Motives for maternal filicide: results from a study with female forensic patients

The objective of this study was to examine different motivational factors, leading mothers to commit neonaticidal, infanticidal or filicidal acts. This study was based on data gathered through a retrospective chart review of all filicidal women admitted to the Mid-Hudson Forensic Psychiatric Hospital in New York State (MHFPC) between 1976 and 2000 (n=57). Because our sample was drawn from MHFPC records it excludes filicidal mothers who went directly to prison. Our women were either found not competent to stand trial, or found not guilty by reason of insanity, or were convicted offenders who were seriously mentally ill and were not sent to prison. Fourteen percent committed neonaticide, meaning that they killed their child within the first day of its life; 21% killed the child after the first day but before it reached its first birthday (infanticide); and 65% committed filicide by murdering a child older than one. Two groups of women could be identified as having different motivational profiles: The neonaticidal mothers were mostly troubled by psychosis and social problems while the filicidal women were defined as severely depressed, with a history of self-directed violence and a high rate of suicide attempts following the filicidal offense.     

Filicide, attempted filicide, and psychotic disorders

The objective of the study was to describe and discuss the cases of two women who faced criminal charges, one for attempting to murder her three children and the other for killing her 1-year-old boy. After a forensic psychiatric assessment of their level of criminal responsibility, these patients were considered not guilty by reason of insanity and were committed to forensic mental hospitals. These two patients received a diagnosis of paranoid schizophrenia, according to the DSM-IV-TR criteria. In both cases, psychotic symptoms were present before the manifestation of violent behavior, in the form of persecutory delusions, auditory hallucinations, and pathological impulsivity. The investigation into cases of filicide may contribute powerfully to expand our understanding of motivational factors underlying this phenomenon and enhance the odds for effective prevention.     

Murder Followed by Suicide: Filicide–Suicide Mothers in Italy from 1992 to 2010

The international literature shows that in 40–50% of the cases, homicides–suicides involving children under the age of 10 are committed by mothers. Here, we report some results on homicides–suicides, in the mother–child relationship, occurred in Italy between 1992 and 2010. We examined 36 cases of filicide–suicide mothers by consulting the archives of RAI, daily newspapers, and the ANSA news agency. We focused on: mothers and children's age, place of residence, date and place of the murder, number and sex of the murdered children, and modality of the homicide–suicide. At the time of the homicide–suicide, the average age of mothers was 35.4. The number of children killed by each mother was one, except in seven cases. All the women had underestimated psychopathological disorders and only six women were regularly treated. The dynamics and characteristics of the events were much more similar to suicides than homicides, so we can consider them as “extensive suicides.”     

Fathers Who Kill Their Children: An Analysis of the Literature

Abstract:  Roughly half of filicidal acts are committed by fathers, though the majority of the literature focuses on maternal filicide. This paper reviews the existing literature on paternal filicide with the goal of identifying characteristics common among these fathers. Fathers who killed their children were, on average, in their mid thirties. The mean age of their victims was five. They may have multiple victims. Sons and daughters were killed in equal numbers. Reasons included death related to abuse, mental illness (including psychosis and depression), and revenge against a spouse. The method often involved wounding violence. Suicide following the act occurred frequently. After being tried for their crimes, filicidal fathers were more frequently incarcerated than hospitalized. Given the range of those capable of this act, mental health professionals must be alert to the possibility of filicide in a variety of fathers. Considering this risk, clinicians should inquire about thoughts of harming children, partners, and themselves.

