Forensic Anthropology in the identification of human remains found at sea: History of two judicial cases connected by the same marine context of discovery.

Background: Calculating the immersion time at sea of human skeletal remains is a challenge for forensic investigations and the answer to this question would solve many court cases in the shortest possible time. Remains in water create profound structural changes due to countless variables that lead to difficulties in interpretation during investigations. Case report: In this paper, two forensic cases found at sea were analysed, Case A, an extensively skeletonised corpse, and Case B, an isolated, intact foot with soft tissue, both found only 9 km away from the shores of the Tyrrhenian Sea (Southern Italy). A preliminary radiodiagnostic examination was performed for both cases. Subsequently, macroscopic observation of two tattoos found on case A was carried out. Autopsy examination was then carried out with subsequent anthropometric analysis to reconstruct the biological profile of both subjects, (case A) and (case B). Finally, histological and genetic analyses were performed. Conclusions: The examinations carried out made it possible to determine two compatible biological profiles, despite the taphonomic difference, and these examinations were corroborated by the anthropometric and genetic correlation, which led to the solution of a single judicial case. In conclusion, all the investigations carried out made it possible to state that the skeletonised corpse (Case A) and the isolated foot (Case B) belonged to the same individual in life. This result made it possible to identify the victim, thus establishing the profile of an individual who had disappeared in the previous two months due to a shipwreck.

Investigation on physical restraint use in hospital: health responsibility, ethical and medical legal considerations.

Background: The issue of restraint has long been considered a difficult political and social situation, affecting both healthcare wor-kers and facilities. The practice of restraint is still widespread in many public and private care settings, but there is a lack of systemic studies capable of monitoring the phenomenon. The framing of the question essentially concerns the right to personal freedom, guaranteed by the Italian Constitution. Materials and Methods: An anonymous questionnaire was developed containing questions on knowledge of the regulations on restraints, how, ways, and when they are implemented, and general information such as age, gender, educational qualification, qualification, O.Us. to which they belong. The collected data were statistically processed (Chi-square test) with the Epi Info 7.1.5 program (CDC-Atlanta- USA). A total of 1002 questionnaires were completed. The stratification of the sample by structure shows that 73.9% were public facilities. The indicative figure is represented by the 23.8% of respondents who say that "the restraint is not noted in the medical record". Conclusions: Restraint could be a real risk for the healthcare worker, encroaching on the issue of health liability. It is therefore important to raise awareness among healthcare professionals and top management of the need to structure, at company level, procedures that comply with the "Recommendations on physical restraint" to overcome the use of restraint through the improvement of care pathways in compliance with organizational and risk management standards.

A case of suicide of psychiatric patient in the Sicilian hospital: accidental or professional liability of "top management"?

Background: In the hospital environment, any liability for organizational inadequacy and/or inefficiency, or again for defects in the facilities, or inadequacy of health equipment may be found in the work of the apex professional figures: Medical Director, the General Manager, and/or others. The responsibility for the internal organization of the department falls on the figure of the Director of the Complex Structure where the deficiencies have not been promptly and adequately reported to the top figures. Case Report: A woman 61-year-old, was admitted on a voluntary basis to the Department of Psychiatry. On the third day, in the early morning hours, the patient was found on the ground floor, lying on the floor near the entrance door of the ward with a lacerated contusion wound to the head. The woman underwent total body CT examination with findings of fractured polytrauma as well as subarachnoid hemorrhage and complete fracture of the spleen, which was surgically removed. Three days later, despite the care given, death occurred. The injuries ascertained were consistent with voluntary precipitation from the second-floor stairwell window. The investigations conducted by the police and the checks carried out by the head of the Internal Prevention and Protection Service and the company's Risk Manager, highlighted multiple critical issues. Conclusion: The case allows for numerous considerations relating to liability profiles in the determinism of the patient's death, the hospital's company failure to implement measures to prevent the patient's suicide in the hospital was influential.

The study of the microbiome in forensic investigations on pediatric deaths.

