Intimate partner homicide

Fracture variation in survivable versus fatal blunt force trauma associated with intimate partner violence

Intimate partner violence (IPV) is a global human rights issue that affects approximately 25% of women and 10% of men and is the leading cause of homicides of women worldwide. Multiple interventional studies have been conducted to screen for IPV; however, fractures associated with intimate partner homicide (IPH) have not been studied from a forensic anthropological perspective. Therefore, this study uses computed tomography scans of IPH victims (n=33) obtained from the New Mexico Office of the Medical Investigator to 1) classify and quantify perimortem craniofacial blunt force fractures, and 2) compare the IPH-related fractures to those associated with non-lethal IPV using previously published studies. The results indicate that IPH cases presented similarly to non-lethal IPV cases in that they were concentrated on the middle and lower face, but fractures were more frequent in the upper face and cranial vault in IPH cases. While IPH cases showed more fractures, they were not necessarily associated with extensive fracturing, as 75.8% of IPH victims had five or fewer fractures-the most common being comminuted and linear fractures, comprising 93.8% of IPH-related fractures. As IPV is significantly underreported, understanding the nuances of fracture patterns associated with IPH can help to aid holistic forensic investigations.

Intimate partner homicides in Denmark 1992-2016

Intimate partner homicide is one of the most common types of homicide and a significant contributor to domestic homicides worldwide, especially affecting females. We focus on the intimate partner homicides in Denmark during 1992-2016. Though gender identity data was unavailable, sex data from official documents enabled critical analysis. Of the 1417 homicides in the period, 26.5% were intimate partner homicides, i.e., 55.6% of female and 8.9% of male victims. The annual intimate partner homicide rate was 0.28 per 100,000 (0.44 for female victims and 0.12 for male victims), declining at a lower rate than other types of homicide. Most victims of intimate partner homicides were females (79.3%). The demographics of the victims and the characteristics of the homicides were markedly different depending on victim sex. Female victims were killed by more varied methods, with more severe injuries and followed by suicide in 26.5% and with multiple homicide victims in 8.1%.

Examining the Factors that Impact Suicide Following Heterosexual Intimate Partner Homicide: Social Context, Gender Dynamics, and Firearms

Despite a wealth of research on intimate partner homicide, research on intimate partner homicide followed by suicide of the perpetrator is sparse. Existing studies on intimate partner homicide-suicide: tend to be descriptive, not keeping pace with quantitative advances in the epidemiological and social sciences; have yet to examine how context impacts intimate partner homicide-suicide; and are typically limited to male perpetrators, given small localized samples of female-perpetrated intimate partner (homicide and) homicide-suicide. This study uses data on 7584 heterosexual intimate partner homicide and homicide-suicide cases distributed across 2465 places and 42 U.S. states from the National Violent Death Reporting System (2003-2018) to examine the victim and perpetrator characteristics, relationship dynamics, situational factors, and contextual features that influence the likelihood of committing suicide following intimate partner homicide. Hierarchical logistic regression models indicate that victim characteristics that increase the vulnerability to victimization (alcohol and drug use, mental health problems, less than some college education) decrease the odds of committing suicide following intimate partner homicide. Similarly, situational (victim weapon usage, additional perpetrators) and contextual (concentrated disadvantage, residential instability) risk factors decrease the odds of committing suicide following intimate partner homicide. Conversely, impairment of the perpetrator (alcohol use, mental health problems) and a more intimate victim-perpetrator relationship (spousal relationship, caregiver) increases the odds of homicide-suicide. Additionally, results indicate that firearms play an integral part in homicide-suicide as well as in decreasing the gender gap in homicide-suicide. The findings suggest that the internalization of guilt by perpetrators of intimate partner homicide may play a key role in subsequent suicide. Practically, limiting firearm exposure will not only reduce the lethality of intimate partner violence, but will decrease the odds of perpetrator suicide following intimate partner homicide. This is particularly true for female-perpetrated homicide-suicide, which is unlikely to occur without a firearm.

