Abstract The detection of burned human remains in a fire is daunting, mainly when identifiable skeletons are not found. This study aims to identify volatile organic compounds (VOC) released from the burning of porcine bones in the presence of diesel in a simulated controlled outdoor setting in Malaysia. Neat diesel was diluted with hexane with a ratio of 1:1 and administered into a gas chromatography-mass spectrometry (GC-MS). Porcine bone was burned to identify VOCs of porcine bones, whereas 30 mL diesel was burned together with porcine bones to identify VOCs produced from the combined burning. After the burning process, an activated carbon tablet was fixed to the burned sample. Later, the tablet was desorbed with hexane and analysed using GC-MS. Results revealed that the combined burning released a set of VOCs that were not detected in burned porcine bone or neat diesel. This work was able to enforce the detection of specific volatiles from various functional groups such as alkanes, isoalkanes, alkylbenzenes and ketones in the combined burning of diesel with porcine bones. It was also discovered that in the specific conditions applied and controlled in this study, most VOCs of porcine bone and diesel respectively were not detected in the combined burning of porcine bone and diesel. Résumé La détection de restes humains brûlés lors d’un incendie est une tâche ardue, surtout lorsque des squelettes identifiables ne sont pas retrouvés. Cette étude vise à identifier les composés organiques volatils (COV) libérés par la combustion d’os de porc en présence de diesel dans un environnement extérieur contrôlé simulé en Malaisie. Le diesel pur a été dilué avec de l’hexane dans un rapport de 1:1 et introduit dans un chromatographe en phase gazeuse avec spectrométrie de masse (GC-MS). Des os de porc ont été brûlés pour identifier les COV, tandis que 30 ml de diesel ont été brûlés en même temps que les os de porc afin d’identifier les COV produits par la combustion combinée. Après le processus de combustion, une pastille de charbon actif a été fixée sur l’échantillon brûlé. La tablette a ensuite été désorbée avec de l’hexane et analysée par GC-MS. Les résultats ont révélé que la combustion combinée libérait une série de COV qui n’ont pas été détectés dans l’os de porc brûlé ou dans le diesel pur. Ce travail a permis de confirmer la détection de substances volatiles spécifiques provenant de divers groupes fonctionnels tels que les alcanes, les isoalcanes, les alkylbenzènes et les cétones dans la combustion combinée de diesel et d’os de porc. Il a également été découvert que dans les conditions spécifiques appliquées et contrôlées dans cette étude, la plupart des COV de l’os de porc et du diesel n’ont pas été détectés dans la combustion combinée d’os de porc et de diesel.

Abstract When a bullet strikes a surface such as a drywall panel, it may perforate the material leaving a hole in the surface or it may ricochet. When multiple bullet impacts exist, for example through a wall section, the probing method allows for the trajectory of a projectile to be reconstructed. Past studies have shown that low angle impacts are subject to error when applying the probing method. Hence, this study used the probing method to examine bullet impacts in wall sections made of drywall to determine the accuracy of the angle of incidence with respect to a known firing position. To control the angle of incidence, drywall panels were positioned at different angles beginning at 90° and decreasing until the panels were at 10°. The measured angle of incidence was compared to the known angle of incidence to determine the accuracy/error. The study observed how .40 S&W caliber ammunition from four different manufacturers, interacted with drywall panels. For each ammunition type and known angle there were three replicates, for a total of 84 impacts (n = 84). It was observed that as the angle of incidence decreased, the error of the measured value increased. Measurements from panel positions at higher angles (between 60°–90°) were more accurate and precise than measurements from panels positioned at lower angles of incidence (10°–45°). The data collected in this study provides insight into the probing method and how the accuracy of measurements can be impacted while the angle of incidence decreases. Résumé Lorsqu’un projectile entre en contact avec une surface, tel qu’un panneau de cloison sèche, il peut perforer le matériau et créer un orifice dans la surface ou encore il peut ricocher. Lorsqu’il y a plusieurs impacts de projectiles, par exemple sur une section de mur, l’emploi de tiges de trajectoire permet de reconstruire la trajectoire d’un projectile. Cependant, des études antérieures ont démontré que la mesure des impacts à angle faible est sujet à des erreurs d’exactitude lors de l’utilisation de cette méthode. Par conséquent, cette étude a utilisé des tiges de trajectoires pour analyser des impacts de projectile sur des sections de mur faites de cloisons sèches, afin de déterminer l’exactitude de l’angle d’incidence mesuré par rapport à une position de tir connue. Afin de contrôler l’angle d’incidence, des panneaux de cloison sèche ont été positionnés à différents angles, en commençant par 90° et en diminuant jusqu’à ce que les panneaux soient à 10°. L’angle d’incidence mesuré a été comparé à l’angle d’incidence connu afin de déterminer l’exactitude/erreur de cette méthode. Cette étude a permis d’observer l’interaction entre les munitions de calibre .40 S&W de quatre fabricants différents et les panneaux de cloisons sèches. Pour chaque type de munition et chaque angle connu, trois réplicas ont été effectués, pour un total de 84 impacts (n=84). Il a été observé que plus l’angle d’incidence diminuait, plus l’erreur de la valeur mesurée aug