Background: Sudden infant death syndrome (SIDS) is a tragic and devastating condition whose causes remain largely unknown. Recent studies have shown that the composition of a child's gut flora can play a significant role in the development of SIDS. Methods: This work aims to research those factors that influence the composition of the intestinal flora, the role they have in the development of SIDS and the new strategies for preventing SIDS showing a new interpretation through a detailed review of the literature. The gut in physiological conditions is mainly composed of Bacteroidetes, Firmicutes, Actinobacteria, and Proteobacteria, but when there is the presence of dysbiotic or different microbial communities, the onset of the disease is more likely as an altered microbial community can lead to an interruption of the gut-brain axis and an increased risk of SIDS. Conclusions: All this implies that the composition of the microbiome can be modified to reduce the risk of sudden death in newborns. The results of the literature provide valuable information on the potential role of the intestinal microbiome in SIDS even if not all mechanisms are yet clear, especially in the mechanisms of death. Therefore, it is necessary in cases of SIDS when carrying out an autopsy to also investigate this area; to this end, we suggest a questionnaire to be administered to family members to understand the eating habits of the newborn and the family and integrate with microbiological investigations to explore every possible hypothesis.

A rare case of maternal foetal death caused by uterine rupture in the placenta accreta.

Background: Fetal death has various causes, among the most common are problems relating to the placenta, such as placental abruption or placental malformations such as placenta accreta. From the literature, it emerges that placental analysis at autopsy can allow for greater resolution of cases compared to clinical history and external examination of the fetus alone. Case Report: We report the case of a woman at the eleventh week of pregnancy who died in hospital. The medical history revealed two further previous pregnancies, both with births by cesarean section. The autopsy identified the cause of maternal death as acute cardiorespiratory arrest secondary to hemorrhagic shock from spontaneous uterine rupture. Hemorrhagic infiltrate was found in the intervillous placental spaces with rupture of the uterus due to placenta previa and accreta. Discussion: Placenta accreta is a condition in which a pathological adherence and/or invasion of the myometrium by the placenta is observed. This condition poses a problem during recovery with potential for severe bleeding. Therefore, we emphasize the macroscopic and histological analysis of the placenta, uterus and the ovaries in all cases of maternal-fetal death, suggesting however that the organs be analyzed both by gross analysis and after permanence in formaldehyde. Furthermore, in these cases, it is important to evaluate the clinical history and data, especially ultrasound scans performed in life, or insertion anomalies during instrumental investigations. For this reason, we recommend to collaborate with a multidisciplinary team in these cases, including the gynecologist and the forensic pathologist.

Asphyxia with a blunt instrument: which forensic evidence to use in complex cases of murder.

Background: The blunt injuries may be heterogeneous. Due to the diversity, it is often difficult to establish the type of weapon used. Particular attention must be paid to the circumstantial data and previous diseases because the injuries often could not correspond to the presumed instruments used. Case Report: A man was found dead in his bedroom wearing pajamas. On the bed there was a blanket with visible traces of blood, which had dried. There were around 10 dogs in the house, poor hygienic and sanitary conditions, widespread excrements and unbreathable air. Testimonies from general practitioner, neighbors and the partner were collected. An autopsy, histological and toxicological examination was performed. On external examination the face showed blood smearing down the nose, subconjunctival hemorrhages, and labial cyanosis. Mo-reover, a hypochromic skin area was present on the right lateral region of the neck. The inguinal region showed large de-epithelized areas with multiple purplish red ecchymoses which were histologically analyzed. These areas showed hemorrhagic infiltration in the superficial and deep dermis up to the adipose tissue due to traumatic action. Conclusion: The reconstruction of the case allowed us to state a strangulation probably attributable to a belt. The discovery of intradermal hemorrhagic infiltrations, supported by histopathological investigations, confirmed the diagnosis of blunt force injuries, excluding other type of non-violent causes of lesions. Therefore, we recommended the use of experimental methods and procedures to evaluate the harmful suitability on biological matrices.

The role of necroscopy and autopsy investigations in the diagno-sis and risk management of infections related to public health care: forensic and medico legal implications.

