Arc-like curvilinear bullet pathways along inner surface of skull - two cases.

To provide example cases within the peer-reviewed literature of a phenomenon related to certain gunshot wounds of the head where the bullet pathway courses along the inner table of the skull. Presentation of two cases discovered at medicolegal autopsy. The two cases provide radiologic and autopsy demonstration of bullet pathways within the head where the projectiles track along the inner aspect of the cranium, in a circumferential manner, such that the bullets are recovered in a location on the opposite side of the brain/head, with no projectile pathway within the intervening deep structures of the brain. The cases provide photographic and radiologic autopsy documentation of the phenomenon, which is described in forensic pathology textbooks and rare peer-reviewed literature sources, but without photographic demonstration. Recognition of this phenomenon in the clinical setting, or when correlating autopsy external and radiologic findings with historical information, may provide an explanation for situations where immediate incapacitation does not occur following a gunshot wound of the head.

Fatal acute lemborexant Poisoning: An autopsy case report.

A 50-year-old male was found dead in a park. Postmortem analysis using liquid chromatography-tandem mass spectrometry revealed lemborexant concentrations of 1.651 µg/mL in blood from the right heart, 0.236 µg/mL in the urine, and 58.642 µg/mL in the stomach contents. Based on the autopsy findings and postmortem analyses, the cause of death was identified as acute lemborexant poisoning due to an overdose. Although lemborexant is generally considered safe, its excessive ingestion can be fatal. Since no lethal concentration of lemborexant has been reported, the blood levels in this case can serve as a reference. Despite its widespread clinical use, lemborexant is not detected by the rapid urine drug screening tests currently available in Japanese investigative agencies. Forensic pathologists must be vigilant in order not to overlook acute lemborexant poisoning.

Fatal Hemoperitoneum Secondary to a Spontaneous Splenic Vein Rupture.

Spontaneous hemoperitoneum is rare and is often labeled as idiopathic because the source of bleeding is never found. We report the case of a 35-year-old male who died of a splenic vein rupture. The decedent was a chronic alcoholic with a reported history of cirrhosis and medication noncompliance. Internal examination revealed pale visceral organs, marked hemoperitoneum, a fibrotic/nodular liver, esophageal varices, and a ruptured splenic vein. Pertinent microscopic findings include liver parenchyma with bridging fibrous septa, nodules of regenerating hepatocytes, and the presence of Mallory-Denk bodies. The immediate cause of death was determined to be splenic vein rupture with the underlying cause of death being chronic alcoholism. This case is reported to emphasize the importance of correlating past medical history with thorough vascular dissection in cases of spontaneous hemoperitoneum. In a patient with fatal hemoperitoneum and risk factors for splenic vein pathology (ie, cirrhosis, portal vein hypertension), a high suspicion should be kept for splenic vein rupture.

Sudden Death in Pediatric Patient With Dilated Cardiomyopathy Due to Founder Variant in NKX2-5: Case Report.

Background: The NKX2-5 gene encodes a transcription factor that plays a role in atrioventricular nodal and myocardial development. Pathogenic variants of NKX2-5 are associated with congenital heart disease and sudden cardiac death. The missense variant in this case is one of the more common ones in Northern Europe and has high penetrance in familial cases. To our knowledge, this is the youngest person who died due to this variant. Case summary: This was a healthy, asymptomatic 14-year-old male with well-managed mild congenital dilated cardiomyopathy who died unexpectedly in his home. Postmortem examination revealed the NKX2-5 pathogenic missense variant, p.Phe145Leu, as the only explicable cause of death. Discussion: We propose that immediate family members of those who die suddenly due to NKX2-5 disease undergo genetic counseling and longitudinal screening to include this gene, as pathogenic variants in the NKX2-5 gene may manifest in a time-dependent manner.

SARS-CoV-2 (COVID-19) Experience at an Academic Medical Examiner's Office.

