Health care utilization, mental disorders and behavioural disorders among perpetrators of intimate partner homicide in 2000-2016: A registry-based case-control study from Sweden.

Little is known about intimate partner homicide (IPH) perpetrator´s healthcare contacts and mental health problems before the killing. The aim was to compare male and female IPH perpetrators with matched controls from the general population by analysing differences in healthcare utilization and mental and behavioural disorders. This study includes 48 males and 10 females who perpetrated IPH between 2000 and 2016 in the Västra Götaland Region of Sweden. Controls (n = 458) were randomly selected from the general population and matched for sex, birth year and residential area. Data were retrieved from the Swedish National Patient Register and the Western Swedish Healthcare Register. Mental and behavioural disorders were classified according to ICD-10 (F00-F99). The Mann-Whitney U test was used to test for differences in health care utilization and mental and behavioural disorders. Compared to their controls, male perpetrators had more registered contacts with primary care ≤ 30 (p = < .001) and ≤ 365 days (p = .019), respectively, before the homicide; with specialist outpatient care ≤ 30 (p = < .001) and ≤ 365 days (p = < .001), respectively, before the homicide: and with inpatient care ≤ 30 (p = < .001) and ≤ 365 days (p = .024), respectively, before the homicide. Female perpetrators had more specialized outpatient care (p = .040) and inpatient care (p = .003) contacts ≤ 365 days before the homicide, compared to controls. Male perpetrators had at least one mental or behavioral disorder diagnosed in any studied healthcare setting except in inpatient care ≤ 30 days before homicide. Female perpetrators had more mental health disorders diagnosed in specialized outpatient care ≤ 365 days before the homicide (p < .001). Perpetrators had more healthcare contacts and mental disorders one year and one month prior to the homicide compared to their controls. Health care professionals should obtain necessary skills in routinely enquiring about intimate partner violence perpetration.

Homicide perpetrators with psychotic illness found not criminally responsible in Turkiye and Russia: An international comparison.

OBJECTIVE: The primary objective was to conduct a comparative analysis of homicide cases and their perpetrators with psychotic illnesses in samples from Turkiye and Russia to elucidate contextual similarities and differences, and providing novel perspectives to enhance international research in this field. METHOD: This cross-national retrospective study, conducted at forensic psychiatric centers in Istanbul, Turkiye, and Chuvashia, Russia, involved individuals with psychotic illnesses (ICD-10 F20-F29) who were deemed criminally non-responsible for index homicide offenses between December 2012 and December 2022. The sample included 92 Turkish patients and 29 Russian patients who were compared for background, clinical characteristics, and each homicidal act. RESULTS: Binary analyses revealed that Russian subjects were more educated, had more lifetime suicide attempts, longer illness duration, had acquaintances as victims more frequently, higher rates of blunt traumatic homicides, higher rates of intoxication with alcohol or substances, and lower rates of experiencing delusions at the time of the index homicide compared to their Turkish counterparts. Multivariate analyses indicated that more years of education, a greater frequency of lifetime suicide attempts, higher prevalence of intoxication and a lower rate of delusions at the time of the homicide were associated with belonging to the Russian group. CONCLUSION: Despite several similarities, the remarkable differences between the two samples underscore the importance of international research in enhancing our understanding of mental health, homicidal offense and offender characteristics in the sociocultural context.

Interventions for adult survivors of intrafamilial homicide: A review of the literature.

Individuals bereaved by intrafamilial homicide, in which the perpetrator and decedent were both members of the same family, experience an elevated risk for risk for mental health complications. Given the contextual complexity of intrafamilial homicide (IFH) and the negative sequalae this form of loss can engender, psychological interventions may assist survivors with adjustment on a number of fronts. This scoping review therefore addresses an important knowledge gap by summarizing the limited information on interventions specific to intrafamilial homicide survivors. Results failed to identify interventions specific to IFH bereavement, though interventions that may be deemed appropriate are highlighted and described. As such, this scoping review provides a practical synthesis of evidence-based and evidence-informed psychological interventions for traumatic loss that are applicable to and may hold promise for this vulnerable population. Recommendations for future research and best practices with intrafamilial homicide survivors are also discussed.

