Suicide drowning in the non-coastal territory of Milan.

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 (61-80 years 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.
