[Homicides in southern South American cities: educational inequalities and economic fluctuations]. / Homicidios en ciudades del sur de Sudamérica: desigualdades educativas y fluctuaciones económicas.

Information on how economic fluctuations affect educational inequalities in homicides in Latin America is scarce. This study aimed to: (a) analyze the temporal variations of educational inequalities related to homicide mortality and (b) compare these inequalities between years of economic growth and recession in southern South America cities from 2000 to 2019. Data from seven urban areas in three countries in the Southern Cone of South America were used: Mendoza and Rosario (Argentina); Belo Horizonte, Curitiba, Rio de Janeiro, and São Paulo (Brazil); and Santiago (Chile). Poisson models were estimated by using age, sex, city of residence, year of economic growth or recession, and schooling level as explanatory variables. Results showed significant differences in the temporal evolution of homicide rates in the seven cities, although populations with a low schooling level always showed the most vulnerability. The four Brazilian cities, analyzed together, showed greater educational inequalities related to homicides in years of economic recession when compared to those of economic growth. On the one hand, the indiscriminate use of force by the State against criminal groups seems to increase social inequality in homicide mortality. On the other hand, criminal fragmentation and economic crisis can exacerbate these inequalities by increasing territorial disputes between criminal groups.

Se sabe poco sobre cómo las fluctuaciones económicas afectan las desigualdades educativas en homicidios en países latinoamericanos. Los objetivos de este estudio fueron (a) analizar las variaciones temporales de las desigualdades relativas educacionales de la mortalidad por homicidio, y (b) comparar estas desigualdades entre años de crecimiento económico y años de recesión en ciudades del sur sudamericano durante el período 2000-2019. Se utilizaron datos de siete áreas urbanas, en tres países del Cono Sur Sudamericano: Mendoza y Rosario (Argentina); Belo Horizonte, Curitiba, Rio de Janeiro y São Paulo (Brasil); y Santiago (Chile). Se estimaron modelos de Poisson, utilizando como variables explicativas la edad, sexo, año, ciudad de residencia, año de expansión o recesión económica y nivel educativo. Encontramos diferencias marcadas en la evolución temporal de las tasas de homicidio entre las siete ciudades, aunque siempre las poblaciones de nivel educativo bajo fueron las más vulnerables. Las cuatro ciudades de Brasil, analizadas en conjunto, tuvieron desigualdades educativas relativas de homicidios mayores en años de recesión económica, con respecto a años de crecimiento económico. Por un lado, el uso de la fuerza indiscriminado por parte del Estado enfocado hacia grupos criminales parece haber llevado a una creciente desigualdad social de la mortalidad por homicidio. Por el otro, en un contexto de fragmentación criminal y crisis económica se podrían agravar estas desigualdades a través de mayores disputas territoriales entre grupos criminales.

São escassas as informações sobre como as flutuações econômicas afetam as desigualdades educacionais em homicídios na América Latina. Os objetivos deste estudo foram: (a) analisar as variações temporais das desigualdades educacionais relacionadas à mortalidade por homicídio, e (b) comparar essas desigualdades entre os anos de crescimento econômico e os anos de recessão nas cidades do sul da América do Sul no período de 2000 a 2019. Foram utilizados dados de sete áreas urbanas, em três países do Cone Sul da América do Sul: Mendoza e Rosário (Argentina); Belo Horizonte, Curitiba, Rio de Janeiro e São Paulo (Brasil); e Santiago (Chile). Os modelos de Poisson foram estimados utilizando como variáveis explicativas a idade, sexo, ano, cidade de residência, ano de expansão ou recessão econômica e nível de escolaridade. Os resultados mostraram diferenças significativas na evolução temporal das taxas de homicídio entre as sete cidades, apesar de que as populações com baixo nível de escolaridade sempre foram as mais vulneráveis. As quatro cidades brasileiras, analisadas em conjunto, apresentaram maiores desigualdades educacionais relacionadas a homicídios em anos de recessão econômica em relação aos anos de crescimento econômico. Por um lado, o uso indiscriminado da força pelo Estado contra grupos criminosos parece ter levado ao aumento da desigualdade social na mortalidade por homicídio. Por outro lado, em um contexto de fragmentação criminal e crise econômica, essas desigualdades podem ser exacerbadas pelo aumento das disputas territoriais entre grupos criminosos.

Cranial trauma in handgun executions: Circumferential delamination defect and its relationship with contact/close-range shooting.