Background: Healthcare-associated infections (HAIs) represent the most frequent adverse event in healthcare systems around the world. From a forensic point of view, HAIs show various legal implications. Therefore, it is essential in cases of death or injury from a suspected nosocomial infection that the infection itself, the source and the method of contamination are correctly diagnosed in order to evaluate any profiles of professional liability. Methods: This study combined a minireview of the scientific literature using the Pubmed search engine, the website of the Higher Institute of Health and the member states information sessions on infection prevention and control (IPC). Discussion: Despite the significant impact that HAIs have on healthcare systems, their severity is often not fully understood by healthcare professionals, leading to insufficient responses. In the autopsy setting, the diagnosis of these infections is not always simple due to the risk of post-mortem contamination determined by the endogenous bacterial flora. In the forensic field, the medical examiner during the autopsy can use various diagnostic techniques and investigative tools to identify the infection. Some usefulpp approaches include: 1) Macroscopic examination of the organs; 2) Histopathological investiga-tions; 3) Microbiological analyzes with the performance of swabs; 4) Immunofluorescence tests for the detection of antigens or antibodies on biological liquids; 5) Molecular tests. The choice of methods will depend on the nature of the suspected infection and the availability of diagnostic resources.

The experimental reconstruction of a complicated case of work accident due to a scraper.

Background: Workplace safety is a global public health issue. Re-constructing an accident can prove extremely complicated, especially when the event occurs without direct witnesses or when the scene is altered. In these cases, it is essential to adopt proper investigation pro-tocols in order to ensure the correct reconstruction of the dynamics. Case report: A man was found unconscious on the ground, having fallen from a height of approximately 2 meters, where there was a cabin in which a conveyor belt of raw materials for the production of cement ran. At the end of the path of this belt a scraper was found. An autopsy was carried out and the scraper present at the scene was examined and compared with the injuries on the victim. After the autopsy, the investigators returned to the scene and collected the traces found in the cabin. At the end of collecting the traces, the investigators simulated the dynamics of the event by turning on the conveyor belt and placing a scraper of the same dimensions and characteristics as the one found at the scene inside the cabin. Conclusion: The autopsy showed a maxillofacial trauma with multiple bruises on the face and a serious fracture of the epistropheus tooth. This trauma was therefore incompatible with a simple fall from 2 meters. The investigators created an experimental model that demonstrated a very high energy rebound of the tape when placed in contact with the scraper. This reconstruction made it possible to carry out a single report with the data collected by the medical examiner and the investigators, which was effective and exhaustive, allowing the Authority to be provided with the evidence to continue the investigations about the responsibilities of the worker and the employer.

Autoptic aspects in a case of autosomal dominant polycystic kidney disease.

Background: Polycystic kidney disease is a cystic genetic disease. There are two forms: an autosomal dominant one, more common and typical of adults, and an autosomal recessive one, rarer and present in childhood. The autosomal dominant form is caused by genetic mutations of the PKD1 gene in 85% of cases and of PKD2 in 10-15% of cases. Case Report: We reported a case of 56-year-old woman with ADPKD, who had a kidney transplant and who was hospitalized for respiratory failure from Covid 19 disease. She was intubated, sedated and dialyzed, treated with antibiotics, immunosuppressants, diuretics and heparin. CT scan of the abdomen showed multiple cysts of various sizes in the liver and multiple cysts in the kidneys. The patient died after 20 days because she was unresponsive to therapy. The autopsy showed milky ascitic fluid in the abdomen, massive gastric haemor-rhage, intestinal fungal plaques, hepatic and renal polycystosis. The kidneys measured a total of 27 cm with a total weight of about 9 kg. The liver parenchyma appeared cavernous with multiple cysts. The kidney cysts contained bloody liquid. Conclusions: The case demonstrates how important it is in these subjects to evaluate not only the kidneys but also the liver which could present polycystosis and cause liver failure, affecting the severity of the pathology and death. This data is important to emphasize in the clinical management of these patients a close monitoring of liver function also from a preventative perspective in life.

Analysis of toxicological findings related to immunofluorescence investigations.

Background: The subject of this article is the role of forensic toxicology in post-mortem examinations using immunofluorescence methods, its implications and its role in providing conclusive evidence for both criminal and civil proceedings. The aim of the study is to verify the correlation between the mode of death and the ingestion of exogenous substances and, if positive, to identify the category of substances ingested and assess their role in the cause of death. Materials and methods: A laboratory study was carried out, consisting of several phases: pre-analytical phase; analytical phase; post-analytical phase. The variables analyzed were sex, cause of death, age. Abused substances tested: amphetamines, methamphetamines, barbiturates, benzodiazepines, cocaine, methadone, opiates, tricyclic antidepressants, delta-9-tetrahydrocannabinol (cannabis), alcohol. Conclusions: Retrospective analysis was performed on a total sample of 55 cases. The most relevant data emerged: cocaine with an incidence of 7.3% (4 cases out of 55), amphetamines with 5.4% (3 cases in total). The results of the screening tests were then subjected to confirmatory tests. There is an association between the use of certain exogenous substances and an increased risk of certain causes of death, such as overdose, traffic accidents, cardiovascular deaths, etc. This paper has highlighted the possibility of using first level immunological tests, such as immunofluorescence, to provide preliminary answers to the judicial authority immediately after autopsy, and a quantitative deepening with further second level tests, such as gas chromatography, as a gold standard to determine the cause of death.

