The decomposition of a body, and the associated gaseous and liquid discharges emanating from it, attract gravid female blow flies which lay their eggs in or on the body. After the eggs have hatched, the emerging larvae start feeding on the body. As decomposition progresses, the blow fly larvae often migrate away, typically in a random manner in search of favourable conditions for pupation. In this paper, we report on a rarely described phenomenon of unidirectional mass migration of blow fly larvae and postulate on the factors which may drive this process. A decomposition trial utilising a 60-kg pig carcass, deployed in the summer months in Table Mountain National Park, Cape Town, South Africa, was conducted in 2022. On the fifth day of the trial, simultaneous unidirectional mass dispersal of blow fly larvae was observed. The larvae moved downhill in a southeasterly direction, following the flow of decomposition fluids oozing out from the pig carcass. The 'larval migration stream' had a length of approximately 1.5 m with a width of 40 cm, tapering to 17 cm at the terminal point. The larval migration stream consisted of the larvae of Chrysomya albiceps and Chrysomya chloropyga. This study demonstrates the importance of understanding the timing and pattern of dispersal of post-feeding blow fly larvae in each geographical region. This is crucial as the minimum post-mortem interval can be miscalculated if older immature insects dispersing from the corpse are not considered and collected during crime scene investigations. SIGNIFICANCE: • Understanding the timing and pattern of dispersal of blow fly larvae from decomposing vertebrate remains in each geographical region is important in time-since-death estimations when using entomological evidence. • In the summer season of the Western Cape Province, Chrysomya albiceps and Chrysomya chloropyga are among the blow fly species of forensic importance as they deposit their eggs on vertebrate remains. • When a decomposing body is found within the Table Mountain region, we suggest that crime scene investigators should examine the downhill area of the scene for larval/pupal entomological evidence that can assist in time and season of death estimations.

Resumen: El desempeño eficaz y oportuno de las funciones por parte de los agentes encargados del cumplimiento la ley bajo la ley marcial es un paso importante en el camino hacia el restablecimiento del orden público perturbado por el conflicto armado. El objetivo del estudio fue analizar la estructura del mecanismo de derecho administrativo que rige las actividades de los organismos encargados de hacer cumplir la ley bajo la ley marcial. El objeto de investigación de múltiples aspectos determinó el uso de una amplia gama de métodos, como el análisis comparativo y el método de derecho comparado. En ese sentido, la aplicación de medidas por parte de la policía para realizar un examen técnico forense del lugar de los hechos tras el descubrimiento de artefactos explosivos y municiones sospechosas se considera eficaz para garantizar el orden público durante la ley marcial. Durante un conflicto armado, los agentes del orden llevan a cabo sus actividades de conformidad con las disposiciones del derecho administrativo que rigen las actividades de aplicación de la ley bajo la ley marcial. Una estructura coordinada de los organismos encargados de hacer cumplir la ley durante la ley marcial ayuda a establecer la ley y el orden, y a respetar los derechos humanos y libertades. Investigaciones futuras sobre las actividades de los organismos encargados de hacer cumplir la ley bajo la ley marcial pueden centrarse en desarrollar recomendaciones prácticas sobre la eficacia de las actividades policiales, y estos pueden ser el desminado del territorio y la inspección del lugar por parte de la policía en caso de descubrimiento de artefactos explosivos.

Abstract: Effective and timely performance of duties by law enforcement officers under martial law is an important step on the way to restoring law and order disturbed by the armed conflict. The aim of the study was to analyze the structure of the mechanism of administrative law governing the activities of law enforcement agencies under martial law. The multiple- aspect research object determined the use of a wide range of methods, such as the comparative analysis and the method of comparative law. In this sense, implementing measures by the police to provide a technical forensic examination of the scene upon the discovery of suspicious explosive devices and ammunition is considered effective for ensuring law and order during martial law. During an armed conflict, the law enforcement officers carry out their activities in compliance with the provisions of administrative law governing law enforcement activities under martial law. A coordinated structure of law enforcement agencies during martial law helps to establish law and order and observe human rights and freedom. Further research on the activities of law enforcement agencies under martial law may focus on developing practical recommendations regarding the effectiveness of police activities, and these may be demining the territory and inspecting the scene by the police in the event of the discovery of explosive devices.