Maternal Filicide in Turkey

Filicide occurs in every socioeconomic stratum around the world. This study was conducted to evaluate motives, psychopathological aspects, and socio-demographic factors of 74 filicide cases of women in Turkey. Mean age of mothers, most of whom committed infanticide, was 26 years, and breakdown of criminal offenses are as follows: “to get rid of unwanted babies” (24.3%), “acute psychotic-type filicide” (21.6%), “fatal child abuse and neglect” (17.6%), “to get revenge” (12.2%), “protect the lonely child from the harm and badness after suicide” (10.8%), and “pity” (9.5%) motives. Results showed that maternal filicide cannot be reduced to only mental instability or environmental factors and indicates deficiencies in the capacity of the mothers' role in connecting with their child and with parenting skills. Finally, with regard to defendants' motives, similar factors that contribute to committing maternal filicide should be considered while making an assessment of the data and determining employee risk groups.

Clinical presentation of malingerers diagnosed by experienced forensic psychologists

Little is known about the incidence of malingering or the diagnostic criteria for malingering employed by forensic clinical psychologists conducting pretrial evaluations for the criminal justice system. The clinical presentations of 39 criminal defendants diagnosed as malingering psychotic symptoms were contrasted with 25 defendants diagnosed as genuinely psychotic. The incidence of diagnosed malingering was 8% in a series of 314 consecutive evaluations. Malingerers differed from psychotics on 14 of 24 clinical presentation variables, including measures of general presentation, affect, hallucinations, delusions, and formal thought disorder. Results indicate consistent clinical features associated with the diagnosis of malingered psychosis.A summary of this study was presented at the 1988 Annual Convention of the American Psychological Association in Atlanta, Georgia. We very much appreciate the contribution made by the six forensic clinical psychologists at the Michigan Center for Forensic Psychiatry who volunteered to participate in this study.     

Intra-familial child homicide in Finland 1970-1994: incidence, causes of death and demographic characteristics

The purpose of this study was to investigate all child homicides for the 25-year period, 1970-1994 in Finland and to analyse the specific characteristics of the filicide cases. A total of 292 child homicides occurred during this period. In 201 (69%) cases the offender was a parent or a stepparent of the child. Altogether, 173 (59%) of the victims were boys and 119 (41%) were girls. For the closer examination of the filicide cases we excluded the neonaticide and homicide-suicide cases. Consequently, we report on 70 filicide victims. Of these victims, 42 (60%) were boys and 28 (40%) were girls. Twenty six (37%) of the children were killed before the age of 1 year and 53 (79%) before the age of 5 years. The offender was the mother in 43 (61%) cases and the father or the stepfather in 26 (37%) cases. The victims of the mothers were younger than those of the fathers. The most frequent causes of death were head injuries, drowning and suffocation. The most common means of assault were battering, drowning and strangulation. One in two of the fatally battered children had a documented history of previous abuse.     

Diagnostic values of polysomnography in forensic medicine

A man accused of a first-degree murder of a two-year-old girl claimed that he had not been conscious during the time of the alleged murder. The possibility that he may have committed the crime while "sleepwalking" was raised. The forensic psychiatrist looked to the sleep disorders facility to conduct polysomnographic investigation of the accused in order to investigate the possibility that he had a parasomnia. Overnight sleep recordings with video surveillance carried out for two consecutive nights showed no evidence of parasomnia. On the basis of the full assessment, the final report of the forensic psychiatrist did not support a legal defense of non-insane automatism and "sleepwalking" was withdrawn as a possible defense by the lawyer of the accused.     

Perceptions and experiences of people with mental illness regarding their interactions with police

This study examined the perceptions and lived experiences of people with mental illness in relation to their interactions with the police. A community-based participatory research approach was used and a procedural justice theoretical perspective guided the study. In-depth, semi-structured interviews were conducted by peer researchers with 60 people with mental illness who had interacted with the police and were living in Metro Vancouver, Canada. Among the study participants, contact with the police was frequent and occurred under a diverse range of circumstances. The majority of participants perceived being treated in a procedurally just manner by the police officer(s) who were involved in their most recent interaction. Almost three-quarters (n = 43, 72%) of participants were generally satisfied with how the police officer(s) had handled their most recent interaction. The slight majority of participants (n = 30, 51%) rated their previous contacts with the police as a positive experience overall, with 32% (n = 19) indicating that their previous interactions with the police were negative life experiences. The findings paint a more balanced picture than that which is often portrayed by the media. Emphasizing a procedural justice framework for police handling of situations involving people with mental illness is a vital step toward improving how these interactions are experienced and perceived.     

