The majority of GSW research is centered on the cranium or thoracic bones, as they are most affiliated with fatal injuries. The present study examined differences in fragmentation and trauma characteristics on long bones caused by two ammunition types. White-tailed deer (Odocoileus virginianus) tibiae (n = 50) were encased in 10% ballistic gelatin, and 9 mm ammunition from a handgun and 5.56 mm ammunition from an assault rifle were fired from 3 yards (~2.74 m). Due to the higher potential wounding energy, it was anticipated that tibiae impacted by 5.56 mm ammunition would exhibit a greater degree of fragmentation and obscure fracture patterns. Conversely, fragmentation patterns from 9 mm ammunition were expected to be more discernible, given the lower energy transfer and smaller caliber, allowing for easier classification of fracture patterns. A Mann-Whitney U-test revealed 5.56 mm ammunition caused more fragmentation than 9 mm (p = 0.002). False butterfly fractures were observed in 48% of the 9 mm sample and 4% of the 5.56 mm sample. Chi-square tests for independence showed that all but stepped breakout (χ2 [1] = 1.299, p = 0.254) had a statistical association with an ammunition type. The present study found significant differences between the frequency of observed ballistic characteristics and ammunition type within the sample; however, due to similarities, it is not recommended to use fracture pattern analysis as a method of classifying ammunition type.","PeriodicalId":94080,"journal":{"name":"Journal of forensic sciences","volume":" ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144805519","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, this field would greatly benefit from baseline data regarding the early stages of body exposure before insects arrive (the pre-colonization interval or pre-CI) to further refine PMIMIN estimations. The goal of this project was to generate a human-specific pre-CI baseline dataset covering a range of ambient temperatures. Donated human remains (N = 62) were placed at the University of Tennessee Anthropology Research Facility across all seasons over a 3-year period and allowed to be colonized naturally by local blow flies. Initial oviposition events were recorded, and insect eggs from a subset of donors were reared for species identification. Ten donors were randomly selected to constitute the first validation cohort, using the remaining 52 donors as the training dataset. A second validation cohort consisted of 13 additional donors with unknown pre-CI data. The most important pre-CI predictors were statistically grouped, and a 95% confidence interval was determined. Minimum temperature was found to be a statistically significant predictor of the pre-CI (p = 0.000, R2 = 0.608), and the pre-CI dataset produced accurate estimations for samples collected above a minimum daily temperature of 22°C. The addition of the pre-CI to larval age estimations significantly improved estimation accuracy (χ = 106.19, df = 4, p < 0.001). The generation of an error rate for this time interval aligns with the recommendations for strengthening forensic science set forth by the National Research Council.","PeriodicalId":94080,"journal":{"name":"Journal of forensic sciences","volume":" ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144801355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tryptase, a mast cell-derived protease, has emerged as a potential biomarker for fatal anaphylaxis. This systematic review critically examined 40 studies published between 2014 and 2024, including both biochemical and immunohistochemical analyses. Literature was identified through comprehensive searches of PubMed, Scopus, and Web of Science, following PRISMA guidelines. Biochemical studies consistently reported elevated postmortem β-tryptase levels in anaphylaxis-related deaths, with proposed diagnostic thresholds ranging from 30.4 to 64 μg/L. A diagnostic threshold of 53.8 μg/L demonstrated particularly strong discriminative capacity (AUC = 0.98; p < 0.001). Immunohistochemical analyses revealed an increased number of tryptase-positive mast cells in lung, pharynx, and skin tissues, but standardized protocols or quantification criteria were lacking. Notably, mast cell localization around bronchioles or vascular structures was more frequent in anaphylaxis cases. Despite promising findings, substantial heterogeneity in postmortem interval, sampling site, and analytical methodology limits the generalizability of current evidence. Elevated tryptase levels were also documented in non-anaphylactic deaths, underscoring its limited specificity. Overall, tryptase can support the postmortem diagnosis of anaphylaxis when interpreted in the context of autopsy findings, scene investigation, and clinical history. However, it should not be used as a standalone marker. Standardized protocols and combined biomarker panels are urgently needed to enhance diagnostic reliability in forensic settings.","PeriodicalId":94080,"journal":{"name":"Journal of forensic sciences","volume":" ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144796529","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such easy access raises severe moral and legal concerns around the potential for malicious image editing. Overcoming this difficulty will need the development of innovative approaches for the quick detection of changes in high-quality photographs. This paper proposes a new way to solve this problem by analyzing chrominance discontinuities in spliced regions, DWT, and unique histograms based on local binary patterns. To start extracting the luminance and chrominance components, we change the input image's color space from RGB to YCBCR. Then, using discrete wavelet transformation, the blue and red chromaticity levels were converted into wavelet bands. We compute histograms using the CB and CR DWT high-frequency bands. The next step is to use feature fusion methods to merge the CB and CR feature vectors from each high-frequency band after we change the histograms into vectors. Finally, we train a Support Vector Machine (SVM) using the combined color characteristics. A binary SVM trained to identify spliced images between original and spliced images has been produced. Improving upon existing methods, the proposed method achieved up to 98.49% accuracy on CASIA v1.0, outperforming existing benchmarks, that is, 97.33% on DVMM and 98.25% on Casiav2.0, thereby enhancing splicing forgery detection. This method contributes to media forensics by providing a reliable tool for detecting tampered images, which holds significant relevance in legal investigations and digital content authentication.","PeriodicalId":94080,"journal":{"name":"Journal of forensic sciences","volume":" ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144755514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although its working solution is typically pre-prepared, it has several drawbacks: it can dissolve printing ink and handwritten text, and it often causes thermal paper to darken. In light of these drawbacks, this study introduces and evaluates a solvent-free fingerprint development method by applying superfine ninhydrin powder (ASNP). In this approach, finely ground ninhydrin powder is directly applied to paper surfaces, followed by controlled heating and humidification to facilitate the diffusion of ninhydrin molecules into the paper fibers for fingerprint development. Seven types of paper were evaluated, including kraft paper, newspaper, carbonless copy paper, magazine, copying paper, thermal paper, and coated art paper. The ASNP method was compared with the traditional ninhydrin solution under two conditions: 60°C at 40% relative humidity (RH) and 50°C at 65% RH. The condition of 50°C and 65% RH yielded improved fingerprint development, with most ASNP prints becoming visible within 6 h. After 24 h, the performance of the ASNP method was comparable to that of the traditional solution. This ASNP technique offers several advantages: it eliminates the need for a pre-mixed working solution, reduces solvent costs, avoids solvent-induced damage and environmental hazards, and results in only minimal background staining. Moreover, it can be effectively applied to thermal and carbonless copy papers.","PeriodicalId":94080,"journal":{"name":"Journal of forensic sciences","volume":" ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144746648","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This can occur in various circumstances, including homicide, suicide, and autoerotic accidents. While forensic medical specialties effectively determine the cause of death in such cases, establishing the manner of death remains challenging. Previous research has highlighted a need for differentiation that goes beyond contextual information and autopsy findings. This study employs epidemiological methods to examine injury prevalence and statistical differentiation of neck compression deaths, aiming to quantify the likelihood of injury across various homicidal, suicidal, and accidental neck compression scenarios. Using data from 266 cases across homicidal ligature and manual strangulation, suicidal neck compression, and autoerotic neck compression, the study investigates injury and associated findings, prevalence, patterns, and probabilities across anatomical regions commonly injured due to neck compression. Results indicate that the odds of injury to various regions of the head and neck are influenced by the manner of death, with homicidal intent often presenting a higher prevalence of injury as well as increased odds of injury. Such statistical differentiation could assist in determining the manner of death in cases of masked homicide, when remains are alternatively preserved, or where there are no reliable witnesses. This research highlights the role of epidemiology in complementing forensic medical specialties, offering quantifiable evidence to assist in medico-legal investigations and expert testimony.","PeriodicalId":94080,"journal":{"name":"Journal of forensic sciences","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144719292","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