Abstract: The article seeks to provide evidence to the characterization of a long-standing process of social construction of disaster risk, in which risk-insensitive territorial planning is recognized as the main underlying risk drivers. Through a processual approach, we conclude about the close relationship between neoliberal urbanization processes and the multilevel deployment of business power, which mobilizes real estate developments that have promoted an environmentally predatory urban-tourist expansion for the area of interest and directly influenced in the exposure to disaster risk of residents and built infrastructure. Through the forensic investigation methodology that analyzes the underlying causes of disasters (FORIN), it is possible to deconstruct the situation currently experienced by a group of buildings located in the exclusive coastal residential sector of Cochoa, Reñaca Norte, Viña del Mar, Valparaíso Region Chile, which they have been categorized as uninhabitable due to two neighboring sinkholes that condition their stability and occupation since august 2023. Located on a fragile ecosystem such as a dune field, there were technical studies that accounted for the risk of overloading it with buildings, however, the recognition of risk was omitted in the respective territorial planning instrument —Communal Regulatory Plan of Viña del Mar— defining the location area as a residential zone.

Resumen: El artículo busca aportar evidencia a la caracterización de un proceso de construcción social del riesgo de desastres de larga data, en el cual la planificación territorial insensible al este se reconoce como el principal factor subyacente. Mediante un enfoque procesual se concluye sobre la estrecha relación existente en procesos de urbanización neoliberal y el despliegue multinivel del poder empresarial, el que moviliza desarrollos inmobiliarios que han promovido una expansión urbana-turística depredadora ambientalmente para la zona de interés e incidido directamente en la exposición a riesgo de desastres de los residentes y de la infraestructura construida. Mediante la metodología de investigación forense que analiza las causas de base de los desastres (Forensic Investigations of Disaster, FORIN), es posible deconstruir la situación que experimenta actualmente un conjunto de edificios ubicados en el exclusivo sector costero residencial de Cochoa, Reñaca norte, Viña del Mar, Región de Valparaíso en Chile, los que han sido categorizados como inhabitables debido a dos socavones aledaños que condicionan suestabilidad y ocupación desde el mes de agosto de 2023. Emplazados sobre un ecosistema frágil, como lo es un campo dunar, existieron estudios técnicos que daban cuenta del riesgo de sobrecargarlo con edificaciones, no obstante, se omitió el reconocimiento de riesgo en el respectivo instrumento de planificación territorial —Plan Regulador Comunal de Viña del Mar— definiendo el área de emplazamiento como zona residencial.

Three-dimensional (3D) anatomical extraction techniques could help the forensic anthropologist in a precise and inclusive assessment of biological phenotypes for the development of facial reconstruction methods. In this research, the nose morphology and the underlying hard tissue of two South African populations were studied. To this end, a 3D computer-assisted approach based on an automated landmarking workflow was used to generate relevant 3D anatomical components, and shape discrepancies were investigated using a data set of 200 cone-beam computer tomography (CBCT) scans. The anatomical landmarks were placed on the external nose and the mid-facial skeleton (the nasal bones, the anterior nasal aperture, the zygoma, and the maxilla). Shape differences related to population affinity, sex, age, and size were statistically evaluated and visualised using geometric morphometric methods. Population affinity, sexual dimorphism, age, and size affect the nasal complex morphology. Shape variation in the mid-facial region was significantly influenced by population affinity, emphasising that shape variability was specific to the two population groups, along with the expression of sexual dimorphism and the effect of ageing. In addition, nasal complex shape and correlations vary greatly between white and black South Africans, highlighting a need for reliable population-specific 3D statistical nose prediction algorithms. SIGNIFICANCE: • 3D anatomical structures were acquired and extracted from 200 CBCT scans of modern South Africans. • Geometric morphometric methods were applied. • Soft- and hard-tissue nasal complex morphology vary across South African groups.

Resumen Se discute la validez de la memoria disociativa en contextos forenses y las causas de las llamadas "guerras de la memoria". Conceptos erróneos entre la psicología clínica y la psicología forense, una definición deficiente de la amnesia y las dificultades inherentes en el estudio de recuerdos traumáticos contribuyen a la persistencia de esta controversia. Particularmente en el campo de la psicología forense, el debate podría atribuirse a la falta de consenso sobre la evidencia científica. Los psicólogos necesitan establecer una base empírica para comprender mejor los mecanismos de la memoria involucrados en recordar y olvidar recuerdos traumáticos. Se esboza el Modelo de Accesibilidad Continua de la Memoria para explicar la recuperación de los diferentes grados de accesibilidad a los recuerdos autobiográficos basados en diferentes factores.

