Mental disorders of male parricidal offenders: a study of offenders in forensic psychiatric examination in Finland during 1973-2004

Parricide, Mental Illness, and Parental Proximity: The Gendered Contexts of Parricide in England and Wales

Parricide is underresearched in the UK, and the contexts of this gendered form of violence are poorly understood. Heide's typology provides an advanced understanding of parricide in the United States, where the majority of parent-killings involve firearms. This article develops a UK-based analysis of the contexts of parricide, combining national statistics with police case study data (n = 57) and case review data (n = 21). Our findings indicate that mental illness plays a key role, combined with a gendered context of "parental proximity" and the simultaneous responsibilization and marginalization of parent-victims (particularly mothers), supporting the need for feminist analyses of parricide.

From overkill to beheading: A case report of a schizophrenic matricide

Initial evidence exists on a subtype of matricide committed by subjects suffering from severe mental disorders. Matricide perpetrators often undergo a forensic psychiatric evaluation during the subsequent criminal trial because of supposed legal insanity. The few studies on matricide by mentally disordered perpetrators suggested a possible association between such extreme form of violence and schizophrenia spectrum disorders, especially in case of active delusions or hallucinations.

METHODS

we analyze a case of a young male with a recent diagnosis of psychotic disorder who committed matricide by inflicting multiple injuries and beheading. Data emerging from the forensic pathological analysis of the victim, as well as the forensic psychiatric analysis of the matricide perpetrator are discussed within an interdisciplinary perspective.

RESULTS

the autopsy revealed multiple stab wounds in the regions of the upper limbs, abdomen, chest, and neck, the latter determining beheading. The forensic psychiatric evaluation yielded a diagnosis of schizophrenia and clarified the causal role in the homicidal behavioral of active psychotic symptoms.

CONCLUSION

the specific type of delusional content, and perpetrator-victim relationship might contribute explaining a subtype of extremely violent homicide in recent onset schizophrenia.

Attempted and Completed Parricides in South Africa, 1990-2019

Previous studies of parricide have been carried out predominantly in a Western context, in North America, Australia, and Western Europe. To date, only a handful of studies in parricide have been conducted in continental Africa. Previous studies in Ghana and Zimbabwe note that there may be culture-specific ways in which parricides may be shaped by the norms and cultural beliefs systems within those respective countries. Missing from the literature is an examination of parricides in South Africa. Using newspapers and court records, this article examines the offense and offender characteristics of parricides in South Africa. Our findings suggest that residential patterns of families may shape the offense characteristics found in South African parricides.

Matricide, parricide, and filicide: Are major mental disorders or personality disorders involved? Assessment of criminal responsibility in Brazilian cases

Violence committed by individuals with severe mental disorders has become a growing focus of interest among physicians, law enforcement officials, and the general population. Homicide involving relatives, specially parricide, matricide, and filicide, despite the relatively low incidence of these crimes, may be enigmatic, so forensic psychiatrist are frequently called on the courts to answer questions about insanity and criminal responsibility. The current study aims to describe Brazilian cases of parricide, matricide, and filicide associated with presence of major mental disorders and personality disorders, discussing the assessment of criminal responsibility in each case. The case series described were specifically related to people with mental illness, as bipolar disorder, schizophrenia, and borderline personality with comorbidity of drug abuse. Two of them were considered not guilty by reason of insanity, and the other one was considered partially criminally responsible, according to Brazilian Law and Forensic Psychiatric Reports of the cases. The justice determined compulsory psychiatric treatment for all of them. The question of criminal responsibility of individuals with mental disorders is challenging for criminal justice, psychiatry, and society. Adequate treatment is mandatory to prevent crimes involving mental disorders, as shown in literature. The verification of criminal responsibility is essential for persons' adequate referral in any system of criminal law, thus protecting human rights and referring those who need psychiatric treatment.

Who Are the Victims of NGRI Acquittees? A Study of Belgian Internees

BACKGROUND

The limited literature on victim characteristics of offenders found not guilty by reason of insanity (NGRI) shows that most victims are adults who are known to the offender. It is currently unclear whether victims are mainly male or female or whether there are differences in the type of victims according to the offenders' psychiatric disorder.

METHOD

Victim characteristics were retrospectively collected from 362 NGRI acquittees, and the influence of psychiatric diagnoses on victim profiles was examined.

RESULTS

Victims were mainly adult acquaintances and were equally likely to be male or female. Family members and caregivers were the most frequent type of acquaintance victims. Further analyses suggest that these victim characteristics are similar for perpetrators with different psychiatric diagnoses.