Drug-facilitated sexual assault followed by femicidal chloroform poisoning and suffocation: A case-report of criminal responsibility.

INTRODUCTION: Criminal responsibility evaluation represents one of the most controversial and debated issues in forensic psychiatry. Although clear procedures have been recommended, little research exists on decision-making process by forensic psychiatrists. We present a case assessing the criminal responsibility of a murderer who committed femicide as a result of chloroform poisoning and suffocation after a drug-facilitated sexual assault. MATERIALS AND METHODS: A.S., a 30-year-old female, was found dead in the home of S.P., a 50-year-old male. S.P. recounted killing A.S. by forced inhalation of chloroform, when the woman had experienced sensory clouding following unintentional ingestion of Zolpidem, a hypnotic agent. A multidisciplinary approach was taken to resolve the case. Autopsy, histological, genetic, and toxicological examinations were performed by a forensic pathologist, while a digital forensic examiner analysed electronic devices. A pool of three forensic psychiatrists and two psychologists was asked to assess the mental state of S.P. at the time of the crime. RESULTS AND CONCLUSIONS: The cause of death of A.S. was identified as a lethal chloroform intoxication in altered consciousness caused by Zolpidem, while homicidal suffocation was also described. Mobile forensics demonstrated that S.P. had videotaped the crime scene, clearly revealing that A.S. had been sexually assaulted by S.P. before dying. Criminal responsibility of S.P. was evaluated through various psychological tests and seven interviews with the accused, each lasting an average of 180 min. Specialists concluded that S.P. could not be exempted from being responsible for the homicide.

[MURDER STEMMING FROM INSANITY: DEMOGRAPHIC, CRIMINAL, PSYCHIATRIC AND FORENSIC CHARACTERISTICS OF THE PERPETRATORS].

INTRODUCTION: Violence among individuals with mental disorders and murder while in a psychotic state have been studied extensively worldwide. AIMS: To examine the socio-demographic, psychiatric, criminal, forensic and other characteristics of people who committed murder in Israel and were not prosecuted for reasons of insanity. This is the largest such study to date conducted in Israel. METHODS: The files (medical and legal documents) of all patients (N=80) hospitalized in the maximum-security division of Sha'ar Menashe Mental Health Center by court order following murder, were examined. RESULTS: Ninety percent of the participants were diagnosed with schizophrenia and 70% had prior psychiatric hospitalizations before committing murder. Most participants had documented substance abuse and previous violence stemming from mental disorders and did not regularly attend psychiatric follow-ups or take medication between hospitalizations. The motives were usually paranoid delusions. The victims were generally known to the killer, usually family members, and most perpetrators remained at the scene after the murder. CONCLUSIONS: Therapeutic sequence and preventive actions should be implemented in the treatment of this high-risk group. DISCUSSION: Findings delineate characteristics of homicide perpetrators stemming from mental disorders, from which a risk group may be described.

Possibly mad? Marital murder in the early twentieth century: a matched-case gender analysis of forensic psychiatric investigations in Sweden.

This study illustrates the impact on forensic psychiatric investigations (FPI) of time-specific scientific theories and moral normative considerations. A comparative historical perspective illustrates historical FPI procedures (i.e. methodology and focus), based on two matched FPI case reports from the 1930s: a man and a woman who had shot their respective spouses. First, in the analysis, a comparison was made between the two cases regarding assessment procedure and focus, applying a gender perspective, and second, stability and change in FPI praxis between the 1930s and the 2020s were identified. Similarities and differences were discussed based on changes in FPI praxis and influence of explanatory models within psychiatry. This can aid understanding of historical bias and indicate current bias and its risks to FPI reliability.