Abstract The validity of dissociative memory in forensic contexts and the causes of the so-called "memory wars" are discussed. Misconceptions between clinical and forensic psychology, a deficient definition of amnesia, and the difficulties inherent in studying traumatic memories contribute to the persistence of this controversy. Particularly in the field of forensic psychology, the debate could be attributed to the lack of consensus on scientific evidence. Psychologists need to establish an empirical foundation to understand better the mechanisms of memory involved in remembering and forgetting traumatic memories. The Continuous Accessibility Model of Memory is outlined to explain the retrieval of the different degrees of accessibility to autobiographical memories based on different factors.

Resumen En Costa Rica, el Reglamento de la Autopsia Hospitalaria y Médico Legal establece que la autopsia médico legal es obligatoria para toda muerte súbita. La patología cardíaca es responsable aproximadamente del 80 % de las muertes súbitas que requieren una autopsia forense; el prolapso de la válvula mitral (degeneración mixomatosa de la válvula mitral) es una de las formas más comunes de valvulopatía cardíaca, es relativamente común (2%-3% de la población general), y a menudo se considera benigno, la tasa anual de muerte cardíaca súbita (MSC) en individuos con MVP (0,2%-0,4% /año) es aproximadamente el doble que el observado en la población general (0,1%-0,2% año).

Abstract In Costa Rica, the Hospital and Legal Autopsy Regulations establish that a legal medical autopsy is mandatory for all sudden deaths. Cardiac pathology is responsible for approximately 80% of sudden deaths requiring a forensic autopsy; Mitral valve prolapse (myxomatous mitral valve degeneration) is one of the most common forms of heart valve disease, is relatively common (2%-3% of the general population), and is often considered benign, the annual rate of Sudden cardiac death (SCD) in individuals with MVP (0.2%-0.4%/year) is approximately twice that observed in the general population (0.1%-0.2%/year).

Materials and methods: The analysis of the protocol of the medical-legal autopsy carried out, and a bibliographic review, were carried out. A 37-year-old female who apparently suffered from “sciatic nerve pain,” who died in her home after experiencing intense pain located in her back and dyspnea. After the medical-legal autopsy, acute chest syndrome due to sickle cell disease was established as the cause of death. Conclusions: Sickle cell anemia must be kept in mind at the time of the medical-legal evaluation as a possible cause of death, for this it is necessary to know the pathophysiology of this disease, and to be able to identify these effects when performing the Medical- Legal Autopsy, for this It is necessary to have all the possible tools to be able to make an accurate diagnosis.

On 6 September 1966, the prime minister of South Africa, Dr HF Verwoerd was killed by Mr Tsafendas, a Portuguese national of Greek descent, in parliament by stabbing him in the chest. Mr Tsafendas was a messenger in parliament. At the enquiry trial of Mr Tsafendas, he was found unfit to stand trial on the ground that he suffered from schizophrenia. The psychiatric evidence during the enquiry trial was reviewed and discussed under the following headings: Diagnosis of schizophrenia; Consideration of cultural factors in forensic psychiatric settings; Delusional infestation v. extreme overvalued beliefs; Simulation of psychosis; Ethical considerations in criminal capacity and trial competency assessments. Lessons from the Mr Tsafendas enquiry trial for forensic psychiatrists where a defendant previously diagnosed with schizophrenia commits a prominent political murder, are summarised. It is emphasised that the personhood of an accused referred for forensic observation should be respected and protected, instead of focusing exclusively on a specific diagnosis.

Resumen La entomotoxicología forense, que analiza insectos necrófagos para detectar sustancias tóxicas, es crucial en la determinación de causas de muerte y la estimación del intervalo post-mortem. Este estudio se centró en Peckia intermutans (Walker) (Diptera: Sarcophagidae) como marcador para la detección de metanol, un alcohol potencialmente letal presente como adulterante en bebidas alcohólicas debido a su bajo costo y parecido con el etanol. Se desarrolló un método de cromatografía de gases-espectrometría de masas (HS-GC-MS) para detectar metanol y se estudió su efecto sobre el tiempo de desarrollo, supervivencia y morfología de las moscas de la carne. Las larvas se criaron en sustratos de hígado enriquecidos con metanol (300, 500 y 1000 mg/kg). Los resultados mostraron: el método desarrollado detectó metanol en todos los estadios; el metanol afectó el tiempo de desarrollo de las moscas; la supervivencia aumentó con una mayor concentración de metanol; y los cambios morfológicos fueron evidentes en el peso. Este estudio ofrece valiosa información sobre la investigación entomotoxicológica del Ecuador, por lo que se debe considerar los cambios morfológicos de P. intermutans para evitar estimaciones inexactas de los intervalos post-mortem.

