However, in Sub-Saharan Africa, the field has developed within a framework shaped by colonial histories, Western methodologies, and systemic underinvestment in local capacity. This article critically examines the need to decolonise forensic odontology in the region, proposing a comprehensive reform agenda grounded in four intersecting domains: historical legacies, indigenous knowledge integration, ethical considerations, and policy reform. It highlights how colonial-era forensic practices continue to influence current protocols and legal standards, often to the detriment of scientific accuracy and justice. By recognising and incorporating traditional dental knowledge, such as ritual dental modifications and community oral histories, the field can be enriched and made more contextually relevant. Ethical challenges surrounding data sovereignty, informed consent, cultural sensitivity, and the use of contested techniques are addressed, with recommendations for more equitable and transparent forensic practices. Policy reforms are proposed to institutionalise forensic odontology through education, infrastructure development, legal recognition, and collaborative networks. The article argues that decolonisation is not a rejection of global science but a reorientation toward context-appropriate, ethically grounded, and locally led forensic systems. Through these reforms, Sub-Saharan Africa can build a forensic odontology discipline that is scientifically robust, culturally responsive, and capable of delivering justice and dignity to affected communities.</div></div>","PeriodicalId":36925,"journal":{"name":"Forensic Science International: Synergy","volume":"11 ","pages":"Article 100622"},"PeriodicalIF":0.0,"publicationDate":"2025-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144522410","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}

A woman was found brutally murdered in her home with anatomical parts of the body found scattered in the kitchen and in the freezer of the house. A scene analysis, an autopsy and criminological investigations using the psychological autopsy method were carried out. Forensic investigations proved that the cohabiting son had killed the woman using a blunt instrument causing her a head trauma and had subsequently dismembered the corpse by carrying out necrocannibalism. The psychological autopsy revealed that the man suffered from severe schizophrenia not treated with drugs and that he had previously attempted to attack his mother on other occasions.

The results reveal significant differences in the establishment and management of these databases, reflecting diverse legal and operational contexts. The findings underscore the need to ensure that all European countries implement their elimination databases to standardize forensic procedures and improve the reliability of DNA evidence.

Recent technological developments including the use of AI and advanced computational forensic software have made possible forensic examinations and expert opinions that previously would have been impossible. Alongside benefits, the use in criminal trials of forensic evidence based on computational technologies such as Probabilistic Genotyping (PG) DNA, is posing difficult problems for courts and has been met with controversy. This study focuses on one important aspect of the criticism surrounding the use of PG DNA evidence, which relates to the probabilistic reporting of the forensic evidence results. It explores whether the use of likelihood ratios to report evaluative expert opinions infringes the presumption of innocence. This is a fundamental question that concerns not only evidence based on advanced computational technologies such as PG DNA but all forensic disciplines where the use of likelihood ratios and probabilistic assessments of the evidence are being actively promoted. This article argues that the criticism on the use of probabilistic methods for evidence evaluation encountered in legal practice, scholarly debate, policy and legal reform documents, is founded on misunderstandings of the role and limitations of the forensic evidence, of the processes involved in arriving at an evaluative expert opinion, as well as of the meaning and scope of the presumption of innocence itself. An enhanced understanding of these fundamental issues will lead towards a better regulation of AI and forensic algorithms across jurisdictions, without diminishing the impact of the scientific evidence in criminal proceedings and beyond.</div></div>","PeriodicalId":36925,"journal":{"name":"Forensic Science International: Synergy","volume":"11 ","pages":"Article 100591"},"PeriodicalIF":0.0,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144322316","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}

Three cadavers (donors) were placed at an outdoor human decomposition facility, and volatile organic compounds (VOCs) were collected and analyzed using thermal desorption coupled with comprehensive two-dimensional gas chromatography-time-of-flight mass spectrometry (TD-GC × GC-TOFMS). The key findings revealed that nitrogen-containing compounds were predominant in early post-mortem VOC profiles, driven by enzymatic and bacterial activity. Esters, alcohols, and halogenated compounds were also identified, with esters linked to microbial transformation and alcohols possibly formed by lipid peroxidation. Ante-mortem VOCs were persistent across samples, influenced by skin microbiota and environmental factors like UV radiation, complicating the detection of decomposition odor. Post-mortem VOCs became more prominent after ADD 73.4(experimental day 3), signaling the transition to the bloat stage of decomposition. Variations in sample collection methods and external factors such as temperature were found to affect VOC abundances. This study provides critical insights into odor transition and has implications for the use of search and rescue (SAR) and human remains detection (HRD) dogs. Further research is needed to standardize methods and assess odor transitions across diverse environments and seasons.</div></div>","PeriodicalId":36925,"journal":{"name":"Forensic Science International: Synergy","volume":"11 ","pages":"Article 100616"},"PeriodicalIF":0.0,"publicationDate":"2025-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144255505","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}
