Literature on electrocution in Italy is limited. The authors have focused their attention on the use of scanning electron microscope/energy-dispersive X-ray analysis in order to evaluate the current mark even on paraffin-embedded samples. A total of 24,104 autopsies were performed at the Section of Legal Medicine of Milan (1993–2017); all cases of death caused by electrocution (low and high voltage) were selected. We assessed a regular histological examination, a toxicological examination and detected metallisation with energy-dispersive X-ray spectroscopy analysis on paraffin-embedded tissues of typical current marks. We collected 27 high-voltage fatalities and five cases of low-voltage suicide electrocution; the technique revealed itself as sensitive. In all cases, microscopic examination highlighted the typical signs of electric current and thermal damage but the histochemical specific stainings for copper and iron gave negative results. Scanning electron microscope/energy-dispersive X-ray analysis, assessed on these same samples, even when paraffin-embedded, however, enabled us to detect these elements and differentiate between the various metal residues involved in the electrocution process. Based on their experience, authors advise the use of scanning electron microscope/energy-dispersive X-ray analysis on electrocution deaths to provide information for forensic diagnosis.

Plastic Bag Suffocation is a rare cause of death in developed countries and almost unknown in the rest of the world. This study aims to retrospectively evaluate cases of PBS _asphyxia in Milan's Department of Legal Medicine from 1993 to 2013. Cases were selected from the database of 21,472 autopsies performed in the considered timeframe. One hundred and one cases were considered to be cases of Plastic Bag Suffocation, comprised of 100 suicides, no accidental events and 1 homicide. The most relevant elements pertaining to this type of death were evaluated for both the corpses and the crime scenes. From this study the typical PBS victim is an adult male, aged 52.3 years on average, depressed or afflicted by chronic or terminal diseases, and found at home. In 42.6% of cases, the victims were found with the plastic bag still positioned over their head, fastened by tying. Also common among these cases are drugs, alcohol and chemical abuses. According to the collected data, it is impossible to outline a pathognomonic detrimental background that leads to this cause of death. Crime scene investigation is, therefore, the one and only technical resource for evaluating these cases.

Introduction: A cadaver in water sets a relevant issue for the forensic pathologist, concerning the differential diagnosis between homicide, suicide, accidental event, and natural death in water. In the present study, the drowning suicides in a non-coastal territory are analyzed, discussing the main diagnostic difficulties, the preventive intervention, and the strategies for outlining the profile of a “mean victim” that is at risk of committing suicide by drowning. Methods: The cases of drowning suicide were extrapolated by the database of the 21,472 autopsies performed at the Civic Morgue of Milan, in the period between 1993 and 2013. Results: Drowning represents the fifth cause of suicide registered in Milan for the study period, with 139 cases (3.8% of all suicides). Victims were mainly elderly males (61–80years old) with a history of psychiatric diseases in pharmacological therapy; they committed suicide mainly during summer, in the rivers. The diatoms test was positive in 82 cases (59%) and highlighted typical taxa of fresh water. Alcohol and illicit drugs were not noticed, at high levels. Conclusion: Drowning suicide occurs even in a non-coastal territory, far from the sea, if there is an easy access to the water: specifically, many natural and artificial waterways in the Milan district represent a high-risk factor predisposing the drowning suicide.