Abstract The search for the truth can be a daunting task, but without knowing what happened and who is responsible, there can be no attempt at achieving any measure of justice. Forensic scientists often play a pivotal role in determining significant facts and interpreting those facts for the court to consider. When called to testify, expert witnesses have a special duty to the court to provide fair, objective, and non-partisan assistance. The courtroom becomes the classroom as the expert witness takes on pedagogical duties of teaching the underlying science, methodology, and the nuances of forensic opinions. Depending on the area of expertise and evidence, the learning curve for the trier of fact can be steep. The didactic presentation of complex data requires planning and skill. Drawing upon my Courtroom Testimony for Expert Witnesses course and my PhD research, I focus on the search for truth, expert witness bias, and the challenge of teaching complex science to the trier of fact. There will be specific emphasis on the incorporation of visual evidence to explain complex concepts in a more concise and memorable manner to aid in comprehension. The expert witness is a teacher and how the expert teaches makes a difference. Résumé La recherche de la vérité peut être une tâche intimidante, mais sans savoir ce qui s’est passé ou qui est responsable, il ne peut y avoir de tentative à atteindre une certaine justice.

Lorsqu’ils sont appelés à témoigner, les témoins experts ont un devoir particulier envers la cour de fournir une assistance équitable, objective et sans parti pris. La salle d’audience devient la salle de classe alors que le témoin expert assume les tâches pédagogiques en enseignant la science fondamentale, la méthodologie et les nuances des opinions judiciaires.

Abstract The importance of well-preserved knots and ligatures, in conjunction with clear and unambiguous photographs and other recording techniques, is demonstrated using comparatively flawed and idealized images of mock exhibits. The identification of wends (working ends), stands (standing parts), severed ends, and unobstructed crossing points is critical. Further, determining the lengths of segments and the circumferences of loops, along with rope or cord diameters, can be of assistance during an analysis. Subtle details, such as the interrelationship of various wraps and complex entanglements, can be maintained when employing careful removal procedures. Any information that might be acquired from the knotted evidence could inform subsequent determinations and conclusions. Carefully preserved exhibits and recorded details may assist the analyser of knots and ligatures in establishing the tying sequence, the purpose of those knots, the tying habits and relative skill level displayed, and possibly the number of tiers. Case-specific issues, such as whether the knotted evidence points to homicide or suicide, may be clarified.
摘要:保存完好的结和结扎的重要性,结合清晰和明确的照片和其他记录技术,用比较有缺陷和理想化的模拟展品的图像来证明。确定断头(工作端)、断头(站立部分)、断头和畅通无阻的交叉点至关重要。此外,确定分段的长度和环的周长,以及绳索或绳索的直径,可以在分析过程中提供帮助。细微的细节,如各种包裹和复杂纠缠的相互关系,可以在采用仔细的去除程序时保持不变。从纠缠的证据中可能获得的任何信息都可以为随后的确定和结论提供信息。仔细保存的展品和记录的细节可以帮助结和结扎分析人员确定打结顺序、这些结的目的、打结习惯和所显示的相对技能水平,以及可能的层数。具体案件的问题,例如这些纠缠不清的证据是指向他杀还是自杀,可能会得到澄清。

