The analytical characterization of such adhesive tape evidence can be useful for assessing potential contact between the suspect, the victim, and/or the crime scene. However, adhesive tapes frequently serve as substrates for fingermarks, and the examination of these impressions takes precedence over the characterization of the tape due to the higher evidentiary value associated with fingermarks. This study evaluated the efficacy of commonly available fingermark development methods for fingermarks on adhesive tapes and investigated their effects on the characterization of the adhesive tapes using ATR-FTIR spectroscopy. Gentian violet and iodine fuming were able to develop fingermarks on various types of tapes with good ridge detail clarity and good contrast. These techniques were also compatible with the characterization of the tapes using ATR-FTIR spectroscopy. Iodine fuming did not introduce any additional peaks in the ATR-FTIR spectra. Gentian violet presented a few minor additional peaks at 1644, 1586, and 963 cm-1. An additional preliminary study on the effect of selected fingermark techniques on chemometric prediction of adhesive tapes was conducted. The results showed that iodine fuming resulted in more prediction accuracy compared to gentian violet. The findings of this study will contribute to determining the strategic choice for the fingermark development on adhesive tapes as well as its subsequent characterization and also strengthen the interpretation of adhesive tape evidence using chemometrics.","PeriodicalId":94080,"journal":{"name":"Journal of forensic sciences","volume":" ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145002286","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}

These samples are usually collected using the swabbing method from the lips. Sometimes, the same samples are stored in forensic laboratories for years due to a backlog of cases, which affects the samples' originality. Therefore, in this study, a comprehensive study of the wearing and storage effects was conducted to assess the period up to which lipstick traces can be linked to their source by analyzing 20 brands of red lipsticks using ATR-FTIR spectroscopy and chemometric tools. The study was divided into two phases. In Phase I, samples were collected using the swabbing method from the lips of volunteers after 5 min, 1, 3, and 5 h of application, followed by ATR-FTIR spectroscopic analysis. Similarly, in Phase II, the same swabs were kept for 1 year to investigate their aging process, followed by ATR-FTIR spectroscopic analysis. The results showed that all the pristine samples can be discriminated with 100% LDA accuracy. The built training model was also validated, which showed 95% accuracy. Chemometric prediction of the worn samples yielded 80% accuracy for Phase I. However, a reduced accuracy (45%) was observed for Phase II due to the drying effect and loss of sample over time. It can be concluded that these types of samples must not be stored for a longer duration in real-case scenarios, so that the authenticity of the evidence is retained.","PeriodicalId":94080,"journal":{"name":"Journal of forensic sciences","volume":" ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144984158","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}

Arizona (1966) protects waivers in police custody from potential self-incrimination unless the waiver decision was knowingly and intelligently effectuated. Despite extensive research on Miranda comprehension, very little is known about these crucial waiver decisions. This study explores new ground for formerly incarcerated persons (FIPs) and their capacity for knowing and intelligent waivers. In a Prolific investigation, 182 FIPs were recruited, with most having multiple arrests and subsequent incarcerations. They were tested on the Standardized Assessment of Miranda Abilities (SAMA), the best validated measure of Miranda abilities for adult detainees. Results of a linear discriminant analysis indicated that the Miranda-proficient reasoning group was predicted by strong Miranda-relevant vocabulary and low scores on the Trust in Law Enforcement (TLE) subscale. Contrastingly, the Miranda-compromised group demonstrated significantly less advanced Miranda vocabulary with concomitantly high TLE scores. Despite criminal backgrounds, TLE overrode other considerations for Miranda waivers. Based on a qualitative analysis, Miranda-compromised FIPs seriously overestimated their own abilities to handle police questioning, whereas Miranda-proficient FIPs appeared more skeptical of any advantages of waiving silence/counsel. In conclusion, this Miranda-compromised group held seemingly more trusting views of arresting officers and saw more benefits to waive their rights than their Miranda-proficient counterparts.","PeriodicalId":94080,"journal":{"name":"Journal of forensic sciences","volume":" ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144983934","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 typically considered benign and reversible following tumor removal, the syndrome can result in severe life-threatening compromise if unrecognized or untreated. Unlike the classical Meigs syndrome, which has occasionally been associated with fatal outcomes, no deaths related to pseudo-Meigs syndrome due to benign tumors have been previously reported. This report presents the sudden death of a young adult woman who complained of acute shortness of breath and died shortly thereafter. Postmortem examination revealed more than 2.5 L of serous fluid within the thoracic and abdominal cavities, severe pulmonary collapse, and a markedly enlarged uterus containing a large leiomyoma. Histologic evaluation confirmed the tumor as a uterine leiomyoma. The findings observed at autopsy account for the proposed pathophysiologic mechanisms of death, in which impaired gas exchange and increased intrathoracic pressure likely compromised cardiac output, leading to death. These findings support a diagnosis of pseudo-Meigs syndrome with fatal cardiopulmonary consequences. This case represents the first fatality attributed to pseudo-Meigs syndrome associated with a benign tumor. Awareness of this potential outcome is essential for both clinicians and forensic pathologists when evaluating individuals with large benign pelvic tumors and unexplained cavity effusions.","PeriodicalId":94080,"journal":{"name":"Journal of forensic sciences","volume":" ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144984121","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}