Introduction: The coronavirus disease of 2019 (COVID-19) pandemic has resulted in a great deal of morbidity and mortality worldwide. Since most deaths related to COVID-19 are currently considered natural, and they tend to occur following a clinically recognized illness, many medical examiner/coroner offices within the United States do not take jurisdiction over the majority of COVID-19 deaths. Methods: In this review, we present the experience of a medium-sized medical examiner's office affiliated with an academic medical school institution, over the first 15 months of the COVID-19 pandemic. Results: Compared to a 15-month period that immediately preceded the pandemic, our office experienced a significant increase in the total number of reported deaths, scene investigations, full autopsies, natural deaths, accidents, homicides, and drug-related deaths, but a decrease in the number of suicides. Overall, our office performed 5 autopsies during the study period where COVID-19 was considered the primary cause of death, 4 cases where COVID-19 was considered a contributory cause of death, and 28 cases where COVID-19 testing was positive, but COVID-19 was not contributory to death. Discussion: The COVID-19 pandemic was accompanied by a sizeable increase in work volume within our academic medical examiner's office. Although this increased workload was not related to a large number of COVID-19-related deaths investigated by the office, there were numerous areas of increased workload that were likely secondarily related to the conditions associated with the pandemic.

Acute aconitine poisoning resulting from the ingestion of medicinal liquor.

Diester diterpenoid alkaloids (DDAs) are the main active ingredients of herbaceous perennial plants Aconitum. DDAs possess cardiotoxic and neurotoxic properties. Although most deaths caused by DDA poisoning are accidental, a few instances of suicide and homicide have been reported. Presented is a case of an acute aconitine (AC) poisoning following the ingestion of approximately 50 mL of homemade medicinal liquor. We described the clinical manifestations after poisoning and detailed postmortem changes, and detected the concentrations of AC and hypaconitine (HA) by liquid chromatography-tandem mass spectrometry (LC-MS/MS). The decedent experienced a burning sensation in the gastrointestinal tract after poisoning, followed by flushing and paralysis of the face and limbs, and severe cardiac arrhythmia. An autopsy revealed cyanosis of the lips and nail beds; conjunctival hemorrhage in both eyes; pulmonary edema; tissue hemorrhage and congestion in multiple organs; and inflammatory cell infiltration in the stomach, duodenum, pancreas, and cardiac muscle. The concentrations of AC and HA were as follows: cardiac blood, 38.4 ng/mL and 7.1 ng/mL; pericardial fluid, 7.3 ng/mL and 41 ng/mL; urine, 28.1 ng/mL and 574 ng/mL; bile, 38.5 ng/mL and 108 ng/mL; gastric contents, 0.06 mg and 0.56 mg; liver tissue, 10.7 ng/g and 109.6 ng/g; and medicinal liquor, 0.568 mg/mL and 0.664 mg/mL, respectively. The clinical manifestations, anatomy findings, and quantitative data on the concentrations of AC and HA in body fluids and tissues will aid forensic investigations of deaths caused by acute AC poisoning.

Poisoning with table salt while treating drug poisoning.

Hypernatremia is an increase in serum sodium concentration above 145 mmol/L. There are many causes of elevated sodium levels in the blood serum. One is incorrect actions performed by medical staff. The symptoms of excessively high serum sodium levels depend on the severity of hypernatremia, the rate of its increase and the accompanying volume disorders. Severe symptoms include altered consciousness, increased muscle tone and reflexes, convulsions, psychomotor hyperactivity or drowsiness (up to coma), respiratory failure, and even death. We present the case of a 45-year-old man who took seven tablets of a blood pressure-lowering drug, and paramedics subsequently administered a concentrated solution of table salt to induce vomiting. However, vomiting did not occur, leading to hypernatremia. Ultimately, the man survived but developed persistent cognitive dysfunction, including disordered short-term memory and encoding and retrieval of information from long-term memory, weakening of attention function and fatigue, and disorders in abstract thinking. The patient's family went to the prosecutor's office to investigate the possibility of medical malpractice. Experts found that the paramedics' actions were incorrect. Although it has been known for many years that table salt solutions should not be used to induce vomiting, unfortunately, both laypeople and medical professionals are still using this technique. Iatrogenic salt poisoning may end not only in serious health complications but also in legal consequences.

Analysis of unique atypical screwdriver injuries.

Fatalities caused by sharp and pointed instruments, especially screwdrivers, are not frequently observed in the United States. The shape of the screwdriver tip generally determines the resulting wounds that can range from linear, to rectangular or cross-shaped, often reflecting common screwdriver head shapes. Recognizing such patterns is crucial, as they can aid in identifying the potential weapon used in the crime. In the reported case, an adult male was found dead in his living room surrounded by a pool of blood, with multiple injuries. At autopsy, the pattern of penetration was consistent with that of a six-point star (Torx) screwdriver, which has never been reported as a deadly weapon in the literature before. A Torx screwdriver has a blunt head, resulting in hybrid injuries with both penetrating and blunt force features. Because of its rigid structure and narrow tip, a Torx screwdriver may forcefully penetrate the skin, soft tissues, and bone, causing severe injuries to the deep organs. The case highlights the importance for the forensic pathologist to examine and recognize atypical penetrating wounds for the identification and location of rare weapons. High-definition graphic documentation of the injuries allows thorough examination and comparison of injuries with potential weapons. When the weapon is not retrieved, detailed injury descriptions guide investigations toward searching for a screwdriver, improving the chances of identifying the weapon used to commit the crime.

