Abstract
Neurobiology of female homicide perpetrators is not well understood. Data from private interviews and examinations of females were re-analyzed comparing those who committed homicide (n = 9); other violent crimes, no known homicide (n = 51); nonviolent crimes, no known violent convictions (n = 49); and noncriminals (n = 12). Homicide perpetrators suffered the most childhood sexual abuse (CSA); most recent abuse; had the most neurological histories, mainly traumatic brain injuries (TBIs); most health care access for abuse-related injuries; lowest AM and PM salivary cortisol; and greatest proportion who committed crime under the influence of alcohol. Only CSA, years since last abuse, TBI, neurological histories, and health care access for abuse-related injuries were significant. Those who committed homicide under the influence of alcohol suffered the most recent abuse and had the lowest AM cortisol and flattest diurnal cortisol slope (DCS) compared with others; though the n precludes determining significance. Amount of time since last abuse, AM cortisol and DCS progressively decreased as crime severity increased; other variables progressively increased as crime severity increased. These preliminary findings suggest that low AM cortisol, flat DCS, greater CSA frequency and severity, recent abuse, TBIs, and health care access for abuse-related injuries could be risk factors for females committing homicide. Further study is needed due to the small n of homicide perpetrators. Abuse victims may be at greater risk for alcohol use and cortisol dysregulation associated with perpetrating violence, especially homicide. Frontal lobe damage from TBIs may decrease ability to control behaviors associated with emotions from the limbic system. Health care providers released these women when their abuse-related injuries were not life-threatening; yet, they were life-threatening for victims of their subsequent homicides. Females accessing health care for abuse-related injuries present a critical opportunity for violent crime prevention interventions.

Abstract
Empirical research pertaining to sentencing of homicide offenders has been restricted almost exclusively to samples of male offenders in the United States. To fill this void in international research and to explore questions regarding the treatment of female homicide offenders further, we examined the extent to which victim-offender relationships and motives independently affect the length of sentences imposed by analyzing a nationally representative sample of female offenders adjudicated guilty of homicide in South Korea, over the period 1986-2013. In contrast to previous studies conducted in Canada, the Netherlands, and the United States, the current study found that the victim-offender relationship has no affect on sentence lengths. Rather, the most significant predictor for the sentence lengths of the female homicide offenders was the motive for killing. We discuss future directions for international comparative research on the roles of victim-offender relationships and motives in sentencing outcomes of female offenders.

Abstract
Although studies have described the incidence and epidemiology of adolescent homicide victimization in South Africa, little is known about the situational contexts in which they occur. This study aimed to describe the victim, offender, and event characteristics of adolescent homicide and to generate a typology based on the particular types of situational contexts associated with adolescent homicide in South Africa. Data on homicides among adolescents (15-19 years) that occurred in Johannesburg (South Africa) during the period 2001-2007 were obtained from the National Injury Mortality Surveillance System (NIMSS) and police case records. Of the 195 cases available for analysis, 81% of the victims were male. Most of the offenders were male (90%), comprising of strangers (42%) and friends/acquaintances (37%). Arguments (33%) were the most common precipitating circumstances, followed by revenge (11%), robbery (11%), and acts of vigilantism/retribution for a crime (8%). Through the use of cluster analysis, the study identified three categories of adolescent homicide: (a) male victims killed by strangers during a crime-related event, (b) male victims killed by a friend/acquaintance during an argument, and (c) female victims killed by male offenders. The results can serve to inform the development of tailored and focused strategies for the prevention of adolescent homicide.

Homicides among women in the different Brazilian regions in the last 35 years: an analysis of age-period-birth cohort effects. CIENCIA & SAUDE COLETIVA 2017; 22:2949-2962.

Abstract
The aim of this study is to estimate the effects of age-period-birth cohort (APC) on female homicides. This is an ecological study which analyzed the violence-related death records of women aged 10 years and older, in the Brazilian geographic regions, between 1980 and 2014. Data on mortality were extracted from the Mortality Information System. The trend analysis was conducted using negative binomial regression and APC effects were analyzed using estimable functions. The average mortality rate for the period was 5.13 deaths per 100,000 women, with the highest rates observed in the Central-West (7.98 deaths), followed by the Southeast (4.78 deaths), North (4.77 deaths), Northeast (4.05 deaths) and South (3.82 deaths) regions. All regions presented a decrease in the risk of death in the period from 2010 to 2014, except for the Northeast region (RR = 1.06, 95% CI 1.02 to 1.10). There was a progressive increase in the homicide risk for women born from 1955 to 1959 in all Brazilian regions. Younger women are at higher risk of dying from homicides in all Brazilian geographic regions. The upward trend of homicide mortality rates according to birth cohort was significant and the highest risk was observed in women born between 2000 and 2004.