Skeletal evidence usually constitutes the only source of information to interpret lesion patterns that help to clarify the circumstances surrounding death. The examination and interpretation of bone trauma are essential to the application and utility of anthropology as a forensic science. When discussing the effect of gunshot wounds in bone, it becomes imperative to differentiate between short and long-distance injuries based on clear, distinct, and observable signs. To contribute to the debate, our focus is directed toward the external analysis of the so-called circumferential delamination defect (CDD) as an observable proxy for close-range shooting (≤30 cm) and contact gunshot wounds in the skull. In the context of known extrajudicial killings, in which the perpetrators used short 9 × 19 FMJ ammunition in a close-range shooting, instances of CDD have been documented. Empirical evidence reinforcing the causal relationship between CDD and close-range shootings is presented. Elements' characteristics of firearm residues were also found in remains buried for up to 30 years. Primarily, this work shows that the concentrations of gunshot residues (Pb, Ba, and Sb) resemble those observed in fresh corpses with the same gunshot wound (GSW). Moreover, the correlation observed between CDD and gunshot residues, where the likelihood of CDD increases the closer to the head and the more perpendicular the shot angle is, reinforces CDD as a pivotal discriminatory factor in the skeletal evidence of short-range or contact shot. This research contributes to the field of forensic anthropology by providing fundamental insights into the etiology of CDD and its practical application.

States' Abortion Laws Associated With Intimate Partner Violence-Related Homicide Of Women And Girls In The US, 2014-20.

Women who are pregnant or recently gave birth are significantly more likely to be killed by an intimate partner than nonpregnant, nonpostpartum women of reproductive age, implicating the risk of fatal violence conferred by pregnancy itself. The rapidly increasing passage of state legislation has restricted or banned access to abortion care across the US. We used the most recent and only source of population-based data to examine the association between state laws that restrict access to abortion and trends in intimate partner violence-related homicide among women and girls ages 10-44 during the period 2014-20. Using robust difference-in-differences ecologic modeling, we found that enforcement of each additional Targeted Regulation of Abortion Providers (TRAP) law was associated with a 3.4 percent increase in the rate of intimate partner violence-related homicide in this population. We estimated that 24.3 intimate partner violence-related homicides of women and girls ages 10-44 were associated with TRAP laws implemented in the states and years included in this analysis. Assessment of policies that restrict access to abortion should consider their potential harm to reproductive-age women through the risk for violent death.

"There's room to do more": a mixed-methods study of the Temporary Assistance for Needy Families (TANF) diversion program and intimate partner violence in Georgia.

Introduction: Intimate partner violence (IPV) is a risk factor for homicides and suicides. As poverty is both a predictor and a consequence of IPV, interventions that alleviate poverty-related stressors could mitigate IPV-related harms. Temporary Assistance for Needy Families (TANF), a monthly cash assistance program, is one such potential intervention. In the state of Georgia, the TANF diversion program, which provides a non-recurrent lump-sum payment to deter individuals from monthly TANF benefits, is an understudied component of TANF that may influence the effectiveness of state TANF programs in supporting IPV survivors. Aim: This study quantifies and qualifies the role of Georgia's TANF diversion program in shaping IPV-related mortality. Methods: This study relies on a mixed-methods sequential explanatory design. Using data from the Georgia Violent Death Reporting System (GA-VDRS), an interrupted time series analysis was conducted to estimate the effect of TANF diversion on IPV-related homicides and suicides. Semi-structured interviews were then administered with TANF policy experts and advocates, welfare caseworkers, and benefit recipients (n = 20) to contextualize the quantitative findings. Results: The interrupted time series analysis revealed three fewer IPV-related deaths per month after implementing TANF diversion, compared to pre-diversion forecasts (coefficient = -3.003, 95%CI [-5.474, -0.532]). However, the qualitative interviews illustrated three themes regarding TANF diversion: (1) it is a "band-aid" solution to the access barriers associated with TANF, (2) it provides short-term relief to recipients making hard choices, and (3) its limitations reveal avenues for policy change. Discussion: While diversion has the potential to reduce deaths from IPV, it may be an insufficient means of mitigating the poverty-related contributors to IPV harms. Its limitations unveil the need for improved programs to better support IPV survivors.

In Vitro Fertilization, State Wrongful Death Statutes and State Fetal Homicide Statutes: The Reaction to LePage v. Center for Reproductive Medicine.

The Alabama Supreme Court recently held, in LePage v. Center for Reproductive Medicine, that the parents of human embryos that were negligently destroyed at a fertility clinic could bring an action for damages under the State's wrongful death statute. Although the Alabama legislature promptly enacted a law essentially overturning the state supreme court's decision, concerns have been raised that the court's decision might influence courts in other States to interpret their wrongful death statutes, or possibly even their fetal homicide statutes, to apply in similar circumstances, thereby threatening the availability of in vitro fertilization (IVF) technology. This article addresses those concerns.With respect to wrongful death statutes, only fourteen States (excluding Alabama) have interpreted their statutes to apply to unborn children without regard to their stage of gestation or development. The majority of States impose a gestational requirement (typically, viability) which would preclude their application to the destruction of human embryos. Even with respect to the minority of States that impose no limitation on the cause of action, those statutes, either by their express language or by fair interpretation, would not apply to unimplanted human embryos.With respect to the fetal homicide statutes in thirty-one States that do not have any gestational or developmental limitation, the statutes in twenty-six of those States apply only to acts causing the death of an unborn child in utero. As to the statutes in the other five States, the structure of the statute, considered in light of the applicable case law, strongly suggests that there would be no liability for causing the death of an unborn child before implantation. In sum, the Alabama Supreme Court's decision in LePage is not likely to be followed as a precedent in interpreting either the wrongful death statutes or the fetal homicide statutes of any other State.