Physician crimes and criminals. The historical and forensic aspects

The physician, like any other human being, is subject to emotional problems, greed, jealousy, and instability of an individual under stress as well as mental disease which may all bring out improper behavior or criminal activity. Over the last two centuries, there have been instances where physicians have committed deliberate acts of murder on wives, relatives, patients, and others. Their motivation has ranged from ridding themselves of a nagging wife or for insurance and inheritance gains to insane acts. The methods used have usually been associated with poisons and drugs, of which the physician may have great familiarity. The frequency of physician-involved murders seems to have increased in the past two decades with several sensational cases being the topics of media coverage and further review in books and visual media, including television and the movies. The investigation of these cases may be very difficult, especially when a drug may be given to a victim which could cause severe problems after small amounts are given. The detection of death as being a murder may be the first problem faced, the demonstration of the fatal agent in the body in the next problem, and probably the most difficult is finding a suspect with the medication in his or her possession or paraphenalia for injecting such as a syringe and needle. The stealth and cunning of the murderer may further complicate the picture for the investigator as well as the reputation of the physician in the community, which is often above reproach so that the public has to be convinced of the actual involvement of the suspect.

Intimate partner violence within a cohort of Pacific mothers living in New Zealand

Maternal reports of intimate partner violence (IPV) were obtained from a cohort of Pacific mothers living in New Zealand. The Conflict Tactics Scale was completed by 1,095 women who had given birth in the past 12 months, and who were married or living with a partner as married. The 12-month prevalence of "victimization" through verbal aggression was 77%, 21% for "minor" physical violence, and 11% for "severe" physical violence. The 12-month prevalence of "perpetration" of verbal aggression against a partner was 90%, 35% for "minor" physical violence, and 19% for "severe" violence towards their partner. The experience of social inequality and acculturation are associated with IPV, albeit differentially across the experience of victimization and perpetration. Factors significantly associated with victimization are ethnicity, maternal education, social marital status and household income. Factors significantly associated with perpetration are ethnicity, cultural alignment, maternal birthplace and alcohol consumption since the birth of the child.     

Effects of psychopathy and violence risk testimony on mock juror perceptions of dangerousness in a capital murder trial

The recent introduction of the Psychopathy Checklist-Revised (PCL-R) into the sentencing phase of capital murder trials has heightened concerns about the potentially prejudicial impact of such information on jurors, who might give disproportionate weight to this diagnosis when determining whether a defendant is a “continuing threat to society”. To investigate this issue, 238 undergraduates read a case summary based on US v. Barnette ( ), in which prosecution testimony was presented regarding the presence of a mental disorder (psychopathy, psychosis, or no disorder). Compared to the “no disorder” condition, participants rated psychopathic defendants as more likely to be violent in the future, even though testimony related to level of risk (high or low) was held constant. The difference in perceived dangerousness across the psychopathy and no disorder groups was particularly pronounced when the experts described the defendant as being at low risk. A similar pattern of effects was noted for the psychosis condition, suggesting that the impact of mental disorder testimony on perceptions of dangerousness may not necessarily be specific to the PCL-R.     

The presence of low IQ and mental retardation among murder defendants referred for pretrial evaluation

After an overview of definitions of mental retardation and recent case law regarding mental retardation and the death penalty, this paper presents a study of factors associated with a mental retardation (MR) diagnosis among murder defendants. Subjects with a full-scale IQ< or =70 (n=42) were compared with other pretrial murder defendants (n=228) referred for forensic evaluation over a 5-year period. Subjects with an IQ< or =70 who were diagnosed with MR were compared with subjects with an IQ< or =70 who did not receive this diagnosis. Female murder defendants were more likely to receive a diagnosis of MR (p=0.03). MR was also more commonly diagnosed in subjects with an Axis I cognitive disorder (p=0.018). Having an IQ< or =70 was more common in subjects with a psychotic and substance use disorder (p=0.03) and did not necessarily lead to a diagnosis of MR in this subgroup. Implications for diagnosing MR among murder defendants are discussed.     