Distinguishing injury patterns in fatal falls from heights versus pedestrian impacts: an autopsy study for differential diagnosis in ambiguous cases.

This study investigated the injury patterns associated with fatal falls from heights compared to individuals struck by cars, aiming to enhance the differential diagnosis in ambiguous cases, where it is unclear whether the body fell from nearby building or was left on the street following a road traffic incident. A retrospective review of comprehensive forensic reports from the Institute of Legal Medicine of the University of Rome "Tor Vergata" between 2012 and 2023 was conducted. The analysis included 232 cases, gathering data on internal organ injuries, skeletal fractures, external skin injuries, as well as pleural, peritoneal, and pericardial effusions. Bilateral lung injuries were significantly more common in falls from height (33.3%) compared to pedestrians (13.6%, p < 0.001). Liver injuries also occurred more frequently in fall victims (49.6%) than in pedestrians (28.2%, p < 0.001). Skull fractures were more frequent in falls from height (68.2%) versus individuals struck by cars (55.3%, p = 0.044), while unilateral leg fractures were more common in pedestrians (28.2%) compared to fall victims (16.3%, p = 0.029). External injuries, notably to the head and legs, were more frequent in pedestrians. The "Total Injured Skin Area" analysis revealed a significant discriminative power with an optimal cut-off of 84.2 cm², suggesting that injuries exceeding this threshold may be indicative of a pedestrian road fatality.

Death due to unrecognized intoxication of nifedipine in an adult.

PURPOSE: Diagnosis of drug intoxication in the medico-legal autopsy is challenging due to many factors such as non-specific clinical features and non-specific, inconclusive autopsy findings, etc. Thus, deaths due to drug intoxication can be misclassified in a low-resource setting where post-mortem toxicology testing is selective. The paper presents a fatal case of unrecognized nifedipine intoxication in an adult where the manner of death was undetermined after extensive investigation. METHOD: The liquid-liquid extraction using chloroform was carried out on a blood sample spiked with nifedipine. Subsequently, the post-mortem blood sample was analyzed and quantified using gas chromatography-mass spectrometry with electron ionization technique. RESULTS: The patient before death had symptoms, such as trismus, vomiting, and dizziness. The initial blood pressure and pulse rate were 94/56 mm Hg and 110 beats per minute, respectively. The respiratory rate was 20 breaths per minute. The post-mortem examination revealed no pathological changes or injuries in any organs. Upon histopathological examination, no significant findings that could have led to death were observed in any of the organs. The level of nifedipine in the peripheral blood, 0.645 µg/ml was determined to be either  close to or exceeding the reported fatal dose. The cause of death was ascertained as acute nifedipine intoxication. CONCLUSION: It is crucial to accurately determine the cause of death in cases that pose a significant threat to public health. This case highlights the challenges faced by forensic pathologists in scientifically ascertaining the cause of death accurately, especially in intoxication deaths, and the importance of comprehensive toxicology testing services including analytical toxicology for the integrity of the medico-legal death investigation system.

Postmortem Detection of "Clinically Undiagnosed" Diffuse Large B-Cell Lymphoma: Gross and Microscopic Findings.

Diffuse large B-cell lymphoma is considered the most found non-Hodgkin lymphoma in adults. Diffuse large B-cell lymphoma, which also occurs in sporadic forms, is associated with some pathological conditions, including human immunodeficiency virus infection, especially if it progresses to AIDS. The authors report the case of a 45-year-old man with AIDS in whom a postmortem diagnosis of diffuse large B-cell lymphoma was performed. The proposed images document extensive pluri-visceral involvement, already visible macroscopically, and subsequently confirmed through histological examination.

microRNAs as New Biomolecular Markers to Estimate Time since Death: A Systematic Review.