Using a quantitative, quasi-experimental design, we analyzed 60 images across three iPhones (running iOS 14.2 and 14.4) to compare downloads to the Files folder and the Photos application. Controlled tests validated measurement sensitivity, while results revealed consistent image content integrity: cryptographic Secure Hash Algorithm 256 (SHA256) stream hashes matched control copies (100%), confirming unchanged pixel data. Additionally, Multiscale Structural Similarity Index (MS-SSIM) scores remained at 1.0, indicating no perceptible degradation in image quality. However, file container hashes were altered within the Photos application (100%) but remained unchanged in the Files folder (0%), reflecting iOS structural modifications. Uniform MS-SSIM scores precluded meaningful regression analysis. Based on our test conditions, the findings suggest forensic workflows comply with standards like Daubert because the transfer preserves content integrity.

By eliminating these artifacts, anti-forensic approaches seek to elude forensic detectors. The field of digital image forensics has many difficulties due to the growing sophistication of anti-forensic tactics. Two popular techniques for modifying image characteristics are contrast enhancement and median filtering, which are frequently used to hide signs of manipulation. Therefore, a solution for identifying anti-forensic techniques is urgently needed. This paper presents a multi-class forensic Deep Convolutional Neural Network (DCNN) architecture that combines domain-specific feature streams and residual-domain pre-processing. This pre-processing is designed to reduce image content and highlight manipulation artifacts in order to detect and classify various kinds of image alterations. The DCNN is made to recognize and extract minute manipulation artifacts that are hidden in pixel-level patterns and invisible to the naked eye. The Boss Base dataset is used for training and testing. Experimental assessments show that the proposed model can recognize images that have been exposed to median filtering and contrast enhancement anti-forensics with a good accuracy of 96.42%, even with different levels of manipulation intensity. The proposed model integrates intelligent pre-processing with domain-tailored streams, which makes it robust against compression and is capable of distinguishing between a wide range of complex manipulation types. This strategy fulfills the increasing demand for automated and precise detection techniques in the fight against anti-forensic activities by offering a reliable tool to digital forensic investigators.","PeriodicalId":94080,"journal":{"name":"Journal of forensic sciences","volume":" ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144983991","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, inconsistencies regarding how these motives are defined and classified may hinder the ability to understand the driving factors behind homicide. Developing a classification system that defines and organizes commonly used motives into superordinate categories may improve research focused on homicide. The current study sought to develop such a classification system, titled the Homicide Offender Motive Scale (HOMS), based on a qualitative systematic review. Databases including Medline, PsychINFO, and Google Scholar were reviewed to identify all homicide motive studies published prior to February 2024. Multiple reviewers independently assessed the quality of the studies using an empirical appraisal checklist. Seventy-seven studies comprising 143 motives with varying definitions were included. The reviewers then conducted a thematic analysis to identify descriptive and analytical themes for the 143 motives described in the studies. Following empirical guidelines, the motives were synthesized into 21 descriptive themes with operational definitions and criteria. Perfect interrater reliability of these definitions and criteria was then established in an independent sample of 200 adult homicide offenders. Finally, the 21 descriptive themes were grouped into four distinct analytical themes, which were also partly based on an existing criminological classification system. The 21 descriptive themes represent commonly observed motives across different homicide cases. The four analytical themes are superordinate categorizations of the specific motives. The empirical nature of the HOMS may offer a unified typology of homicide motive for researchers to expand upon.","PeriodicalId":94080,"journal":{"name":"Journal of forensic sciences","volume":" ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144983799","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}

It may result from trauma or occur spontaneously in association with underlying disease conditions. When no source of fatal hemorrhage is identified, the implications extend across forensic, criminalistic, legal, and ethical domains. Idiopathic spontaneous intraperitoneal hemorrhage (ISIH), historically known as abdominal apoplexy, is characterized by fatal hemoperitoneum in the absence of trauma or known nontraumatic causes of intraabdominal bleeding. Rupture of a small intraabdominal vessel is suspected; however, the bleeding source usually remains unidentified. We report the case of a 45-year-old female with cirrhosis who succumbed to ISIH. Autopsy revealed massive hemoperitoneum and signs of exsanguination. Careful dissection of the abdominal cavity identified hemorrhagic ectopic venous varices beneath the right diaphragmatic arch, covered by an organized blood clot. Histological analysis confirmed recent hemorrhage and demonstrated suspected rupture of the parietal peritoneum near dilated ectopic venous varices. This case is evaluated in the context of pathophysiology, etiological theories, diagnostic limitations, potential contributions of imaging modalities, and forensic relevance. To our knowledge, this is the first reported case of ISIH with dual confirmation-both gross and histological-of hemorrhage originating from ectopic varices. These findings testify that rupture of ectopic venous varices may cause fatal hemorrhage in patients with cirrhosis and underscore the necessity of meticulous autopsy and histopathological correlation.","PeriodicalId":94080,"journal":{"name":"Journal of forensic sciences","volume":" ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144984138","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}