Abstract Drowning is the third leading cause of accidental death globally, however, many individuals who lose their lives at sea are never recovered or identified. Along with the geographic challenges posed by the underwater environment, environmental conditions influence the degradation and preservation of submerged remains. Understanding how human bodies decompose in the marine environment can assist with more accurate estimations of the postmortem submersion interval, reconstruction of the postmortem history, and determination of the original deposition environment, as well as prepare recovery teams and their families for what to expect upon locating the deceased in a marine environment. In this review, previous research surrounding human remains in the marine environment is reviewed with a focus on the factors that will influence decomposition of the human body from initial submergence to skeletonization. Experimental research, retrospective analyses, and case studies are brought together in this paper to demonstrate the currently available knowledge on marine decomposition. It is suggested that further systematic research is necessary to create robust evidentiary standards to develop context-specific knowledge on which to base future forensic investigations and assist with the recovery and identification of submerged individuals.
摘要溺水是全球意外死亡的第三大原因,然而,许多在海上丧生的人从未康复或确认身份。除了水下环境带来的地理挑战外,环境条件也影响着水下遗迹的退化和保存。了解人体是如何在海洋环境中分解的,有助于更准确地估计死后浸入时间间隔、重建死后历史和确定原始沉积环境,并为恢复团队及其家人做好准备,以便在海洋环境下找到死者。在这篇综述中,回顾了以往关于海洋环境中人类遗骸的研究,重点是从最初的潜水到骨骼化,影响人体分解的因素。本文将实验研究、回顾性分析和案例研究结合在一起,以展示目前关于海洋分解的可用知识。有人建议,有必要进行进一步的系统研究,以制定强有力的证据标准,发展针对具体情况的知识,为未来的法医调查奠定基础,并协助打捞和识别被淹没的个人。

Abstract Computer-generated models have revolutionized how reconstructions of violent events, such as police use of force, are both performed and visualized. Yet, many experts in the legal and forensic disciplines do not understand them at a level required to use them effectively or create credible arguments supporting their findings. Simply put, models are a simplification of reality. Hence, models permit human programmers to specify the simplified behavior of a system. Since model parameters dictate the system's behavior, the programmer must document and provide justification for the selection of model parameters. The model structure, together with the selected parameters, form the backbone supporting the forensic investigator’s conclusions. This paper will begin with an overview of the usefulness of models in forensic investigations and follow with an example of how a model is constructed and applied in use of force cases. The selected cases are particularly relevant to incidents commonly encountered in law enforcement, frequently leading to litigation.
计算机生成的模型已经彻底改变了暴力事件(如警察使用武力)的重建方式和可视化方式。然而,法律和法医学科的许多专家对它们的了解程度不足以有效地使用它们或提出支持其发现的可信论点。简单地说,模型是对现实的简化。因此,模型允许人类程序员指定系统的简化行为。因为模型参数决定了系统的行为,所以程序员必须记录并提供模型参数选择的理由。模型结构与所选择的参数一起构成了支持法医调查员结论的支柱。本文将首先概述模型在法医调查中的有用性,然后举例说明如何构建模型并将其应用于使用武力的案件。所选个案与执法中经常遇到的事件特别相关,经常导致诉讼。