CONCLUSION

Victimization of strangers and minors was unlikely in NGRI offenders.

Comparative study of aggression - Dangerousness on patients with paranoid schizophrenia: Focus on demographic data, PANSS, drug use and aggressiveness

This cross sectional study aimed to compare the differences in psychopathology of Greek homicide and homicide attempters, patients with schizophrenia, with non violent individuals, suffering from schizophrenia. The study compared three Groups of 220 men, diagnosed with schizophrenia: (a) Group Α (Schizophrenia - No violence, (b) Group Β (Schizophrenia - with violence or violent crime), (c) Group C (Schizophrenia - not guilty by reason of insanity - violent crime). Several psychometric tools were used, such as M.I.N·I (Mini-International Neuropsychiatric Interview), PANSS scale (Positive and Negative Symptoms Scale). Most subjects suffered from paranoid schizophrenia. On factors such as demographic characteristics (i.e. current occupational status, living status), statistically significant findings were shown for Groups B and C vs Group A. Predisposing psychosocial factors, such as family conflicts and aggressiveness against family, were found to be statistically significant in differentiating violent versus nonviolent individuals with psychosis. They differed significantly in factors like history of juvenile delinquency, but also in the type of aggressiveness in general. These differences were confirmed on PANSS scale. In conclusion, the longer the history of aggressiveness is presented, the greater the chances are of individuals falling into Group C and it is possible to spend several years from the onset of the disease until the moment of crime.

Exploring Fatal and Non-Fatal Violence Against Parents: Challenging the Orthodoxy of Abused Adolescent Perpetrators

An examination of scholarly literature concerning fatal violence (i.e., parricide) and non-fatal violence toward parents reveals dominant themes of mental illness, child abuse, and pathology based on a research paradigm that focuses on adolescent perpetrators and, to a lesser extent, elderly victims. This article presents a critical analysis of this literature and argues for a more contextualized approach to the study of violence against parents. It is argued that criminologists should widen their methodological lens to examine this issue from a life course perspective and draw on conceptual tools such as developmental pathways, sources of conflict, and intersectionality to allow for an analysis that can offer new ways of thinking about violence toward parents.

Matricide by Mentally Disordered Sons: Gaining a Criminological Understanding Beyond Mental Illness--A Descriptive Study

Matricide is one of the rarest of reported murders and has always been considered one of the most abhorrent crimes. Psychiatric investigations as to why a son might murder his mother yield indications of a high rate of mental illness, primarily psychotic disorders, in perpetrators. In an attempt to gain an in-depth understanding of the role of the mother-son bond in the etiology of matricide by mentally disordered sons, this article presents a qualitative study of nine cases of matricide examined at two Italian Forensic Psychiatry Departments between 2005 and 2010 and retrospective analysis of forensic psychiatry reports on the offenders. Most matricides suffered from psychotic disorders, especially schizophrenia. Nevertheless, not all the perpetrators had psychotic symptoms at the time of the crime. A "pathologic" mother-son bond was found in all cases. However, mental illness is not the only variable related to matricide and, taken alone, is not enough to explain the crime. Several factors in the history of the mother and son need to be probed, especially how their relationship developed over the years. The peculiar dynamics of the mother-son relationship and the unique personalities and life experiences of both subjects are the real key to cases of matricide.

A descriptive and follow-up study of 40 parricidal patients hospitalized in a French secure unit over a 15-year period

Parricide is rare and represents 3% of all homicides in France, and 4% of resolved homicides in North America. Consequently, related international literature is sparse, especially concerning the evolution of offenders, and most studies concern small samples or anecdotal cases. We wished to identify the main characteristics of parricidal subjects and their victims, and to assess the socioclinical evolution of the offenders after the assault. To this end, we first studied the sociodemographic, clinical and forensic characteristics of all parricidal patients admitted to France's Henri Colin secure unit between 1996 and 2010 (40 patients). We also assessed the evolution of the 36 patients who had left the secure unit, using questionnaires sent to the psychiatric hospitals where the patients were transferred. We found most offenders to be men (97.5%), with a mean age of 28 years, who were mostly single, unemployed, living with the victim prior to the assault (77.5%), and with a history of psychiatric disorder (72.5%). The population of offenders also displayed an overrepresentation of schizophrenia (87.5%), significant toxic exposure and criminal or violent history. Some patients had attempted suicide before or right after the offense. The assault was mostly committed in the parent's house with an edged weapon, and was characterized by brutality and lack of premeditation. Precipitating factors included substance use and cessation of psychotropic medication. Matricide was more frequent than patricide. At the time of this study, half of the parricidal patients were working or attending therapeutic activities, and most were actively keeping in contact with their family, living as compliant outpatients with no signs of violent behavior. The results of our study on 40 parricidal patients are consistent with data in the literature. With regard to sample evolution, family and community reintegration was relatively effective considering the seriousness of the offense. Several biases in our study disallow the generalization of these findings, and further studies are needed.