Estimating the post-mortem interval is still one of the most complex challenges in forensics. In fact, the main tools currently used are burdened by numerous limitations, which sometimes allow the time of death to be placed only within too large time intervals. In recent years, researchers have tried to identify new tools to try to narrow down the interval within which to place the time of death; among these, the analysis of microRNAs seems to be promising. An evidence-based systematic review of the literature has been conducted to evaluate the state of the art of knowledge, focusing on the potential correlation between miRNA degradation and PMI estimation. The research has been performed using the electronic databases PubMed, Scopus, and WOS. The results allowed us to highlight the usefulness of miRNAs both as markers for PMI estimation and for normalization, especially due to their stability. In fact, some miRNAs remain particularly stable for long periods and in different tissues, while others degrade faster. Furthermore, there are numerous factors capable of influencing the behavior of these molecules, among which the type of tissue, the cause of death, and the circadian rhythm appear to be the most relevant. Despite the promising results of the few articles present in the literature, because of the numerous limitations they are burdened by, further research is still necessary to achieve more solid and shareable results.

Assessing violent mechanical asphyxia in forensic pathology: State-of-the-art and unanswered questions.

Mechanical asphyxiation has been a common method used to commit homicide, including femicide, throughout history. A recent report by the United Nations has shed light on the issue of misidentification and concealment of gender-related killings, which makes it difficult to effectively fight against it. Forensic pathologists are frequently asked to examine cases involving suspected asphyxia to determine whether other persons have been involved. Therefore, medicolegal experts must look for signs of occlusion of the oral/nasal orifices, compression of the neck, or specific signs such as the "facie sympathique". There are situations where the physical signs are not distinctive enough to diagnose asphyxia, especially in cases where the individual has limited ability to resist external compression. In such cases, judicial autopsies should include an anatomical dissection of the neck structures through a layer-by-layer progression. It is important to search for the Amussat's sign, e.g., as part of a Forensic Clinical Anatomy approach. Additionally, individual anatomical variations, age or artefactual modifications, must be considered for the correct interpretation of findings. Microscopic examinations could aid in the diagnosis by providing additional findings, and several attempts have been made to identify unique markers of asphyxia through various laboratory techniques such as biochemistry, radiology and miRNA studies. However, no single finding or method has been identified as definitive. In the future, biomedical-legal sciences will have to rely on scientific research and the retrospective case series to provide a scientific framework on which to base their hypothesis, giving weight to evidence in the trial.

Forensic significance of postmortem pink teeth: A narrative review.

OBJECTIVE: To review the phenomenon of postmortem pink teeth, exploring its etiology, correlation with the cause of death, and the potential forensic significance of this medico-legal finding. METHODS: A comprehensive literature search was conducted using databases such as PubMed, Scopus, and B-on, employing keywords like "Forensic Pathology," "Forensic Dentistry," "Pink Teeth," and "Medico-legal aspects." The search included studies without temporal limits to gather extensive data on the postmortem pink teeth phenomenon. RESULTS: The postmortem pink teeth phenomenon is characterized by a red-pink discoloration of the dentin, typically sparing the enamel. It is most often observed in moist environments and cases involving water immersion, strangulation, and carbon monoxide poisoning. The study found no consistent relationship between the pink discoloration and specific causes of death, suggesting the phenomenon is more closely related to environmental conditions and the state of decomposition. The pink coloration is more prevalent in anterior, single-rooted teeth and younger individuals. CONCLUSION: The postmortem pink teeth phenomenon remains a complex and enigmatic finding in forensic science. While it does not conclusively indicate a specific cause of death, understanding its occurrence can aid forensic investigations. Further research is needed to elucidate this phenomenon's mechanisms and validate its forensic relevance.

Hereditary thrombophilia as a possible risk factor for severe disease in COVID-19: a case series.

