-classified based on their degree of success and the findings reached. This emphasises the importance of prioritising research into mark data, and the need for a multi-technique, multi-disciplinary approach. A decision tree was created to illustrate which mark attributes should be studied for which purpose, and using which imaging method(s). Furthermore, the research presented identifies two key areas in stab wound research which should be the focus of standardisation efforts, namely methodological procedures and mark characteristic collection. Knife markings are difficult to interpret, but further research and standardisation of kerf mark analysis, as highlighted here, will improve the efficiency and reliability of both forensic investigations and future experimental studies.

不同成像技术在刺伤分析中的应用
在法医科学中,刺伤分析是一个相对较新的研究领域,由于缺乏验证性研究,目前关于分析的有效性存在很多争论。此外,关于刺伤分析成功与否的潜在观点各不相同。例如,对切割痕迹的检查可以揭示各种特征,这些特征可用于确定造成这些痕迹的武器类型。然而,已发表的研究在识别刀刃特征时并不一致,而是考虑了各种形态方面及其在法医场景中的潜在价值。因此,现有的研究方法不足以在这种情况下提供可靠的信息,为了提供可靠的结果,未来的实验设计应该受到刺穿条件方差的影响。本文提出的研究采用了一种系统的方法来解决这个问题,汇编了已发表的文献(截至2023年9月),这些文献涉及使用不同的成像方法进行刺伤检查,以创建一个分类法,以检查研究和调查环境中方法学方法的趋势。该方法确定已发表的研究可以分为形态学或形态计量学两类,并根据其成功程度和所获得的发现进一步进行分类。这强调了优先研究标记数据的重要性,以及对多技术、多学科方法的需要。创建了一个决策树来说明应该研究哪些标记属性用于哪些目的,并使用哪种成像方法。此外,提出的研究确定了刺伤研究的两个关键领域,即方法学程序和标记特征收集,这应该是标准化工作的重点。刀痕很难解释,但进一步的研究和标准化刻痕分析,正如这里强调的,将提高法医调查和未来实验研究的效率和可靠性。

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.