Forensic aspects analyzed in a case series of femicides.

Background: Gender-based violence against women and its lethal outcome, femicide, represent important issues around the world. Although governments have passed specific laws, official data on gender-related violence and femicide are often absent and/or incomplete, difficult to access, rarely updated, contested and underestimated due to stigma, victim blaming or issues of legal interpretation. Femicide is an intentional killing in which a woman is murdered by an individual for misogyny and gender-related reasons. The most common type is in fact intimate femicide, which occurs when the murdered woman and the aggressor have an intimate, family, cohabitation or similar relationship. Case series: We analyzed 15 cases of femicide for which crime scene investigation and autopsy were carried out. For each case, a psychological autopsy was carried out and the means used to determine the individual's death were analysed. The circumstances in which the murder occurred were also examined. Discussion: Overkilling was evidenced in all cases analyzed. Over-killing in forensic medicine is known as a specific type of homicide in which the number of injuries inflicted far exceeds the number of injuries required to kill the victim. Therefore, the medico-legal management of the cases examined is complicated due to the multiple lesions present on the corpse on the victims which make difficult: 1) the reconstruction of the dynamics of the crime 2) the number of blows inflicted 3) the analysis of the fatal blow 4) the imputability of the offender.

The artificial intelligence in autopsy and crime scene analysis.

Background: In the evolving field of forensic medicine, artificial intelligence (AI) technologies may revolutionize traditional autopsy practices by enhancing the precision and efficiency of postmortem examinations. Methods: A review of the literature was carried out on the Pub-med and Scopus search engines by inserting the keywords "artificial intelligence" AND "forensic" AND ("autopsy" OR "crime scene management" OR "forensic odontology" OR "post mortem interval" OR "forensic anthropology" OR "forensic sciences"). The works that analyzed the applications of artificial intelligence in the forensic and autopsy field were analyzed. Conclusion: The results showed the application of different forms of artificial intelligence such as machine learning, deep learning, robotics, artificial neural networks. Various applications are therefore possible in the autopsy field including forensic identification, analysis of radiological data through Virtopsy, estimation of the weapon used through analysis of firearm damage with ballistics, estimation of the Post-Mortem Interval (PMI), forensic toxicology. AI's potential to aid in the precise identification of causes of death, estimation of postmortem intervals. With forensic pathologists facing the constant challenge of making accurate diagnoses under pressure, AI applications can offer much-needed support by reducing subjective judgment and the inherent human error due to fatigue. Therefore, the integration of AI into autopsies, while promising in terms of efficiency and accuracy, demands a careful balance between technological advancement and ethical responsibility to ensure trust and integrity in forensic practices.

The role of operative protocols for the prevention of occupational infectious risk on the crime scene.

Background: Crime scenes are possible scenario of accidents for operators, despite those risks the are no operative protocols in literature. However, COVID-19 pandemic has affected in a positive manner the management of infectious risk, encouraging use of Personal protective equipment (PPE). The aim of the study is to deepen and examine the occupational risk of all health professionals involved in the analysis of the crime scene and biological material collection to develop an operational protocol that explains in detail all the strategies applicable to reduce it. Materials and Methods: We conducted a review of the literature researching among the main databases, such as: PUBMED, EMBASE, COCHRANE introducing as keywords: crime scene, medico-legal investigations, occupational risk, infections. Subsequently, we developed an operational protocol that is currently applied during the activity of the Institute of Forensic Medicine "Magna Graecia" of Catanzaro. Conclusion: The crime scene can show numerous dangers for operators, due to the presence of syringes, contaminated biological material or sharps or access to areas with poor hygienic and sanitary conditions. This paper shows various strategies that may be implemented to reduce the risk. The aim of this work is to focus on the occupational risk for operators by proposing an operative protocol showing in detail how to manage a crime scene by reducing the infectious risk for operators until the transfer of the body and the collected evidence to the morgue and to the laboratory.