PURPOSE: The risk factors that modulate one's susceptibility for severe COVID-19 have been well documented. Despite this, hypercoagulability remains an often overlooked risk factor for severe disease for COVID-19. Because COVID-19 infection is a risk factor for hypercoagulability, a reasonable presumption/hypothesis is that patients with hereditary thrombophilia would be at a higher risk of thrombotic complications associated with COVID-19 infection. METHODS: This case report details two cases where previously unknown hereditary thrombophilias likely contributed to the mortality of COVID-19 patients. RESULTS: The first COVID-19 patient's cause of death was pulmonary thromboemboli from deep vein thrombosis due to heterozygous MTHFR C667T and heterozygous PAI-1 4G/5G mutations. The second COVID-19 patient's cause of death was an acute myocardial infarct due to a coronary artery thrombosis in the setting of heterozygous MTHFR A1298C and homozygous PAI-1 4G/5G mutations. In each case, COVID-19 infection was also considered contributory to death. CONCLUSION: The occurrence of these fatal thrombotic events in COVID-19 patients with hereditary thrombophilias raises questions as to whether this combination of thrombotic risk factors for hypercoagulability may have placed patients at a significant enough risk to experience these fatal thrombotic complications. Thus, while not sufficient alone to prove that SARS-CoV-2 patients with hereditary thrombophilias are at increased risk for thrombotic complications, these two cases indicate that further investigation is warranted into elucidating the relationship between thrombotic risk factors as it may identify an additional high-risk medical condition for COVID-19 and have important diagnostic and therapeutic ramifications.

Potential Role of mRNA in Estimating Postmortem Interval: A Systematic Review.

Although the postmortem interval estimation still represents one of the main goals of forensic medicine, there are still several limitations that weigh on the methods most used for its determination: for this reason, even today, precisely estimating the postmortem interval remains one of the most important challenges in the forensic pathology field. To try to overcome these limitations, in recent years, numerous studies have been conducted on the potential use of the mRNA degradation time for reaching a more precise post mortem interval (PMI) estimation. An evidence-based systematic review of the literature has been conducted to evaluate the state of the art of the knowledge focusing on the potential correlation between mRNA degradation and PMI estimation. The research has been performed using the electronic databases PubMed and Scopus. The analysis conducted made it possible to confirm the potential applicability of mRNA for reaching a more precise PMI estimation. The analysis of the results highlighted the usefulness of some mRNAs, such as ß-actin and glyceraldehyde-3-phosphate dehydrogenase (GAPDH) mRNA, especially in short time frames, within a few hours or days of death. The matrices on which these analyses were conducted were also analyzed, resulting in less exposure to the external environment, including the heart, brain, and dental pulp. The major limitations were also reported, including the short time intervals analyzed in most of the articles, the lack of mathematical models, and the failure to report the error rate between the mRNA degradation time and PMI. Given the still small number of published articles, the lack of globally recognized standardized methods, and the numerous techniques used to evaluate the mRNA degradation times, numerous and larger studies are still necessary to reach more solid and shared evidence.

Novel Immunohistochemical and Morphological Approaches in a Retrospective Study of Post-Mortem Myocarditis.

Background and Objectives: This study presents a retrospective analysis of 26 autopsy cases from a single centre, primarily focusing on forensic cases, with a majority of male individuals. Materials and Methods: We systematically analysed autopsy reports and cardiac tissue slides using haematoxylin-eosin stain and immunohistochemistry for CD3, CD163, and IL-6. The histological assessment evaluated key variables such as inflammation severity, necrosis, and background changes using a standardised grading system. Quantitative analysis of immunohistochemical markers was performed, calculating the percentage of positively stained cells within the inflammatory infiltrate. Results: The average age was 51.6 years, slightly skewed towards older males. The fatalities varied widely, with sudden death and drug abuse being the most common conditions linked to myocarditis findings on histological examination. A strong correlation was found between the severity of inflammation (measured by size within a myocardium section) and the scoring system based on the number of inflammatory foci per section (p ≤ 0.001). Most cases showed mild to minimal fibrosis, with some exhibiting moderate to severe fibrosis, arteriosclerosis, and myocyte hypertrophy. The presence of protein CD3 in the inflammatory infiltrate revealed a moderate inverse correlation between the CD3 values and the severity of inflammation and necrosis, and a strong inverse correlation with neutrophil levels. CD3 levels were higher in sudden death cases and lower in cases with numerous inflammatory foci, highlighting the discreet nature of lymphocytic myocarditis. Macrophage presence, assessed using CD163, showed a moderate inverse correlation with neutrophil levels and significant differences between sudden death and non-sudden death cases. Macrophage-rich inflammation was observed in cases with pneumonia/bronchopneumonia-associated lesions. IL-6 expression showed a moderate direct correlation with inflammation severity (p = 0.028), severity of necrosis (p = 0.005), and the number of inflammatory foci per section (p = 0.047). A moderate inverse correlation was found between CD3 and IL-6 expression (p = 0.005). Conclusions: These findings highlight the need for a unique immunohistochemical approach in forensic cases of myocarditis, differing from guidelines for endomyocardial biopsies due to diverse inflammatory cells. The study suggests exploring inflammatory chemokines within myocarditis foci for their significance in clinical scenarios. Specifically, IL-6, a crucial pro-inflammatory interleukin, correlated significantly with the severity of inflammation and necrosis (p < 0.05). This study provides novel and valuable insights into the histopathological and immunological markers of myocarditis in autopsy cases.