The Relationship Between Mental Disorders and Types of Crime in Inmates in a Brazilian Prison

This cross‐sectional study conducted in prisons in the city of Salvador, Bahia, Brazil, investigated the association between the presence of psychiatric disorders in 462 prisoners and the types of crimes committed by them. Psychiatric diagnosis was obtained by means of the Brazilian Portuguese version of the Mini‐International Neuropsychiatric Interview. A statistically significant association was found between some psychiatric disorders and specific groups of crime: lifelong substance addiction with sex crimes and homicide; antisocial personality disorder with robbery and with kidnapping and extortion; borderline personality disorder with sex crimes; and lifelong alcohol addiction with fraud and conspiracy and with armed robbery and murder. It was concluded that the mental disorders considered more severe (psychosis and bipolar disorder) were not associated with violent crimes, suggesting that the severity of the psychotic disorder may be the factor that has caused psychosis to be associated with violent crimes in previous studies.     

Homicide by a Forensic Female Sample in Brazil: A Preliminary Study

The objective of the study was to evaluate the mental status of all women (n = 14) who were acquitted by reason of insanity of charges of murder or attempted murder and committed to a forensic psychiatric hospital in the state of Rio de Janeiro, Brazil. All cases were retrospectively examined, including medical files, technical records, and forensic experts' official reports. A conclusive psychiatric diagnosis was established using the Structured Clinical Interview for DSM‐IV Axis I and II Disorders and clinical and forensic records. The most common diagnosis was schizophrenia/schizoaffective disorders (n = 8; 57.3%). Most victims (n = 12; 75%) were close relatives of the patients. We found that 43% (n = 6) of the patients had a previous history of violent behavior. According to the initial psychiatric forensic evaluation, 5 patients (35.7%) had psychotic symptoms. It is expected that a growing understanding of motivational factors underlying homicidal behavior in mentally disturbed female offenders may further the implementation of effective preventive and therapeutic interventions.     

The impact of gender roles on verdicts and sentences in cases of filicide

Although mothers and fathers are equally likely to kill their children, maternal filicide cases tend to draw more media coverage and community outrage. While traditional gender role expectations appear to contribute to the community response that follows a report of filicide – and influence media representations – little is known about the offenders’ treatment in the criminal justice system. Drawing on theorizing within gender studies, this article examines relationships between traditional gender role expectations and court case outcomes in cases of maternal and paternal filicide. Findings indicate that both verdicts and sentences in these cases vary by gender and that, for female offenders, the differential treatment is related to how well they appear to fit traditional gender roles.     

Hair as a source of forensic evidence in murder investigations

Obtaining palynological and other botanical evidence from murder victims is becoming part of routine mortuary protocol in the United Kingdom. Forensic pathologists are often keen to cooperate in the collection of classes of material that have, in the past, been considered to be of little importance in criminal investigation. Work over the last eight years has demonstrated the great value in scrutinising cadavers for the presence of plant material and/or soil stains. Macroscopic plant remains and palynomorphs (pollen, spores and other microscopic entities) retrieved from skin and hair have allowed the differentiation of murder scenes from places of eventual deposition. Furthermore, although the opportunity has not yet presented itself, obtaining palynological evidence from the hair of suspects is feasible. During an offence, the offender might have had physical contact with foliage or the ground. Pollen and spore assemblages picked up by hair during that activity might provide forensic evidence for contact. Brief details of some aspects of case histories are presented to demonstrate the value of sampling cadavers. One case has been through the courts while the other is ongoing and, therefore, cannot be identified.