106 Cases of homicide poisoning in China-A retrospective study.

Homicidal poisoning has received limited scholarly attention, despite having recently increased in frequency in China, especially in rural areas, where it causes numerous deaths and disabilities. In this study, the author collected data on 106 cases of homicidal poisoning from 1995 to 2000. Of these cases 105 were found through website established by the Supreme Court of China, and one case was as an exception identified from the internet. There were 46 male perpetrators and 59 female perpetrators. The most common reason male perpetrators poisoned someone was conflict among neighbours (include residents in the same village) (ten cases), and the most common reason female perpetrators did so was an affair (13 cases). Compared with the perpetrators of general homicide, those who poisoned people included a high proportion of female, elderly, and well-educated individuals. This is related to the nonviolent nature of the poisoning, which requires no physical strength. Residents living in rural and urban areas chose poisoning based on convenience. People living in rural areas used pesticides most often, and people in urban areas have greater access to drugs or medications obtained at work or online. In this study, a total of 9.4% of the perpetrators were diagnosed with psychiatric disorders or psychosis. In all, the 106 cases resulted in 58 human deaths. Tetramine and paraquat caused many of the deaths, and this suggests a need for the government to manage and monitor these highly toxic pesticides. These cases are representative of issues in contemporary Chinese society, for example, population mobility, fierce competition.

The murder of the surgeon Antonio Parrozzani and the relationship between sexual disorders and paranoid thinking.

In this study we aimed to describe the relationship between sexual disorders and paranoid thinking describing the historical case of murder of the famous surgeon Antonio Parrozzani and the pathological personality of his murderer. Parrozzani was killed by Francesco Mancini, his patient in the past. Mancini was obsessed by his sexual problems due to hypothetical injuries after an inguinal hernia surgery, made by Parrozzani. Following treatment, the murderer likely lived his surgery as a traumatic event and developed a paranoid thinking against the surgeon, breaking out with the dramatic homicide. Parrozzani's case highlights the strong relationship between paranoia and sexuality, and likewise this relationship can be considered as a prodromic factor for a psychotic onset. Moreover, this case, supported by two psychiatric assessments of murderer, remembers once again the association between violence and paranoia. Therefore, clinicians should take into account the danger of the possible presence of paranoid obsession together with sexual problems, to prevent psychosis onset or violent acts related to paranoid delusions.

Criminal Justice Outcomes of Suicide by Cop Survivors.

The concept of suicide by cop (SbC) is of interest to psychiatrists, law enforcement professionals, lawyers, and citizens. It is a form of provoked homicide arising from a wish to die. Those who attempt SbC experience more mental illness, substance use, and recent trauma than the general population. This article examines those who attempt SbC and survive the encounters. SbC survivors who threaten or harm police or others may be charged with crimes such as weapons possession, aggravated assault, murder or attempted murder of an officer. The formulation of a provocative act, however, frustrates attempts at defenses based on mental state, resulting in few requests for expert testimony. Few data exist on how these individuals fare in court. Appellate cases in which defendants attempted to introduce evidence of SbC illustrate great variability in adjudication. Psychiatric defenses, such as diminished capacity and insanity, are usually inapplicable or unsuccessful because intent and knowledge of wrongfulness are implied in the provocative act. Diversion of SbC defendants into mental health courts is rare because of firearms use against police. The author argues that criminal justice ignores SbC survivors' mental health and recommends application of therapeutic jurisprudence to give full expression of SbC dynamics.

Childhood maltreatment and homicidal ideation among Chinese early adolescents: The serial mediating role of borderline personality features and aggression.

A large body of evidence linked childhood maltreatment (CM) to juvenile violence and delinquent behavior. However, little is known about the association between CM and homicidal ideation in early adolescents. This study aimed to examine that relationship and to explore the serial mediating role of borderline personality features (BPF) and aggression in that relationship in a large sample of early adolescents. A total of 5724 early adolescents (mean age: 13.5 years) were recruited from three middle schools in Anhui Province, China. The participants were invited to complete self-report questionnaires regarding their history of CM, BPF, aggression, and homicidal ideation. Mediation analyses were evaluated using structural equation modeling. A total of 669 participants (11.7%) reported homicidal ideation in the past 6 months. CM victimization was positively associated with homicidal ideation after adjusting for covariates. Furthermore, the serial mediation analysis showed a significant indirect effect of CM on homicidal ideation through BPF and subsequent aggression. Exposure to maltreatment in childhood is likely to manifest BPF and subsequently higher levels of aggression, which in turn are related to increased homicidal ideation. These findings suggest the need for early intervention for BPF and aggression in early adolescents exposed to CM to prevent the development of homicidal ideation.