Abstract
Well-documented differences in the psychology and behavior of men and women have spurred extensive exploration of gender's role within the brain, particularly regarding emotional processing. While neuroanatomical studies clearly show differences between the sexes, the functional effects of these differences are less understood. Neuroimaging studies have shown inconsistent locations and magnitudes of gender differences in brain hemodynamic responses to emotion. To better understand the neurophysiology of these gender differences, we analyzed recordings of single neuron activity in the human brain as subjects of both genders viewed emotional expressions. This study included recordings of single-neuron activity of 14 (6 male) epileptic patients in four brain areas: amygdala (236 neurons), hippocampus (n = 270), anterior cingulate cortex (n = 256), and ventromedial prefrontal cortex (n = 174). Neural activity was recorded while participants viewed a series of avatar male faces portraying positive, negative or neutral expressions. Significant gender differences were found in the left amygdala, where 23% (n = 15∕66) of neurons in men were significantly affected by facial emotion, vs. 8% (n = 6∕76) of neurons in women. A Fisher's exact test comparing the two ratios found a highly significant difference between the two (p < 0.01). These results show specific differences between genders at the single-neuron level in the human amygdala. These differences may reflect gender-based distinctions in evolved capacities for emotional processing and also demonstrate the importance of including subject gender as an independent factor in future studies of emotional processing by single neurons in the human amygdala.

Abstract
Criminal death incidence of women varies between developed and developing countries, and it has become a common public problem in almost every country. We do not have any data about femicide cases published in Turkey until today. In our study, we tried to call attention to femicide cases. In our study, we evaluated 141 cases of female homicides with an interval of 10 years between January 1996 and May 2005, retrospectively. Data retrieved were statistically evaluated using chi-square test. Most of the cases were between 21 and 35 years of age. Spouse murders are usually witnessed during the process of divorce. Establishment of institutions which will ensure the security of women during this period is of paramount importance. If we protect women during divorce and separation proceedings, we can prevent femicide cases. We also think that laws may be strengthened for protecting women who are vulnerable at such times.

Abstract
The aim of our study was to analyze the homicide pattern in the Western suburbs of Paris and its evolution between 1994 and 2008. All autopsy reports regarding homicides from the period January 1, 1994, to December 31, 2008, were retrospectively reviewed. Five hundred eleven homicide cases were selected of 4842 autopsy cases. The following data were recorded: assailants and victims characteristics, crime scene location, homicide motive, cause of death, and victim's postmortem toxicological results. Homicide rate steadily declined over the period at the exception of the number of homicide-suicide per year, which remained constant. Homicide victims remained unidentified after medicolegal investigations in 2% of the cases. Child and elder homicide cases represented, respectively, 10.7% and 8.2% of the cases. Offenders were male in 88% of the cases. Male and female assailants showed distinct homicide patterns: females were involved more frequently in familial quarrel and child abuse. They never killed a stranger and committed homicide exclusively in a private place with a predominance of sharp weapons. Males, in contrast, assaulted almost equally a stranger or an acquaintance, often in a public place with a predominance of firearm. Victim knew the assailant(s) in 57% of the cases. Homicides mostly took place at the residence of the assailant or the victim. Homicide motive was clearly determined in 71% of the cases. Argument was the most common motive in 44% of the cases. Sexual assault was rarely found (10 cases). Gunshot wounds were the most common cause of death (37%), followed by stab wounds (27%), blunt trauma (19%), and asphyxia (13%). A decrease of gunshot wounds as a cause of death was found over the studied period. Alcohol was the most common toxic detected in blood of the victim, in 48.5% of the cases when toxicological results were available. Blood alcohol concentration ranged from 1 to 500 mg/dL with a mean value of 150 mg/dL.

Abstract
BACKGROUND In past years, the female offender population has grown, leading to an increased interest in the characteristics of female offenders. The aim of this study was to assess the prevalence of female violent offending in a Swiss offender population and to compare possible socio-demographic and offense-related gender differences. METHODS Descriptive and bivariate logistic regression analyses were performed for a representative sample of N = 203 violent offenders convicted in Zurich, Switzerland. RESULTS 7.9% (N = 16) of the sample were female. Significant gender differences were found: Female offenders were more likely to be married, less educated, to have suffered from adverse childhood experiences and to be in poor mental health. Female violent offending was less heterogeneous than male violent offending, in fact there were only three types of violent offenses females were convicted for in our sample: One third were convicted of murder, one third for arson and only one woman was convicted of a sex offense. CONCLUSIONS The results of our study point toward a gender-specific theory of female offending, as well as toward the importance of developing models for explaining female criminal behavior, which need to be implemented in treatment plans and intervention strategies regarding female offenders.