Characterization of Homicides in Mexico: Analysis of 2015-2022.

BACKGROUND: In Mexico, homicides are the leading cause of death among men aged 15 to 44 years; however, despite their increase in recent decades, the study of this issue is insufficient, given its magnitude and impact. Therefore, this study aimed to characterize the spatial and temporal patterns and associated factors of homicides in Mexico from 2015 to 2022. METHODS: An analytical cross-sectional study was conducted, analyzing death records from the National Institute of Statistics and Geography's general mortality databases. Simple frequencies and incidence rates per 100,000 inhabitants by sex, year, and state of the Mexican Republic were calculated. Mortality was evaluated by age groups and geographic areas, and bivariate logistic regression models with sociodemographic variables were performed. RESULTS: Records of 229,182 homicides in Mexico were analyzed, with a median age of 33 years, interquartile range 18. A total of 203,898 (88.96%) were men and 25,284 (11.04%) were women. The majority of deaths occurred in public places and were caused by firearms; women had a higher percentage of homicides at home. States with high incidence rates for both sexes were Chihuahua, Zacatecas, Michoacán, Colima, and Estado de México. The total years of life lost were 9.19 million years. The national incidence of homicides in men showed an upward trend from 2015 to 2019; however, in the case of women, this incidence increased in various age groups during the study period. Occupation, education, marital status, and place of occurrence had significant associations in the logistic regression models. CONCLUSIONS: This study provides a spatial-temporal characterization of homicides in Mexico between 2015 and 2022, highlighting the high incidence in men and the upward trend in certain age groups among women. These findings underscore the need for preventive measures and public policies to address this issue in a multisectoral manner.

Police killings of unarmed Black persons and suicides among Black youth in the US: A national time-series analysis.

INTRODUCTION: Suicide deaths among Black youth in the US have increased rapidly over the past decade. Direct or vicarious racial trauma experienced through exposure to police brutality may underlie these concerning trends. METHODS: We obtained nationally aggregated monthly counts of suicides for non-Hispanic Black and White youth (age ≤ 24 years) and adults (age > 24 years) from the National Mortality Vital Statistics restricted-use data files provided by the Centers for Disease Control and Prevention, from 2013 to 2019. Monthly counts of Black youth suicides constituted our main outcome. We defined our exposure as the monthly counts of police killings of unarmed Black persons over 84 months (2013 to 2019), retrieved from the Mapping Police Violence database. We used ARIMA (AutoRegressive Integrated Moving Average) time-series analyses to examine whether Black youth suicides increased within 0 to 3 months following police killings of unarmed Black persons, controlling for autocorrelation and corresponding series of White youth suicides. RESULTS: Suicides among Black youth increase by ∼1 count three months following an increase in police killings of unarmed Black persons (exposure lag 0 coefficient = 0.16, p > 0.05; exposure lag 1 coefficient = -0.70, p > 0.05; exposure lag 2 coefficient = -0.54, p > 0.05; exposure lag 3 coefficient = 0.95, p < 0.05). The observed increase in suicides concentrates among Black male youth (exposure lag 3 coefficient = 0.88, p < 0.05).

Risk for Suicide and Homicide Peaks at Night: Findings From the National Violent Death Reporting System, 35 States, 2003-2017.

Objective: The Mind after Midnight hypothesis proposes that nocturnal wakefulness increases the risk for dysregulated behaviors. Prior studies highlight a greater risk for suicide at night after adjusting for population wakefulness. How this risk varies hour to hour, differs across subgroups, or applies to other behaviors is unknown.Methods: Data on 78,647 suicides and 50,526 homicides from the National Violent Death Reporting System were combined with population wakefulness data for 2003-2017 from the American Time Use Survey. Hourly incident risk ratios (IRRs) were estimated after adjusting for population wakefulness. Two-way analysis of variances identified significant time-by-subgroup interactions that were quantified in post hoc analyses.Results: Suicide counts peaked at 12:00 PM, while homicide counts peaked at 10:00- 11:00 PM. Adjusting for demographics and population wakefulness revealed a 5-fold greater risk for suicide at 3:00 AM (aIRR: 5.20 [4.74-5.70]) and an 8-fold greater risk for homicide at 2:00 AM (aIRR: 8.04 [6.35-10.2]). Hourly risk for suicide varied by age, ethnicity, blood alcohol level, and current partner conflict. Hourly risk for homicide varied by sex and blood alcohol level.Conclusions: Risk for suicide and homicide is greater at night than expected based on the number of people awake at that time. Nighttime risk was greater among young adults and those intoxicated with alcohol, but not among those with a history of suicidal ideation or attempts. Further research should evaluate mechanisms of risk and confirm these findings at an individual level.

