This study evaluates how fabric composition and colour affect the effectiveness of biological trace and lubricant visualisation using the Foster + Freeman Crime-lite® ML PRO device. Various fabrics and substances were analysed to determine the optimal conditions for detection. Both natural and synthetic fabrics were tested under different lighting conditions provided by the device. The visibility of biological traces and lubricants was examined across multiple wavelengths, including the visible and infrared spectra. Key parameters such as fabric composition, colour, and stain concentration were assessed. The findings indicate that both the chemical composition and colour of fabrics play a significant role in the effectiveness of biological trace and lubricant visualisation. The Foster + Freeman Crime-lite® ML PRO device was effective in detecting biological traces when optimal conditions were met. However, the variability in results highlights the need for tailored approaches depending on fabric type and colour.</div></div>","PeriodicalId":36331,"journal":{"name":"Forensic Science International: Reports","volume":"11 ","pages":"Article 100401"},"PeriodicalIF":0.0,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143136170","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Legal trade in wild animals and their derivatives is based on sustainable practices, ensuring that specimens are taken in quantities that do not threaten population stability. Unregulated or illegal international trade can jeopardise the survival of certain species by depleting wild populations. Forensic analysis is crucial in distinguishing between legal and illegal trade, particularly by determining the geographical origin or age of a specimen through methods such as stable isotope and radiocarbon analysis. The tanning process, which converts mammalian raw hides into valuable fur skins, involves the use of aggressive chemical reagents. These reagents, if absorbed by the hair or skin, can alter the original isotopic signatures, complicating forensic efforts. The extent of these alterations is not yet fully understood. The novelty of our approach lies in the fact that, for the first time, we have measured the step-by-step changes in isotopic composition throughout each individual phase of the tanning process. Previous studies have typically focused only on raw hides and final products. Additionally, we compared different tanning methods applied to a single hide. Using a leopard skin, we documented potential isotopic shifts in ¹⁴C, ²H, ¹⁸O, ¹⁵N and ¹³C during the tanning process, employing accelerated mass spectrometry and stable isotope mass spectrometry. Our preliminary findings suggest that the tanning process induces slight shifts in both stable and radioactive isotope ratios.</div></div>","PeriodicalId":36331,"journal":{"name":"Forensic Science International: Reports","volume":"10 ","pages":"Article 100398"},"PeriodicalIF":0.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143151046","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This case report highlights the importance of interdisciplinary approaches to achieve the identification of skeletonized individuals. An abandoned grave vault in a small town of Nièvre, central-east France, uncovered three skeletons associated with <em>militaria</em>. Initially, the remains were believed to belong to three Senegalese Riflemen executed nearby in 1940, but some of the evidence appeared contradictory. The aim of this study is to determine whether these three skeletons were the three Senegalese Riflemen or other individuals. Through an interdisciplinary approach, combining the position of the bodies in the vault, anthropological analysis of the human remains, and archival research, it was determined that the three bodies belonged to the same family. The remains were those of an illegally repatriated body of a soldier from the battlefields of WW1, together with his parents. It is suggested that they illegally repatriated him from the battlefield/cemetery and then buried him in the family vault, and later, when the parents passed away, they were also buried alongside him.
