Psychopathy-associated personality traits influence crime-scene behavior in male homicide offenders.

We investigated whether psychopathy-associated personality traits and behavioral styles affect the manner in which homicides are committed or the motives underlying them. Using three nationwide registries and an in-house homicide database based on court verdicts, we identified all cases of homicide in Sweden during the years 2007, 2008 and 2009. In 72 male offenders who had undergone assessment using the Psychopathy Checklist - Revised (PCL-R), the manner of homicide was categorized as instrumental or expressive, and the motive as belonging to one of five categories: (1) intimate-partner or family-related homicide; (2) homicide occurring during altercations, (3) robberies or burglaries, or (4) criminal conflicts; or (5) sexual homicide.

Emergence of Huntington Disease in a Man With a Premorbid Criminal Lifestyle.

We present here a case in which Huntington disease (HD) was diagnosed upon forensic-psychiatric evaluation of a 34-year-old male repeat offender. Despite a family history of HD, as well as overt delusions and motor pathology, the disease had not been recognized at an earlier stage, and the patient was serving a prison sentence at the time of diagnosis. The case highlights difficulties court officials may face with regard to identifying severe psychiatric and neurological disorders in repeat offenders.

Injury-Related Healthcare Use and Risk of Filicide Victimization: A Population-Based Case-Control Study.

Research on child-related risk factors for filicide is scant. We investigated whether prior healthcare use for injury (including poisoning) influences filicide risk. Victims (0-14 years; n = 71) were identified in a national autopsy database for the years 1994-2012 and compared to matched, general population controls (n = 355).

Pre-offense alcohol intake in homicide offenders and victims: A forensic-toxicological case-control study.

Background And Aim: Alcohol is associated with violent behavior, although little is known regarding to what extent alcohol increases homicide risk. We aimed to estimate risks of homicide offending and victimization conferred by the presence of ethanol in blood by using toxicological data from homicide victims and offenders and from controls who had died in vehicle-related accidents.

Methods: From nationwide governmental registries and databases, forensic-toxicological results were retrieved for victims (n = 200) and offenders (n = 105) of homicides committed during the years 2007-2009 and individuals killed in vehicle-related accidents (n = 1629) during the years 2006-2014.

Psychotropic Medications in Swedish Homicide Victims and Offenders: A Forensic-Toxicological Case-Control Study of Adherence and Recreational Use.

Objective: We aimed to assess the extent to which adherence to, and recreational use of, psychotropic medications influence the risk of homicide offending and victimization.

Methods: We conducted a population-based case-control study by way of linking a nationwide registry of dispensed prescriptions with a forensic-toxicological database. Homicide victims (n = 200) and offenders (n = 105) were identified for the years 2007-2009 and vehicle-accident controls (n = 1,643) for the years 2006-2013.

A population-based study on toxicological findings in Swedish homicide victims and offenders from 2007 to 2009.

Background And Objectives: Previous research on the toxicology of homicide has shown that about half of offenders and victims have psychoactive substances in their blood. The purpose of this study was to examine this topic in a Swedish setting.

Methods: Toxicological data were sought in a database for all victims (n=273) and perpetrators (n=257) of homicide in Sweden from 2007 to 2009.