Abstract The third trochanter (TT) is a proximal femoral accessory tubercle at the upper border of the gluteal tuberosity that is unusually encountered on the posterior aspect. However, detailed knowledge about the TT remains limited. For this reason, TT was investigated in all its aspects. To give an overview about the TT, a review was conducted in databases until November 2021. Out of 4981 articles, only 53 articles could be included, most of which were studies conducted on dry femurs. The TT can be a result of the developmental process of gluteus maximus due to posture and bipedal locomotor activity. Another explanation of the formation of TT is the inactivation, deficiency, or mutation of specific genes that cause alterations in the proximal femoral end. The current review leads to the assumption that TT, considered for all mammalians, can be an evolutionary adaptation and may be a result of altered muscle activity, increased mechanical force, and reduced stress on the femoral shaft. Therefore, TT should be used in genomic studies related to the evolution of mammalians. An improvement in study design, the scale of the study, methodology, and the selection of mammalian species may permit more comprehensive analysis and reduce study heterogeneity. Résumé Le troisième trochanter (TT) du femur est un tubercule accessoire proximal au bord supérieur de la tubérosité fessière qui est exceptionnellement rencontré sur la face postérieure. Pour cette raison, le TT a été étudié avec tous ses characteristiques. Cependant, les connaissances détaillées sur le TT restent limitées. Pour cette raison, le TT a été étudié avec une approche exhaustive. Pour donner un aperçu sur le TT, une revue a été menée dans les bases de données jusqu’en novembre 2021. Sur 4981 articles, seuls 53 articles ont pu être inclus, dont la plupart étaient des études menées sur des fémurs secs. Le TT peut être le résultat du processus de développement du grand fessier en raison de la posture et de l’activité locomotrice bipède. Une autre explication de la formation du TT est l’inactivation, la déficience ou la mutation de gènes spécifiques qui provoquent des altérations de l’extrémité fémorale proximale. L’examen actuel conduit à l’hypothèse que le TT, considéré pour tous les mammifères, peut être une adaptation évolutive et peut être le résultat d’une activité musculaire altérée, d’une force mécanique accrue et d’un stress réduit sur la tige fémorale. Par conséquent, le TT devrait être utilisé dans les études génomiques liées à l’évolution des mammifères. Une amélioration de la conception de l’étude, de l’échelle de l’étude, de la méthodologie et de la sélection des espèces de mammifères peut permettre une analyse plus complète et réduire l’hétérogénéité de l’étude.
摘要第三粗隆(TT)是位于臀粗隆上缘的股骨近端副结节,在臀后侧少见。然而,关于TT的详细知识仍然有限。因此,对TT进行了全方位的研究。为了对TT进行概述,在数据库中进行了一次审查,直到2021年11月。在4981篇文章中,只有53篇文章可以被纳入,其中大部分是对干股骨的研究。TT可能是臀大肌发育过程中姿势和双足运动活动的结果。TT形成的另一种解释是导致股骨近端改变的特定基因失活、缺乏或突变。目前的综述认为,考虑到所有哺乳动物,TT可能是一种进化适应,可能是肌肉活动改变、机械力增加和股轴应力减少的结果。因此,TT应该用于与哺乳动物进化相关的基因组研究。研究设计、研究规模、方法和哺乳动物物种选择方面的改进可能允许更全面的分析并减少研究的异质性。rs - 331 - 331 - 331 - 331 - 331 - 331 - 331 - 331 - 331 - 331 - 331 - 331 - 331 - 331 - 331 - 331 - 331 - 331 - 331 - 331 - 331 - 331 - 331出于同样的原因,我们认为,TT是一种具有不同特征的个体。独立的,不允许有任何的限制,例如,不允许有任何的限制。倒这个雷森,le TT的疾病我们用一个approche详尽。从2021年11月开始,我们将对所有的薪金和薪金进行评估,并对薪金和薪金进行评估。共有4981篇文章,其中53篇文章包括:être,不包括:部分的samient,部分的samient,部分的samient,部分的samient,部分的samient。在这一过程中,我们将会看到:在这一过程中,我们将会看到:在这一过程中,我们将看到:在这一过程中,我们将看到:一个真正的解释是,关于变性的形成,关于变性的变异,关于变性的变异,关于变性的变异,关于变性的变异,关于变性的变异,关于变性的变异,关于变性的变异。L 'examen actuel conduit ' L ' hypoth se que le TT,考虑到 one adaptation(适应), one adaptation(适应),être(适应),(适应),(活动),(肌肉),(适应),(力量),(积累),(压力),(压力),(压力),(压力),(压力),(压力),(压力)。与此同时,我们也要考虑到,电子交换与电子交换与电子交换与电子交换与电子交换与电子交换。1 .从概念上看,从概念上看,从概念上看,从概念上看,从概念上看,从概念上看,从概念上看,从概念上看,从概念上看,从概念上看,从概念上看,从概念上看,从概念上看,从概念上看,从概念上看,从概念上看,从概念上看,从概念上看,从概念上看,从概念上看,从概念上看,从概念上看,从概念上看。