New perspectives of forensic pathology through machine learning approach on autopsy data: a pilot study.

Background: The analysis, interpretation and storage of information is entrusted to the individual expert, who bases his judgments on the knowledge resulting from the experience. The aim of this experimental study is to analyse and introduce a new line of research applicable to forensic pathology, based on the use of artificial intelligence techniques as a possible tool for data collection and analysis. Methods: The sample analysed is represented by judicial autop-sies performed at the University of Catanzaro from 01/01/2020 to 31/12/2021. For each case were performed: study of medical records; autopsy; histological examinations; toxicological analysis of blood samples. Continuous variables were presented as means ± standard deviations, and categorical variables were expressed as percentages. A random forest regression model was conducted, as a machine learning approach, to estimate the importance of individual solid organ weight variables in predicting cause of death. Conclusions: This study aimed to evaluate autopsy data to aid in the description and study of forensic cases, using a machine learning approach. To date, this study appears to be the first to evaluate the weight of organs in predicting a cause of death. Artificial intelligence techniques are an optimal solution in solving forensic dilemmas. The results of this study demonstrate that routine data can be submitted using machine learning techniques in order to identify key elements of procedures that provide more information in relation to the predic-tion of cause of death.

Multiple suicidal gunshot wounds. Case reports and mini-review of literature.

Background: To determine the manner of death (MOD) and, there-fore, to classify the event as natural, suicidal, homicidal, or accidental is an essential and routine task in forensic medicine. The evaluation of MOD presents numerous difficulties due to unusual anamnestic and circumstantial data, in addition to autopsy findings and postmortem findings. Materials and Methods: A mini review of the literature on the topic was performed. Here we report two cases of uncommon self-inflicted multiple GWs (SMGWs) to the head and thorax, suspected of killing. The presence of more than one gunshot wound is suggestive of homi-cide, especially when they involve the head. A review of the literature on the topic was performed on PubMed's database, showing, although considered infrequent, cases documenting SMGWs are not rare. Conclusion: In the cases reported, the initial suspicion of involvement of third persons was excluded through the examination of the death scene, post-mortem (CT and autopsy) findings and clinical-circumstantial data. The analysis derived from the review of the related literature allowed us to highlight the presence of common findings which should be considered in the evaluation of such cases.

New methods in psychological autopsy in cases of doubtful suicides.

Background: Suicide is considered a global health emergency by the WHO. In suicide, the collection of testimonial data often encounters the refusal of family members to accept the hypothesis of a self-harming event and to provide clear information on the matter. The psychological autopsy is an investigative tool historically known for collecting information on the deceased, although to date there is no standard methodological protocol for conducting interviews with family members/next of kin. Materials and Methods: We present three dubious suicide cases: fuel-related death; hanging during a party; throat cutting with multiple stab wounds. During the interview the operators avoided pressing or direct questions about the event, preferring the interview with free discussion about the deceased (stream of consciousness). Conclusion: Initially, the relatives showed an attitude of clear rejection of the suicidal hypothesis with insistent requests for clarity on what had happened. Subsequently, through the use of free-form interviews, it was still possible to intercept, in the stories, predictive signs of suicidal ideation or psychiatric comorbidities previously un-treated and probably not accepted by the relatives, especially through the description of daily acts and household habits and environmental conditions of the deceased. The cases demonstrate the importance of using standardized methods with the use of free interviews with family members in order to indirectly investigate the event.

Supermarket shopping death: the role of forensic investigations in plastic bag suffocation.

Background: Plastic bag suffocation may represent a very complex enigma for the forensic pathologist. The aim of this work is to highlight how the resolution of plastic bag suffocation cases is possible through the use of various forensic investigations, including psychological one (psychological autopsy) and toxicological examinations, in order to be able to define the manner of death. Case report: A 70-year-old man was found by his daughter lying on the bed, with his head inside a plastic bag knotted around his neck. The daughter claimed to have immediately removed the bag, but the father was already dead. An autopsy was performed. The clinical history of the victim was analysed in search of reason that could lead to suicide. The statements of the people on the death scene were examined. Results were compared with the scientific literature: a literature review was performed on the search engine Pubmed, Scopus and Google Scholar using the keywords "plastic bag suffocation" and "death". The autopsy showed no typical signs of asphyxial death. Toxicological examinations revealed benzodiazepines in the urine. Investigations revealed that the victim had been suffering from severe depression. Conclusions: The literature review confirmed that the most used wrapper is the supermarket shopping bag. We emphasize that plastic bag suffocation is a very quick event that does not leave any evident sign: this rapidity does not allow to appreciate the typical elements of asphyxiated death (petechiae, cyanosis). It seems that the fatal mechanism is a cardio-inhibitory, rather than a hypoxic process.