Avalanche fatalities in Czech Republic: a 23-years retrospective study.

Avalanche fatalities are quite rare in the Czech Republic. Due to the presence of avalanche fields in the two Czech mountains, forensic pathologists at some forensic medicine departments may encounter this specific mechanism of accidental death. The authors summarize medicolegal aspects of deaths in avalanches in the territory of the Czech Republic for the twenty-three-year period between 1993-2015. Ten avalanche fatalities were recorded during study period. The studied group consisted of nine male and one female victims. The average age of the deceased was 27.9 years. Skiers or ski-alpinists died in the avalanche in five cases (50%), climbers in two cases (20%), snowboarders in one case (10%), cross-country skiers in one case (10%) and in one case it was a fatality of child playing on a snowy hill (10%). The cause of death was suffocation in four cases (40%), blunt trauma in four cases (40%), and in the remaining two cases it was the survival of trapped persons several hours after being rescued from the avalanche in the hospital; both victims subsequently died as a result of prolonged shock (20%) due to a combination of prolonged suffocation and hypothermia. The time interval from the fall of the avalanche to the rescue of the trapped person was in the range of minutes to 3 hours. The presence of alcohol or drugs was not detected in any studied case.

Ritual male circumcision: a case of fatal hemorrhagic shock in a 28-day-old infant.

Background: Male circumcision (MC) is a practice involving the surgical excision of the foreskin to expose the glans and it is often performed for religious reasons. Ritual circumcision is frequently carried out by unqualified practitioners in inadequate settings, which can also lead to the death of the individual. Case Report: A 28-day-old infant was undergoing circumcision by a man that performed the circumcision using a razor blade. During the same day, the child experienced continuous bleeding from the wound and, finally, died after about 20 hours. At autopsy, a cutaneous sharp injury was revealed with ablation of the foreskin and part of the penile body. The lesion had irregular and jagged margins, with diffuse hemorrhagic infiltration. The glans and upper fascia of the penis appeared edematous and hyperemic and there were abundant hemorrhagic infiltrations in the frenulum area. The child's death was attributed to hemorrhagic shock in a child undergoing genital mutilation surgery. The finding of a significant hemorrhagic infiltration of the frenulum region indicated that the frenular artery had been severed. Conclusions: Around 35% of ritual male circumcisions are performed clandestinely in Italy, and typically by unqualified practitioners. In such events, the forensic investigation of the injuries inflicted on the victim allows for determining whether the procedure was performed appropriately or not, to verify the existence of a causal link between the procedure itself and the death of the individual.

Complex suicide by drowning and stabbing: first italian case reported in literature.

Background: "Complex suicide" refers to suicides in which more than one suicide method is applied. The victim can either plan different and simultaneous ways of death, to prevent any failures, or change the method because the first one fails or turns out to be too painful. Case report: A Middle-age-man was found dead inside a car, in a field, near the seaside. Clothes were intact, wet, and smeared with mud and gravel. His shirt had dried whitish biological material on the thoracic area, referable to oedema fluid, his trousers were down to his ankles exposing external genitalia. Inside the car, a kitchen-serrated blade knife and scissors were found, both smeared with dried blood material. Cadaveric inspection showed: multiple superficial stab/cut injuries; nasal cavities leaking aqueous-like fluid; triangular and linear stab lesions all over the body; hesitation marks on both latero-cervical regions and both wrists; no defensive injuries referrable to third parties; maceration over both palmar and plantar surfaces. Autopsy showed: hemorrhagic infiltration for thoracic muscles; expanded and heavily congested lungs. Conclusions: This is the first Italian case, and one of the few cases reported in major literature (third case worldwide), of unplanned complex suicide achieved through stabbing and drowning by a man with no psychiatric or substances abuse history. Therefore, analyzing any evidence to distinguish this kind of sudden/unnatural death from accidental or homicidal ones is mandatory. Such cases require a flawless approach to judicial inspection, autopsy, and toxicological exams. Moreover, a multidisciplinary perspective including psychiatric criminological investigation is needed.