Matricide and psychiatric evaluation: An update.

Matricide is an infrequent crime that has often raised to the suspicion that the offender could suffer from a pathological mental status. Although it is hard to establish a relationship between mental disorders and specific forms of homicide, several studies suggest that matricide offender frequently suffers from schizophrenia or other psychotic disorders. Aim of the study was to review the literature in order to explore epidemiologic and psychiatric characteristics of matricide offenders with a focus on the cause of death and crime circumstances. According to the PRISMA statement, 16 out of 225 studies were included. Main findings were the following: 80 victims were reported in total, killed by 81 offenders. In one case two brothers were responsible for the matricide. 81.5% of the offenders were young males. The most represented psychiatric pattern of the offenders was schizophrenia and psychotic disorders (43.2%). 6.2% of victims had also psychiatric disorders. Sharp force injuries were the first cause of death (55%), followed by blunt trauma (15%) and asphyxia (15%). In 12% of cases overkilling was also reported. 13.6% of offenders were considered not guilty for reason of insanity while 25.9% of the offenders had diminished criminal responsibility. A case study of a young homicide offender suffering from personality disorder is reported. In this case the victim also suffered from psychiatric disorders and an overkilling occurred as she was stabbed multiple times post-mortem. In a second case of matricide, the victim was dismembered and the human remains were concealed in several plastic bags.

Sociodemographic, psychiatric and criminal characteristics of elderly offenders under evaluation for criminal responsibility in Turkey.

OBJECTIVE: The aim of this study was to examine a sample (n = 150) of elderly offenders to analyse the psychiatric, medical, demographic, criminal and if available neuropsychological test characteristics and criminal responsibility. METHOD: Data were gathered through a retrospective chart review of applicants aged 65 and over who were referred for determination of criminal responsibility from 2014 to 2019 at the Observation Department of Council of Forensic Medicine (Adli Tip Kurumu Baskanligi, Gözlem Ihtisas Dairesi) who were evaluated under inpatient status by law. RESULTS: There were 150 forensic cases aged 65 and over. The majority of the crimes were homicide (25.3%), homicide attempt (10%), and sexual offence (26%). The majority of sexual offence victims were children (34 of 39 cases). The percentages of decisions on criminal liability were as follows: 76% (n = 114) had full criminal liability, 21.3% of them (n = 32) had no criminal liability, 2.7% of them (n = 4) had reduced criminal liability. For the reduced/no criminal liability group, diagnoses were as follows: 37.1% dementia syndromes, 31.4% schizophrenia, 11.5% delusional disorder and 2.8% bipolar disorder manic episode. CONCLUSION: When the findings in our study and current literature data are examined, it is seen that certain crime groups such as murder and attempted murder, and sexual crimes against children are high in elderly forensic psychiatric evaluations.

Profiling Homicides Based on Impulsive or Proactive Natures in Male Schizophrenia Patients.

The main aim of this study was to ascertain whether a relationship existed between the modus operandi and motivation of homicide, clinical characteristics, and psychopathic traits in schizophrenia. Forty-seven male homicide perpetrators with schizophrenia were included in the study. We classified types of homicide perpetrated by the patients as predominantly impulsive (n = 27) or proactive (n = 20) in nature. We also evaluated the psychotic motivation accompanying the homicide. Forty-four (93.6%) of the homicides were psychotically motivated. The victim was a stranger in only 8.5 percent of the homicides. Use of firearms as a killing method was significantly higher in predominantly proactive homicides (30%) compared with impulsive homicides (3.7%). Infidelity delusions were more frequent in proactive homicides than in impulsive homicides. According to regression models, a predominantly proactive homicide was significantly associated with being married, older age at illness onset, killing with firearms, infidelity delusions and a high PCL-R affective facet score in univariate analyses. Multivariate analyses showed a significant association with infidelity delusions and a high PCL-R affective facet score. Our results confirm that certain predispositions, as well as contextual factors, may be associated with the violent subtype of homicidal behavior in perpetrators with schizophrenia.