Socio-demographic and psychosocial characteristics of male and female perpetrators in intimate partner homicide: A case-control study from Region Västra Götaland, Sweden

Risk factor studies on male-perpetrated intimate partner homicide (IPH) are often compared with studies on intimate partner violence (IPV) or non-partner homicide perpetrators. This not only excludes female perpetrators, but also fails to take socio-demographic and psychosocial differences between perpetrators and the general population into consideration. The aim of this study was to examine male- and female-perpetrated IPH cases, and to compare socio-demographic factors in IPH perpetrators and in matched controls from the general population. Data were retrieved from preliminary inquiries, court records and national registers for 48 men and 10 women, who were perpetrators of IPH committed in 2000-2016 and residing in Region Västra Götaland, Sweden. The control group consisted of 480 men and 100 women matched for age, sex and residence parish. Logistic regression, yielding odds ratios (OR) with 95% confidence intervals (CI), was performed for male perpetrators and male controls to investigate associations for selected socio-demographic and psychosocial characteristics. This was not performed for females due to the small sample size. Female perpetrators were convicted of murder to a lesser extent than male perpetrators. No woman was sentenced to life imprisonment while five men were. Jealousy and separation were the most common motivational factors for male perpetration while the predominant factor for female perpetrators was subjection to IPV. Statistically significant differences were found between male perpetrators and male controls in unemployment rate (n = 47.9%/20.6%; OR 4.4; 95% CI 2.2-8.6), receiving benefits (n = 20.8%/4.8%; OR 5.2; 95% CI 2.3-11.7) and annual disposable income (n = 43.8%/23.3% low income; OR 5.2; 95% CI 1.9-14.2) one year prior to the crime. Female IPH perpetrators were less educated than female controls (≤ 9-year education 30%/12%) and were more often unemployed (70%/23%) one year before the crime. Male and female IPH perpetrators were socio-economically disadvantaged, compared with controls from the general population.

Characteristics of persons accused of intimate partner homicide amongst forensic psychiatric observations

BACKGROUND

Intimate partner homicide (IPH) is a global public health problem. One study conducted over 66 countries found that 13.5% of all homicides and 38.6% of female homicides were committed by an intimate partner. In South Africa, there were no published studies that examine alleged perpetrators of IPH that were referred for forensic psychiatric observation.

AIM

To describe the profile of accused persons referred for forensic psychiatric observation for a charge of murder or attempted murder of their intimate partners. Certain characteristics were further examined according to the psychiatric observation outcomes.

SETTING

The study was conducted at Sterkfontein Hospital, a forensic psychiatric hospital in Gauteng, South Africa.

METHODS

A retrospective record review of accused persons referred for forensic psychiatric observation for a charge of murder or attempted murder of their intimate partners was conducted. The period of the review was 19 years. The definition of intimate partners included current or former spouses and partners, same-sex partners and rejected suitors.

RESULTS

One hundred and sixty-three files, which included forensic psychiatric reports, were reviewed. The findings related to the profile of accused persons and offence characteristics indicated that: (1) history of violent behaviour is prevalent; (2) homicides mostly occur in private homes; (3) knives and firearms are most often used; (4) infidelity, separation and jealousy are common motives; (5) psychotic disorders, personality disorders and substance use disorders feature prominently. A total of 88% of the sample were found fit to stand trial and 82% were found criminally responsible. Factors significantly associated with being found fit to stand trial and criminally responsible following the forensic psychiatric observation were: male gender, having received a tertiary education, employment prior to the offence, earning a salary of more than R10 000, having no previous psychiatric or medical illness, a positive forensic history, previous intimate partner violence (IPV) perpetration, indicating a motive for the homicide, having no psychiatric illness at the time of the offence which would impact fitness to stand trial and criminal responsibility.Factors significantly associated with being found not fit to stand trial and not criminally responsible following the forensic psychiatric observation were: female gender, having received a primary education, unemployment prior to the offence, having a previous psychiatric or medical illness, no forensic history, no previous IPV perpetration, not indicating a motive for the homicide, having a psychiatric illness at the time of the offence which would impact fitness to stand trial and criminal responsibility.

CONCLUSION

The characteristics highlighted in this study can contribute to the development of risk assessment tools which can be used to identify likely perpetrators of IPH. Other interventions, for example controlling access to knives and firearms, reducing substance abuse and improving mental health services, are also important in the prevention of IPH.