The ghost dead: ethical and medico legal analysis on the Mediterranean tragedies.

Background: Cadaveric identification represents a legal, moral and medico-legal obligation and also fulfills the ethical function to allow the living to offer their dead a merciful burial. In the Mediterranean basin we have been witnessing for years a struggle for life where hundreds of migrants die in an attempt to reach Europe. For these people right to be recognized is not easy because of ante-death biological data are not always available for comparison, and DNA analysis is not always feasible cause for the absence of data with which to compare. In Italy a multidisciplinary protocol has been adopted that involves the acquisition of data provided by family members present in the countries of origin. Materials and Methods: Between August 2015 and December 2021, bodies of 879 migrants of various nationalities washed up on the shores of Sicily and Calabria. These men, women, and children, in various states of preservation, were examined. Each body underwent a multidisciplinary approach. External examination and autopsy aimed to determine the cause of death for judicial purposes and to facilitate individual identification. Whenever possible bodies underwent total body post-mortem computed tomography examination to identify fractures and prosthetic implants. including inspection of the third molar to provide an estimate of the age. Conclusions: The activity carried out in cooperation with Prefecture, Scientific Police, and National and International Red Cross highlighted the importance of employing multiple scientific skills to compensate for the lack of biological information. The importance of appropriate behaviors to avoid contamination and ensure proper preservation underlines the importance of the establishment of a dedicated database.

Sudden Unexpected Death in Epilepsy (SUDEP). Full forensic approach in two cases and review of literature.

Background: The SUDEP is defined as a sudden unexpected death in patients affected by epilepsy, with or without evidence of a seizure, excluding documented status epilepticus, in which postmortem examination does not reveal a toxicologic or anatomic cause of death. Materials and Method: Here we report two cases observed at the Institute of Forensic Medicine of Messina, regarding the phenomenon, that were analyzed by a multidisciplinary approach. Meantime a systematic review of literature was performed using PubMed and Scopus databases. Conclusion: Although the mechanisms of SUDEP are not fully understood, several studies have allowed the identification of different brain areas whose anomalous stimulation, during epileptic seizures, could interfere with the correct control of cardiovascular and respiratory activities. The study highlights the importance of a complete multidisciplinary forensic approach analyzing different aspects in people affected by epilepsy, with no other cause of death. Furthermore, reinforce the definition of SUDEP for uniform cause-of death certification in these cases.

Postmortem or Perimortem Injury? Presentation of an incredible court case in which flames are the protagonists of a murder.

Background: Establishing the cause of death when analysing burnt human remains is limiting due to thermal degradation. The heat generated by high combustion degrades the bone structure, definitively hiding the perimortem trauma in most cases, which is crucial for solving a court case. Case report: In November 2019, a completely burnt corpse was found inside a car set on fire near a location in Reggio Calabria, Italy. The corpse was subsequently subjected to an initial radiodiagnostic examination and an anthropological/medico-legal investigation, in order to confirm the biological profile of the unidentified subject, define the cause of death and assess the presence of perimortal lesions through macroscopic analysis of skull fragments subjected to fleshing. Conclusions: The soft tissue fleshing of the burnt skull fragments allowed the reconstruction of a partial calotte. Macroscopic analysis of the consolidated shell identified in the left fronto-parietal region a clear linear fracture, perimortal in nature, compatible with blunt trauma. Autopsy examination revealed the presence of carbonaceous residues within the larynx and especially the trachea, confirming ante-mortem combustion.The results of the autopsy examination and the anthropological analysis allowed us to state that the net linear fracture, perimortal in nature, caused the subject a complex encephalic trauma, resulting in loss of consciousness and subsequent death due to carbon monoxide inhalation. This result not only confirms the malicious hypothesis, but reveals a deliberate burning of the victim in order to conceal the evidence necessary to solve the forensic case.