Abstract Forensic entomotoxicology, which analyzes necrophagous insects to detect toxic substances, is crucial in determining causes of death and estimating the post-mortem interval. This study focused on Peckia intermutans (Walker) (Diptera: Sarcophagidae) as a marker for detecting methanol, a potentially lethal alcohol often added as an adulterant in alcoholic beverages due to its low cost and similarity to ethanol. A gas chromatography-mass spectrometry (HS-GC-MS) method was developed to detect methanol, and its effects on the development time, survival, and morphology of flesh flies were investigated. Larvae were reared on liver substrates enriched with methanol (300, 500, and 1000 mg/kg). Results showed: the developed method detected methanol in all instars; methanol affected the developmental time of the flies; survival increased with higher methanol concentration; and morphological changes were evident in weight. This study provides valuable information on entomotoxicological research in Ecuador, emphasizing the need to consider morphological changes in P. intermutans to avoid inaccurate estimations of post-mortem intervals.

ABSTRACT Despite the numerous efforts of the international community to eradicate all forms of violence against women, this problem is far from being resolved. According to the UN, one in three women has suffered physical or sexual violence from an intimate partner, sexual violence outside the couple, or both at least once in their life. Addressing this problem as a social health need of population groups allows an approach to gender violence as a collective health problem. At the level of physical violence, strangulation/suffocation has been identified as one of the most lethal forms of domestic violence and sexual assault. Victims of domestic violence who have been choked or strangled are 7.5 times more likely to be killed by their partner. A victim of strangulation/suffocation can lose consciousness in seconds or die within minutes, days or weeks after the attack, as well as suffer permanent brain damage or disability or emotional trauma. Recently, legal changes have been generated in the configuration of this crime, the penalties have increased in United Kingdom, the United States, Australia and New Zealand. The current non-systematic narrative review of literature sought to explore updated medico-legal aspects of non-fatal strangulation/suffocation in the context of gender violence, and are highlightedrelevant implications for clinical practice.

RESUMEN A pesar de los numerosos esfuerzos de la comunidad internacional en pos de erradicar todas las formas de violencia contra las mujeres, esta problemática se encuentra lejos de ser resuelta. Según la ONU, una de cada tres mujeres ha sufrido violencia física o sexual por parte de la pareja, violencia sexual fuera de la pareja, o de ambas, al menos una vez en su vida. El abordaje de esta problemática, en tanto necesidad social de salud de grupos poblacionales, permite una aproximación a la violencia de género como un problema de salud colectiva. En el plano de la violencia física, la estrangulación/sofocación ha sido identificada como una de las formas más letales de violencia doméstica y agresión sexual; se ha reportado que una víctima que es estrangulada una primera vez tiene 7,5 más probabilidades de ser asesinada posteriormente por el mismo abusador. Una víctima de estrangulación/sofocación puede perder la conciencia en segundos o morir en minutos, días o semanas después del ataque o sufrir daño cerebral permanente o invalidez, además del trauma emocional. Recientemente, se han generado cambios legales en la configuración de este delito; las penas han aumentado en el Reino Unido, Estados Unidos, Australia y Nueva Zelandia. El propósito de esta revisión de literatura de tipo narrativo, no sistemática, está orientada a presentar aspectos médico-legales actualizados de la estrangulación/sofocación no fatal en el contexto de la violencia de género, y se resaltan aquellas implicancias relevantes para la práctica clínica.

As one of the most important types of evidence at the scene of the crime, the rapid identification of the human bloodstain is of great significance to solve the criminal case. In this paper, the spectral data of different species of bloodstain samples including human, chicken and pig were acquired by using a hand-held near-infrared spectrometer. Then, the training models were established via convolutional neural network-support vector machine algorithm. Meanwhile, the traditional support vector machine, genetic algorithm-back propagation and random forest classification algorithms were also compared. The results showed that the prediction accuracy of convolutional neural network-support vector machine algorithm was the highest and the overall performance of the model was the best. The rapid detection method based on a handheld near-infrared spectrometer and convolutional neural network-support vector machine algorithm could identify the species of bloodstain efficiently, non-destructively, quickly and accurately and it provided a new technical reference for bloodstains detection and identification. crime case paper hand held nearinfrared near infrared Then networksupport network Meanwhile algorithmback back compared best efficiently nondestructively, nondestructively non destructively, destructively non-destructively