Characteristics of Intimate Partner Homicide in China: Compared With Previous Studies in Other Countries

Advancing towards modernization and urbanization, China is currently witnessing a soaring increase in intimate partner homicide (IPH). The present study sought to explore the characteristics of IPHs in China. Data from 979 judgments of this lethal serious crime were analyzed. In comparison with studies from other parts of the world, this study determined the characteristics of IPHs in China in terms of perpetrators, victims, incidents, and types of intimate relationships. Although the previous theoretical research has given reasonable explanations for IPHs, the relationship between perpetrator and victim is actually a neglected area in the study of IPHs. In this study, we found that the relationship between them played a leading role in understanding IPHs in China.

The Intersection of Firearms and Intimate Partner Homicide in 15 Nations

Intimate partners commit approximately one in three homicides against women worldwide. Little is known about situational factors that contribute to intimate partner homicides (IPH) and how they may differ across nations. This article provides a cross-national exploration of one situational factor, the use of firearms in the commission of homicides, and considers whether nations have laws designed specifically to keep firearms out of the hands of batterers. We conducted a systematic search of peer-reviewed research and governmental and nongovernmental reports for data on weapon use in IPH. Data were located for 15 nations and subnational areas, which varied from firearms being involved in no IPHs in Fiji to 59% in Antalya, Turkey. Seven nations have legislation that addresses gun ownership as it relates to those who have been charged with, convicted of, or show a propensity toward the commission of intimate partner violence. These laws vary in whether domestic violence is a factor considered in whether to allow firearm ownership or whether it served to disqualify ownership. Due to the small number of nations for which data on weapon use in IPH were located, we did not conduct any hypothesis testing. There is a need for detailed homicide surveillance systems among nations so that researchers can explore the epidemiology of these homicides and ultimately identify opportunities for intervention.

A multi-state examination of the victims of fatal adolescent intimate partner violence, 2011-2015

Background:

Fatal intimate partner violence occurs among adolescents, which is often when first exposure to intimate partner violence occurs in the United States. However, research mainly examines intimate partner violence-related fatalities between adult intimate partners. Such findings document that non-intimate partners, corollary victims, are at risk for violence during intimate partner violence incidents, as well. Research examining fatal intimate partner violence among adolescents is scant. This study informs public health of the extent and circumstances of fatal adolescent intimate partner violence by quantifying the burden across a five-year span; describing fatal victims by demographics and precipitating circumstances; and examining differences by victim type.

Methods:

This study used data from 17 states of the United States in the National Violent Death Reporting System to examine fatal intimate partner violence-related incidents involving at least one ado-lescent intimate partner (15-19 years of age) from 2011-2015. IPV-related death cases were guided by the intimate partner violence surveillance criteria prescribed by Centers for Disease Control and Prevention. Decedents were subdivided into intimate partner victims, perpetrator victims, and corollary victims. Victims were described by demographics, victim descriptors, and precipitating circumstances of death. Annual trends and descriptive statistics were calculated.

Results:

There were 93 intimate partner violence-related fatal incidents among adolescents with 116 decedents. A firearm was the predominant weapon. Crises, arguments, jealousy, and physical fights were common precipitating circumstances. Corollary victims represented 18% of all victims, 65% were intimate partner victims, and 17% perpetrator victims. Corollary victims were primarily linked to the suspect by other intimate partners, and friends and acquaintances.

Conclusions:

Intimate partner violence is a preventable public health problem. This study documents that intimate partner violence among adolescents can result in deaths of intimate partners and corollary victims. Effective prevention should begin in early adolescence and incorporate shared and protective risk factors to have the greatest impact on adolescent IPV.

Homicide in Denmark 1992-2016

We present the findings for homicides in Denmark for 1992–2016. There were 1417 homicide victims (62.2% males, 37.8% females) that were killed in 1321 homicide events. The most common methods were sharp force trauma (33.2%), gunshot (22.2%), blunt force trauma (21.9%) and asphyxia (17.6%), and all methods exhibited a reduction during the study period. The homicide rate was 1.05 per 100,000, 1.32 per 100,000 for males, and 0.78 per 100,000 for females.

