Homicide-Suicide and multidisciplinary approach: case series and a review of the literature.

Introduction: Despite being relatively rare in our country, murder-suicide phenomena have garnered increasing media attention over the years. However, actual data on their prevalence and characteristics remain limited. This study aims to describe and characterize all murder/suicide events reported at the Institute of Forensic Medicine in the Province of Messina, with a particular focus on distinguishing between cases of filicide/suicide and dyadic deaths. Materials and Methods: A retrospective observational analysis of judicial cases from 2018 to 2023 was conducted. Injuries were primarily localized to the head, neck, and chest for women, and to the head for men. In the case of filicides, death occurred through an asphyxiation mechanism, followed by the mother's suicide by hanging or falling. Conclusion: Within the scope of the medical examiner's activities, it is clear that acquiring more information through a standardized technical investigation and adopting a uniform approach could enhance the quality of the forensic service provided daily. This improvement, which would be in the interest of institutions and civil society, could be achieved through the sharing of procedures at both national and international levels.

Homicidal or suicidal death? Evidence-based approach to assessing cause of death in a peculiar forensic case.

Background: In recent years, the improvement of common standards of forensic practice has received attention to promote an unambiguous and better-quality forensic investigation method. Although most hanging deaths are attributed to suicides, cases occasionally occur due to accidents or homicides. From an investigative point of view, hanging deaths are usually straightforward, but unusual circumstances may raise suspicions of crime. This includes complex suicides, which are rare events pursued by victims with two or more different fatal methods and can be classified as planned or unplanned, depends on whether the methods are applied simultaneously or sequentially. The multiplicity of injuries detected can often lead to misinterpretations, thus making a multidisciplinary approach extremely important. Case Report: A 44-year-old man, after requesting law enforcement, has been instead found inside a garden of an uninhabited property located a few kilometers away from his own property, suspended from a beam with wire; the wire created a noose at the back of his head, his hands were placed at his neck, and stab wounds were found. Conclusions: The crime scene investigation, interview of relatives, autopsy, histological and toxicological examinations, and GAP led to the determination that the death was suicide. This comprehensive approach emphasizes the importance of meticulous investigation and analysis to reach accurate conclusions in forensic cases.

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.
