The accuracy of textile damage analyses was evaluated by laboratory tests carried out by trained experts. The analyzed damages were prepared by various methods, including stabbing, cutting, shooting, heating/burning, etc. A number of damages were aged by household washing and tumble-drying procedures, addition of blood, or burying. The samples were analyzed by routine laboratory evaluation. The results indicate that the properties of a damage provide a good indication of the way a textile had been damaged. Nevertheless, scoring of the answers is not straightforward. Results indicated that examiners evaluated damages on different levels of specificity and thereby showed the latent need for a more systematic approach to damage classification. The second part of the current contribution therefore presents the classification scheme we developed. This classification scheme aims to guide examiners during examination and accommodates the vast majority of textile damages observed in forensic casework. Each of the proposed classes is defined, relevant literature in each of the classes is reviewed, and the characteristics that can be expected after different damaging actions are explained. Finally, we share some ideas for further investigations.
由训练有素的专家进行的实验室测试评估了纺织品损伤分析的准确性。所分析的损伤通过多种方法制备,包括刺伤、切割、射击、加热/燃烧等。一些损伤通过家庭洗涤和滚筒烘干程序、添加血液或掩埋进行老化处理。通过常规实验室评估对样本进行分析。结果表明,损伤的特性很好地表明了纺织品的受损方式。然而,答案的评分并不简单。结果表明,检查人员对损伤的评估具有不同程度的特异性,从而表明对损伤分类采用更系统方法的潜在需求。因此,本论文的第二部分介绍了我们开发的分类方案。该分类方案旨在在检查过程中指导检查人员,并涵盖法医案件工作中观察到的绝大多数纺织品损伤。对每个提议的类别进行了定义,回顾了每个类别中的相关文献,并解释了不同损伤行为后可能出现的特征。最后,我们分享了一些进一步研究的想法。