Domestic homicides were the largest main group of homicides (76.5% of all female victims vs. 23.6% of male victims). Of the non-domestic homicides, 84.2% of victims were male, the largest group being in the setting of nightlife and/or intoxication. Most female victims (76.9%) were killed by someone in their family, while the largest share of male victims (34.5%) were killed by a friend or acquaintance. The offenders were males in 87.9% of all homicides.

Religiosity,Conservatism, and Acceptability of Anti-Female Spousal Violence in Egypt

Physical violence directed at women is a significant social and public health problem globally. Initial studies tended to concentrate on developed countries, often relying on clinical or shelter samples to assess incidence and prevalence. Although prevalence is critical, reducing or eliminating some problems also requires comprehension of cultural norms and expectations. In the present study, we use a population-based survey to understand factors contributing to attitudes in support of physical violence against married women. More specifically, the aim of the study was to investigate the impact of religiosity and social conservatism on acceptability of physical spousal violence in the Arab Republic of Egypt. Data utilized were derived from Wave 6 of the World Values Survey conducted in 2013. Bivariate and multivariate regression models were fitted to the data. It was found that religiosity was significantly associated with physical spousal violence ( b = -123, t = -4.480). Individuals who attended more often were less apt to accept physical spousal violence. Social conservatism was strongly tied to approval of physical violence ( b = .368, t = -4.115). It was concluded that culturally biased and patriarchal attitudes that devalue women in Egypt, instead of religion, may be the underlying reason for spousal abuse. It was also concluded that improving higher education for both men and women would reduce physical spousal violence.

Axe injury pattern in homicide

Chop or slash wounds are produced by sharp-edged tools such as an axe, or a machete. This paper presents a case of a violent death of a 57 year-old-man. Autopsy revealed deformation of the right side of the head. A total of 23 slash, stab and cut wounds as well as contused lacerations were identified on the scalp as well as the face and the neck. In addition, superficial abrasions and bruises were identified on the skin. The immediate cause of death was due to extensive brain contusion following fragmentation of the neurocranium. The injuries resulting in the death of the victim were sustained during an assault on the head with an axe, which was used both as a slashing tool and a blunt instrument.

Homicide in Greenland 1985-2010

PURPOSE

Homicide in Greenland has not often been investigated. The latest published study documented a dramatic rise in the homicide rate from around 1/100,000 inhabitants to more than 23/100,000 inhabitants from 1946 to 1984. The aim of our study was to characterize homicides in Greenland from 1985 to 2010 and to compare trends during this period with those in previous studies and with homicide characteristics in Denmark, northern Europe, and other Arctic regions.

METHODS

We identified a total of 281 homicides by legal definition and 194 by medical definition, the latter from the years 1990 to 2010. We procured case files for a total of 129 victims (71 male, 58 female) and 117 perpetrators (85 male, 32 female).

RESULTS

We identified an overall decrease in the homicide rate during our study period. The decrease in the medical homicide rate was significant (p = 0.007). The homicide rate ranged from 25/100,000 inhabitants to 13/100,000 inhabitants when results were grouped within 5-year periods. There were significantly more male perpetrators (p < 0.001) and among female perpetrators there were significantly more male victims (p < 0.001). Sharp force and gunshot-related killings dominated homicide methods (41 and 29% respectively), with sharp force deaths increasing throughout the investigation period. Altercations were the main motive (49%). Alcohol-related homicides decreased in our study period.

CONCLUSIONS

While the Greenlandic homicide rate has decreased, it is markedly higher compared to that seen in Denmark and northern Europe. However, it resembles the rate seen in the rest of the Arctic. Liberal gun laws do not affect the proportion of gun-related killings. Despite the high homicide rate, women account for almost half the victims.

Domestic Homicide: Neuropsychological Profiles of Murderers Who Kill Family Members and Intimate Partners

Domestic homicide is the most extreme form of domestic violence and one of the most common types of homicide. The objective was to examine differences between spontaneous domestic homicide and nondomestic homicide offenders regarding demographics, psychiatric history, crime characteristics, and neuropsychological status, utilizing neuropsychological test data from forensic examinations of 153 murderers. Using standard crime classification criteria, 33% committed spontaneous domestic homicides (SDH) and 61% committed nondomestic homicides (NDH). SDH offenders were more likely to manifest psychotic disorders, but less likely to be diagnosed with antisocial personality disorder or to have prior felony convictions. SDH offenders manifested significantly worse neuropsychological impairments than NDH offenders. The mean number of victims was lower for the SDH than the NDH group and only 14% of SDH offenders used a firearm, whereas 59% of NDH offenders used a firearm. These findings corroborate the notion that spontaneous domestic homicide may represent a discernible criminological phenotype.