Partners in crime: A 21-year cohort comparison of people who commit serious crimes together with those who act alone.

BACKGROUND: Perpetrators who act together violently occur frequently in police and media discussions, but are rarely the focus of forensic psychiatric research. AIMS: We aimed to characterise people who act together when committing a serious crime and to map the frequency of such crimes over 21 years in Finland. METHODS: Data for the study were retrieved from the national database of forensic psychiatric examinations for the period 2000-2020, with reports on file for nearly all people charged with serious criminal offences in the country. Index cases were defined as those with two or more perpetrators attacking a single victim; people who acted alone were comparison cases. Sex and age at the time of the crime were extracted together with all diagnoses listed in the reports. RESULTS: Seventy-five multiple perpetrator groups (MPG) were identified, accounting for 165 individuals whose reports were compared with 2494 single-perpetrator (SPR) reports. Most group and solitary offenders were male (87%: 86%, respectively). The index offence was more likely to be homicide among the group perpetrators (mean 1.12) than the solitary offenders (mean 0.83). Proportionately more of the group offenders had personality disorder or substance use disorders (antisocial personality disorder MPG 49%: SPR 32%; any personality disorder MPG 89%: SPR 76%); alcohol (MPG 79%: SPR 69%; cannabis MPG 15%: SPR 9%). By contrast, psychosis was about twice as common among the solitary offenders (MPG 12%; SPR 26%). CONCLUSIONS: The number of group-perpetrated crimes has not increased, according to these Finnish forensic psychiatric report data of 2000-2020, but the relatively high prevalence among them of personality and substance use disorders is a constant. Understanding psychiatric disorders as factors in both leading to and avoiding violent conflicts may help plan new approaches to further diminish group violence.

Suicide by Cop and Civil Liability for Police.

Suicide by cop (SbC) is a variant of victim-precipitated homicide. In SbC, a citizen intent on dying provokes police, often with credible threats of violence. A fatality results in ambiguity about manner of death (homicide versus suicide). Decedents' families may raise claims of civil-rights violations, asserting insufficient restraint by officers. Police officers, when questioned, may justify their actions as reasonable and necessary force. Defendant officers and municipalities are concerned about police safety and adverse economic and public-perception consequences of litigation. This article explores the history and evolution of the SbC phenomenon, examines related civil case law, and reviews the contours of police-citizen interactions in SbC cases. There is potential liability for officers whose actions must be objectively reasonable to prevail in court. Since SbC can be admitted as evidence, there may be an expanded role for forensic psychiatry in distinguishing manner of death. Expert testimony can also aid fact finders in appreciating the decisions of officers faced with ambiguous and threatening situations. The author recommends collaboration between law enforcement and mental health professionals to improve recognition and handling of difficult situations involving persons with mental illness.

Serial sexual murder by juveniles and the role of sexual sadism: An international study.

This is a descriptive study of 21 cases of serial sexual murder by children and adolescents spanning nearly the past century and a half. No earlier cases worldwide were identified. Each of these youth committed two or more sexual homicides prior to age 18. Their psychopathological, psychosocial, crime scene behaviors, and offender-victim relationship characteristics are presented. Additionally, the role of sexual sadism and its measurement using the SADSEX-SH rating scale is addressed. Nearly all of the sample had conduct disorder, a paraphilic disorder, and sadistic fantasies, and two-thirds had sexual sadism disorder. Family dysfunction, serious school problems, and average or above IQ levels were typical. Their modus operandi generally reflected predatory behavior and direct contact methods of killing were most common. Two case reports are provided to illustrate the breadth and complexity of these offenders. Juvenile Serial Sexual Homicide is an extremely rare but persistent phenomenon. Prognostic implications and future research directions are discussed.

Criminal liability and epilepsy: a case report of a postictal attempted homicide from Tunisia.

