ANALISI STATISTICO-CRIMINOLOGICA DEGLI OMICIDI OCCORSI NEL DISTRETTO GIUDIZIARIO DI MILANO E MONZA NEGLI ANNI 2006-2021

A retrospective analysis was conducted of the homicides that occurred in the area under the jurisdiction of the Public Prosecutors of Milan and Monza and were autopsied at the Institute of Forensic Medicine of Milan between 1 January 2006 and 31 December 2021. The data was collected from autopsy reports, interviews with the victims' families, clinical records and local newspapers. In total, of the 11,480 autopsies performed in the period of interest, 301 were found to be attributable to voluntary homicides. 94 (31.23%) crimes occurred within the family context, and 207 (68.77%) outside. The following were evaluated: the personal characteristics of the subjects involved (sex, age, geographical origin); the risk factors present in victims and killers; the characteristics of the event (place, modality). The results were then analyzed by differentiating and comparing the two groups (intra- and extra-family). Statistically significant differences emerged for many of the variables analysed. The people involved in family murders are on average older, almost always Italian and the involvement of women is greater than in the other group (although predominantly men are always involved). Great differences also concerned risk factors: much more often those who kill outside the family context have already committed previous crimes or are involved in illicit trafficking; within the family, however, psychic pathologies such as depression prevail among the perpetrators and illness/non-self-sufficiency among the victims. Finally, in addition to the reliable differences inherent in the place of the crime (those who kill a family member do it inside the shared house, in almost all cases), there was also a greater use of weapons (firearms or bladed weapons) in those who kill outside the family. It can thus be assumed that homicides inside and outside the family have few points in common, and that the typology of subjects involved is substantially different.
