Background and Aims:

The homicide phenomenon is a complex phenomenon that enhances Man complexity. This study aims to contribute to a better understanding of this phenomenon and its protagonists.

Methods:

Data were collected from clinical records of a Forensic Psychiatry Unit (Magalhaes Lemos Hospital) using a specific clinical protocol, being selected those with “homicide or homicide attempt” as the motive for evaluation.

Results and Discussion:

The sample was mainly formed by men (94.4%M vs. 5.6%F), with an average age of 37.78 years-old (sd +- 13.63), mostly single (n=25; 53.2%) and unemployed (n=24; 44.4%). The majority of the individuals were detained in a prisional facility (n=35; 64.8%). Thirteen of the victims were first degree relatives to the murderers. Homicide was consumed in 29 cases and in 25 of them it was a failed attempt. Twelve individuals (22.2%) were under suspicion of drug abuse (mainly alcohol) at the moment of the crime. The murderers percentage with psychiatric surveillance was 40.7% (n=22); 90.7% (n=49) had a psychiatric diagnosis and 27.8% (n=15) had a Psychotic Disorder. There were found a significant number of individuals with mental retardation and personality disorder. The conclusion of psychiatric forensic evaluation was “criminal responsibility” in thirty individuals (55.6%). Twenty individuals were considered “not criminally responsible” and psychiatric treatment and security measures were proposed.

Conclusions:

The homicide act of the individuals proposed for Forensic Psychiatric evaluation seems to be an isolated phenomenon that appears mostly in individuals with mental illness, often those having alcohol abuse or dependence.