OBJECTIVE: Patients with epilepsy who have been charged with a serious offense may be referred by the courts for forensic psychiatric examination. A detailed psychiatric and neurological examination is often necessary to assist the courts in making the right decision, as exemplified in the current case presentation. METHOD: The forensic case of a 30-year-old Tunisian male with temporal epilepsy who exhibited an inadequate response to the treatment is presented here. The patient attempted to kill his neighbor after a cluster of seizures, showing apparent postictal aggression. An antiepileptic treatment was introduced a few days after the person's detention and was followed by forensic psychiatric examination, but the latter was not done until three months afterwards. RESULTS: On forensic examination, the patient's thought processes were clear with no evidence of a thought disorder or psychosis. Both medical and psychiatric opinions stated that the attempted homicide was due to a postictal psychosis. The patient was transferred to a psychiatric facility for further management and was found not guilty by reason of insanity. CONCLUSION: This case illustrates the difficulties that experts may encounter in establishing criminal liability after aggressive behavior associated with epilepsy. It highlights shortcomings in Tunisian law (and promptness of forensic psychiatric examination) that should be addressed to ensure fairness of the legal process.

Filicide by mentally ill maternal perpetrators: a longitudinal, retrospective study over 30 years in a single Northern Italy psychiatric-forensic facility.

Characterization of mentally ill maternal perpetrators of filicide assigned to a single psychiatric-forensic facility, including previous access to mental health services. A cross-sectional, retrospective analysis of medical records and legal documentation of maternal filicide patients at a single psychiatric-forensic facility (1990-2021) was performed. Socio-demographic, relationship, psychopathological, and criminological characteristics were collected. Data were compared according to previous perpetrators' access to mental health services or not and access within 1 year prior to filicide or not. All 55 detainees (mean age 34.8 ± 6.2 years) were included. There were 64 victims; 15 (23%) were ≤ 1 year old and most (77%) were single victims. Some mothers had history of violence/abuse (29%), an aggressive parent (45%), and violent relationships with their intimate partner (46%) and were socially isolated (49%). Most crimes were motivated by altruism (53%). Women had attempted suicide in 39% of filicide cases. Previous psychiatric diagnoses were available for 56%; 71% had accessed services for ≤ 1 year. Patients unknown to mental health services were less likely Italian, with children below preschool age and with no history of physical abuse/violence, aggressive parent, or suicide attempts. Patients lost to mental health services (> 1 year) were less likely Italian or assuming psychopharmacological therapy, were in shorter relationships, and were mostly diagnosed with personality disorders. Female perpetrators of filicide are often unknown/lost to mental health services prior to the crime. Multifactorial historical and current characteristics aid in identifying mothers at risk. Communication of the availability of mental health services must be multi-lingual.

Homicides committed by women with mental disorders: A descriptive study conducted in a French secure unit.

Women remain a small minority of homicide offenders and appear to be understudied in the scientific literature. Gender-specific characteristics are however identified by existing studies. The aim of the study was to explore homicides committed by women with mental disorders, by analyzing their sociodemographic, clinical features, and criminological circumstances of the homicide. We conducted a retrospective and descriptive study among all female homicide offenders with mental disorders hospitalized in a French high-secure unit over a 20-year period (n = 30). We found that the female patients we studied were a diverse group in terms of their clinical profiles, backgrounds, and criminological characteristics. Confirming previous studies, we observed an over-representation of young women, unemployed, with a destabilized family situation and history of adverse childhood experiences. Prior self- and hetero-aggressive behavior were frequent. We found a history of suicidal behavior in 40% of cases. Their homicidal acts often occurred impulsively at home, in the evening or at night and were mainly directed toward family members (60%), especially their child(ren) (46.7%), then acquaintances (36.7%), and rarely a stranger. We found symptomatic and diagnostic heterogeneity: schizophrenia (40%), schizoaffective disorder (10%), delusional disorder (6.7%), mood disorders (26.7%), and borderline personality disorder (16.7%). Mood disorders were exclusively unipolar or bipolar depressions, often with psychotic features. The majority of patients had received psychiatric care prior to the act. We identified four subgroups, according to psychopathology and criminal motives: delusional (46.7%), melancholic (20%), homicide-suicide dynamic (16.7%), and impulsive outbursts (16.7%). We consider that further studies are necessary.
