Planned and unplanned complex suicides: Casuistry of the Institute of Legal Medicine of Parma (Italy)

Complex suicide is performed using more harmful methods, simultaneously or consecutively. In these cases, the distinction between suicide and homicide represents a challenge for forensic pathologists. In literature, complex suicide is divided in two subgroups: â planned complex suicideâ or â unplanned complex suicideâ depending from forensic features and often related to psychiatric variables. Aim of this study was to show the casuistry of complex suicide in Parma's Forensic service analyzing, for each case, the forensic medical problems (type and site of lesions on the body), and the supplementary data [Police's inspection report, toxicological analysis and psychiatric anamnesis (when available)], trying, through a multidisciplinary approach, to determine a possible correlation between the victim's mood and suicide's method chosen, whether planned or unplanned. Our results showed the importance of all the elements collected on the crime scene to distinguish suicide from homicide, and the correlation between bipolar disorder, borderline personality disorder and schizophrenia with unplanned complex suicide (because of the impulsiveness), and major depression disorder and anxiety disorder with planned complex suicide. Being able to understand the causes behind this extreme gesture may become important not only for forensic pathologists and judicial authority, but also, and above all, for the family as well.