Matricide and stepmatricide victims and offenders: an empirical analysis of U.S. arrest data

Almost all of the clinical and empirical literature on female parricide victims focuses on mothers killed, with only little information available on stepmothers murdered. This study is the first to compare the victim, offender, and case correlates in incidents when mothers and stepmothers were killed. Supplementary Homicide Report Data for 1976-2007 were used to investigate similarities and differences between the two female victim types in the United States. Similarities between stepmothers and mothers included that more than 70% were White and killed in single victim, single offender incidents. Their killers were adult sons in between 67% and 87% of incidents. Several significant differences emerged with respect to age, involvement in multiple offender incidents, and weapon use. Stepmothers and their stepchildren, relative to mothers and their offspring, were significantly younger. Sixty-four percent of stepchildren, compared with 35% of biological children, were under age 25 at the time of their arrest for murder. A higher percentage of juveniles than adult killers was involved in multiple offender (MO) incidents involving mothers. Relative to their male counterparts, higher percentages of female juveniles were involved in MO incidents involving the deaths of mothers and stepmothers. A higher proportion of female adults, relative to their male counterparts, were involved in MO matricide incidents. Offenders who killed stepmothers, relative to those who killed mothers, were significantly more likely to use guns. Juvenile matricide offenders were significantly more likely to use firearms than their adult counterparts. Possible reasons for the differences are discussed in the conclusion.

Weapons used in serious violence against a parent: retrospective comparative register study

AIMS

Our aim was to compare the weapons used in lethal or potentially lethal violence against parents according to the age (adolescent vs. adult) of the offender and victim (mother vs. father) of the offence.

METHOD

All forensic psychiatric examination statements of male offenders who had offended violently against one of their parents during 1973-2004 in Finland (n=192) were reviewed retrospectively. Data on the weapons used by adolescent and adult offenders in relation to the sex of the victim, mental disorder, criminal responsibility and intelligence were gathered.

RESULTS

In the whole sample, sharp-edged weapons were the most commonly used weapons. Firearms were more commonly used in offences against fathers (i.e. patricidal offences) than against mothers (i.e. matricidal offences). Adolescent offenders were more likely to use firearms than adult offenders in violent acts against a parent. Among personality-disordered subjects, patricidal offenders used firearms more commonly than did matricidal offenders. Homicidal matricidal offenders had higher full-scale and verbal IQ scores as compared to homicidal patricidal offenders. The matricidal offenders using firearms were shown to be more intelligent as measured by full-scale and verbal scale IQs than the patricidal offenders using firearms.

CONCLUSIONS

Consistent with the physical strength hypothesis, firearms are used more often in lethal or potentially lethal violence against parents by adolescents than by adults in Finland. As firearms legislation in Finland is currently under reform the study findings suggest that restriction of gun availability may have an influence on intrafamilial homicides, particularly those committed by adolescents.

Personality disorder and criminal behaviour: what is the nature of the relationship?

PURPOSE OF REVIEW

There is a well established association between personality disorder and offending but the nature of the relationship is less well understood. We reviewed the recent literature on personality disorder and offending, picking out studies that examined the relationship between the two.

RECENT FINDINGS

Cluster A, B and C personality disorders are each associated with different types of offences. Although rates of personality disorder are high in all serious offenders, the role played by personality disorder may be greater in some offences than others, for example, in rapists compared with child molesters, men who kill their fathers rather than their mothers, men who kill their children compared with mothers who kill their children; and in less severe stalking behaviour compared with those who get convictions. Three articles suggested frameworks for understanding how personality disorder may interact with other factors to contribute to offending.

SUMMARY

Frameworks that integrate personality traits; comorbid problems such as substance misuse, mood disorders and attention deficit hyperactivity disorder (ADHD) symptoms; motivation for offending; maladaptive cognitions; beliefs and attitudes; anger and arousal; and situational factors are helpful when considering risk assessment, risk management and treatment. More empirical research is needed to test these theories.
