The examination of damage to a paper towel, an item of evidence in a murder case, is described. Simulations performed with selected tools and the observation of the lacerations present on the towel permitted to infer that they were originated by cleaning of a pointed and sharp implement. Some marks, considered characteristic of scissors, were detected on the exhibit. This experimental outcome resulted critical in challenging the declarations of the suspect. A rather significant analogy between damage examination on paper towels and on textiles was established.
本文描述了对一起谋杀案中的证物纸巾损坏情况的检验。使用选定工具进行的模拟以及对纸巾上撕裂伤的观察表明，这些撕裂伤是由清洁尖锐利器所致。在证物上检测到了一些被认为是剪刀特征的痕迹。这一实验结果对于质疑嫌疑人的供述至关重要。在纸巾和纺织品的损坏检验之间建立了相当显著的类比关系。