Intimate partner violence against women in Spain: A medico-legal and criminological study

Intimate partner violence (IPV) is a significant worldwide problem whose magnitude and risk factors vary across different settings and cultures. Nowadays, it is a priority to improve the knowledge on this issue in order to formulate better evidence-based policy responses. This study aims to contribute to a better understanding of non-fatal IPV against women in Spain. A retrospective analysis of IPV cases with a final judicial decision was carried out. The period under study extended from January 2005 to December 2012, with a total of 582 files included in the investigation. Most IPV victims were young adult women of Spanish origin, either married or single, with children, unemployed and with a low family income level. The majority of alleged perpetrators were young adults, employed, with a middle-low income level, a history of alcohol consumption/abuse, but no criminal records. Most victims had previous history of IPV, were engaged in a long-term relationship with their abuser and lived with him at the time of assault. The combination of psychological and physical abuse was the most frequent form of violence. The most common mechanisms of assault consisted in minor acts of physical violence, which resulted in mild injuries, most of them in the upper limbs and face. Nearly half of women sought medical care, but physician's injury report was only made in about a quarter of these cases, even though it is mandatory for health professionals. The majority of criminal proceedings were initiated by the victim's report and ended in conviction, most of them being considered occasional mistreatment. This study confirms the heterogeneity of the phenomenon of intimate partner violence. The importance of adopting standard IPV concepts and promoting the recognition and assessment of this form of violence amongst health care professionals, criminal investigators and forensic personnel is emphasized.

Fatal intimate partner violence against women in Portugal: a forensic medical national study

Intimate partner violence (IPV) is an important cause of women's health and socio-familial severe problems, the most extreme being the victims' homicide. This is the first nationwide Portuguese autopsy-based and judicial-proven study about female intimate partner homicide. At least 62 women over 15 years old were killed by current or former men-intimate partners, corresponding to an IPV-related female mortality rate of 0.44/100.000 women; intimate partner violence was the reason of homicide in 60.8% of all autopsied women. The typical Portuguese victim showed to be a young adult woman, employed, killed by a current husband in a long-term relationship, usually with children in common and with a history of previous IPV. The typical Portuguese perpetrator showed to be older than the victim, employed, owning a firearm and without criminal records. At the time of the fatal event 59.7% of the relationships were current. In 57.9% of the former relationships women were killed during the 1st year after its terminus. Near half of the perpetrators attempted or committed suicide afterward. Most women were killed by gunshot wounds (45.2%), especially in the thorax (48.4%), with multiple fatal injuries; 56.5% also presented non-fatal injuries. The detection of prior IPV and the risk evaluation seems to be fundamental to decrease these fatal outcomes, but also, the prevention of perpetrators' alcohol abuse and carrying weapons. This work emphasizes the need to deepen the research on this issue, aiming to contribute to prevent both fatal and non-fatal IPV-related cases.

Gender-specific risk factors for intimate partner homicide--a nationwide register-based study

The present study examined gender differences in intimate partner homicide (IPH) and offender characteristics with the focus on putative gender-specific risk factors in a nationwide consecutive sample of homicide offenders. Data on all offenders (N = 642; 91 females, 551 males) convicted of homicide and subjected to a forensic psychiatric examination in Finland were obtained for the years 1995 and 2004. IPH offenders, 39 female and 106 male, were compared for risk factors with female and male offenders whose victims were not spouses. The forensic psychiatric examination reports were retrospectively analyzed, and the Hare Psychopathy Checklist-Revised (PCL-R) was rated. Significant gender differences were found in four risk factors: employment, intoxication of victim, self-defense, and quarrel, mostly related to alcohol as a factor of the offense. The findings support the notion that female IPH is linked to defensive reactions resulting from prior abuse, and that IPH offenders resemble the general population more than offenders of other types of homicide.