Abstract In the modern world, cancer is a growing cause of mortality, but archeological studies have shown that it is not exclusive to modern populations. The aim of this study is to examine the epidemiologic, social, and clinicopathologic features of head and neck cancers in ancient populations. To do this, we extracted all records that described malignant lesions in the head and neck region available in the Cancer Research in Ancient Bodies Database (CRAB). The estimated age, sex, physical condition of the remains (skeletonized, mummified), anatomic location of tumors, geographic location, chronology, tumor type, and methods of tumor diagnosis were collected. One hundred and sixty-seven cases were found, mostly originating from Europe (51.5%). Most records were of adults between 35 and 49 years of age (37.7%). The most involved site was the skullcap (60.4%), and the most common malignancies were metastases to the bone (65.3%) and multiple myeloma (17.4%). No primary soft tissue malignancies were registered. The results of our study indicate that head and neck cancers were present in ancient civilizations, at least since 500,000 BCE. The available data can help to improve the current understanding of the global distribution of head and neck cancer and its multidimensional impacts on populations in the contemporary world. world mortality epidemiologic social CRAB.

Abstract Recent decades have witnessed the development and expansion of the uses of science and technology in many areas of social life. For criminal justice, this expansion can constitute an opportunity to incorporate and test the power of the new forensic tools. However, being traditional institutions, police forces, and the justice system in general, can go through adaptation periods where novel tools are incorporated into existing ways of thinking and doing. Through focus groups carried out in Forensic Technical Police Units (UPT) in Portugal and adopting qualitative and interpretative methodologies, this paper seeks to understand how DNA technology is incorporated into investigative police work. In doing so it explores the “reflection in action” done by the UPTs and the “troublesome knowledge” associated with their work: tacit, inert, ritual, alien and also a new type of knowledge that we call here illusory knowledge. life However institutions forces general UPT (UPT methodologies work reflection action troublesome tacit inert ritual

Resumo As últimas décadas têm testemunhado o desenvolvimento e a expansão dos usos da ciência e da tecnologia em muitas áreas da vida social. Para a justiça criminal essa expansão pode constituir uma oportunidade para incorporar e testar o poder das novas ferramentas forenses. Contudo, tratando-se de instituições tradicionais, as forças policiais e o sistema de justiça em geral podem necessitar de períodos de adaptação para que as novas tecnologias sejam incorporadas nas maneiras de pensar e de fazer. Com base em grupos focais realizados em Unidades de Polícia Técnica Forense (UPT) em Portugal e adotando metodologias qualitativas e interpretativas, este artigo procura perceber como é que as tecnologias de ADN são incorporadas no trabalho de investigação policial. Ao fazê-lo explora a “reflexão na ação” feita pelas UPT e o “conhecimento problemático” associado ao seu trabalho: conhecimento tácito, inerte, ritual, alien e ainda um novo tipo de conhecimento a que aqui chamamos de ilusório. social forenses Contudo tratandose tratando se tradicionais fazer (UPT interpretativas policial fazêlo fazê lo reflexão ação problemático tácito inerte ritual ilusório

Objective: to analyze nurses’ role in collecting, identifying and preserving traces in Emergency care for victims of violence, from the perspective of these professionals. Method: a qualitative study with an exploratory and descriptive approach. It was developed through semi-structured interviews with 21 nurses from hospitals that are part of the intersectoral flow to assist victims of violence from two reference hospitals in this type of care, in a capital city from southern Brazil. Nurses that are members of the multiprofessional team working in the Emergency areas at the respective hospitals were included; in turn, the exclusion criteria corresponded to professionals relocated in Emergency areas during the pandemic. Data analysis was performed according to Thematic Content Analysis. Results: the data were discussed in five categories: 1) Professional qualification; 2) Institutional protocol and materials; 3) The professionals’ perceptions; 4) The professionals’ actions; and 5) Team structure. Conclusion: Nursing professionals’ skills in collecting, identifying and preserving traces in Emergency assistance provided to victims of violence need to be better organized, structured and standardized. The presence of Nursing professionals in the care of victims of violence in Emergency services is undeniable, but their importance is still underestimated and their potential contribution to the forensic approach is underused.