Abstract Since the onset of COVID-19, expert witness testimony has been delivered virtually in judge-alone trials in Ontario with increasing frequency. It is unknown how controllable technological factors in the virtual environment – such as camera angle – may influence jury perception of expert witness credibility. This study assesses whether camera angle has a significant effect on juror perception of expert witness credibility. Jury-eligible participants from Ontario (n = 72) acted as mock jurors in four mock drug trafficking trials involving the same virtual forensic toxicology testimony. The control group (n = 34) watched an expert who was shown from the mid-chest up, whereas the experimental group (n = 38) watched an expert who had their camera angle set to show only their head. Using the Witness Credibility Scale (WCS), participants assessed expert credibility by completing 20 Likert-scale questions related to the expert’s knowledge, likeability, trustworthiness, and confidence. A Mann-Whitney U test indicated no significant difference between the control and experimental groups (p = 0.66, p > 0.05). Therefore, camera angle has no significant impact on juror perception of expert witness credibility, suggesting that experts can use either angle when testifying virtually. This research may help to inform future best practices for virtual expert testimony, enhancing quality and standardization.
自2019冠状病毒病(COVID-19)爆发以来,安大略省几乎在法官单独审判中提供专家证人证词的频率越来越高。目前尚不清楚虚拟环境中的可控技术因素(如摄像机角度)如何影响陪审团对专家证人可信度的看法。本研究评估了镜头角度是否对陪审员对专家证人可信度的认知有显著影响。来自安大略省的符合陪审员资格的参与者(n = 72)在涉及相同虚拟法医毒理学证词的四个模拟贩毒审判中担任模拟陪审员。对照组(n = 34)观看了一位专家胸部中部以上的镜头,而实验组(n = 38)观看了一位专家的镜头角度只显示头部的镜头。使用证人可信度量表(WCS),参与者通过完成20个李克特量表问题来评估专家的可信度,这些问题与专家的知识、受欢迎程度、可信度和信心有关。Mann-Whitney U检验显示对照组与实验组之间无显著差异(p = 0.66, p > 0.05)。因此,镜头角度对陪审员对专家证人可信度的感知没有显著影响,这表明专家在虚拟作证时可以选择任意一个角度。这项研究可能有助于为未来虚拟专家证词的最佳实践提供信息,提高质量和标准化。

Abstract Age estimation methods based on dental radiographs are of the most accurate and popular methods for age estimation. The accuracy of these methods might vary between different ethnic groups. Therefore, the present study was performed in order to evaluate and update the Cameriere dental age estimation method in a population of Iranian children and compare it with the Willems dental age estimation method. A retrospective cross-sectional study was performed, using dental records and digital dental panoramic radiographs of 110 six- to 12-year-old patients (55 girls and 55 boys). In order to assess the accuracy of both methods, the difference between the estimated dental age and the Chronological age was calculated and compared. Results of the present study showed Willems method overestimated the age and the updated Iranian Cameriere method underestimated the age, but the over/underestimations were not significant, except for the boys in Willems group. Both Willems dental age estimation (WDA) and Iranian Cameriere dental age estimation (ICDA) methods were applicable in the selected population of Iranian children, although the WDA estimations were less accurate, especially for boys.
摘要基于牙片的年龄估计方法是最准确、最流行的年龄估计法。这些方法的准确性可能因种族而异。因此,本研究旨在评估和更新伊朗儿童群体中的Cameriere牙科年龄估计方法,并将其与Willems牙科年龄评估方法进行比较。对110名6至12岁的患者(55名女孩和55名男孩)进行了一项回顾性横断面研究,使用牙科记录和数字牙科全景照片。为了评估这两种方法的准确性,计算并比较了估计的牙齿年龄和按时间顺序排列的年龄之间的差异。本研究结果显示,Willems方法高估了年龄,而更新的伊朗Camerier方法低估了年龄,但高估/低估并不显著,Willemss组的男孩除外。Willems牙科年龄估计(WDA)和Iranian Cameriere牙科年龄评估(ICDA)方法均适用于选定的伊朗儿童群体,尽管WDA估计不太准确,尤其是对男孩。