To investigate the pattern of neck injuries and the role of toxicology in cases of hanging and manual/homicidal ligature strangulation in Ireland between 2016 - 2020: A retrospective review and analysis.

The pattern of neck injuries sustained in fatal cases of external compression to the neck is recorded during Post Mortem Examinations (PME), to assist in the interpretation of the circumstances that led to death. In this study, the PMEs performed for 298 cases of hanging and strangulation occurring between 2016 and 2020 in Ireland were retrospectively reviewed for the purpose of recording and collating the external and internal neck injuries observed during each PME, as well as the toxicology results for each decedent. Statistical analysis was performed to investigate potential novel associations between anthropometric variables pertaining to the decedents and the PME findings in cases of hanging and strangulation, serving to add further data to the existing body of research in this area and to assist in the resolution of future cases of hanging or strangulation where there are conflicting findings. In completing statistical analysis, it was found that there was no discernible association between the occurrences of cartilaginous neck fractures (CNFs) with increasing ligature width. Positive associations between increasing weight and BMI of the decedents were identified, and a significantly positive association between the increasing height of the decedent and the incidence of CNFs were identified. Analysis of the toxicology demonstrated that antipsychotics were implicated most frequently in cases of incomplete and complete hanging associated with CNFs and that opioids were implicated most frequently in cases of manual and ligature strangulation associated with CNFs. OBJECTIVE: To record the pattern of neck injuries sustained in retrospective cases of hanging and manual/ligature strangulation and to collate these findings so as to provide scientific evidence to support the interpretation of the findings in future cases of suicidal hanging and homicidal manual/ligature strangulation for the purpose of medicolegal investigation. To analyse the associations between the occurrence of neck fractures and anthropometric variables pertaining to the victims in cases of complete hanging. STUDY DESIGN: The reports of 298 Post Mortem Examinations (PMEs) performed for cases of hanging and manual/homicidal ligature strangulation between 2016 and 2020 in Ireland were retrospectively reviewed. Pseudoanonymised data sets were recorded for each report, which included the following parameters: neck injuries (soft tissue and cartilaginous), weight, height, BMI and ligature width, toxicology, noose position, ligature material, tongue protrusion, sex and age. Permission for the use of this data was sought from the pathologists and coroners involved in these cases. The data was analysed according to descriptive statistical methods and logistic regression analysis. RESULTS: Logistic regression analysis was undertaken to examine the associations between unit increases in ligature width and increases in a set of physical characteristics of the decedents (weight, BMI and height) with the occurrence of CNFs. Increasing ligature width was not found to increase the likelihood of a CNF occurring, where the Odds Ratio (OR) for this event occurring was 0.9596. Unit increases in body weight and BMI were found to increase the likelihood of the occurrence of a CNF with ORs of 1.0166 and 1.0607 respectively. Increasing height of the decedent yielded an OR = 4.64, demonstrating that CNFs are significantly more likely to occur with increasing height (CI 95 %: 0.2915, 73.9559). CONCLUSIONS: According to the statistical analysis performed for this study, increasing weight, height and BMI are parameters of the decedents which increase the likelihood of the occurrence of CNFs in cases of complete hanging.

3D scanning a crime scene to enhance juror understanding of Bloodstain Pattern Analysis evidence.

There are numerous crime scene investigation applications of 3D scanning that have been previously documented. This paper documents the application of a 3D point cloud in the presentation of Bloodstain Pattern Analysis evidence to mock jurors. 150 mock jurors viewed a presentation of Bloodstain Pattern Analysis evidence from a murder trial in the UK. After viewing the evidence, the participants were tested on their knowledge of the evidence and repeated the test again 2 weeks later; to simulate criminal trial conditions; whereby there is a time lapse between the initial viewing of evidential material and deliberation. This paper found that the mock jurors who additionally viewed a 3D flythrough of a point cloud of the crime scene, better retained knowledge of the evidence over time, reported a greater ability to visualise the crime scene and had higher levels of interest in the evidence. Crucially, the 3D flythrough group did not report different levels of confidence in the accuracy of their memories of the evidence, nor different levels of emotional arousal to the group that viewed the evidence without the 3D presentation. Together, these findings suggest that 3D scanning of crime scenes, and the resultant point cloud's presentation to jurors, could add further value to the justice system when spatial information, such as Bloodstain Pattern Analysis evidence, is presented.

Evaluating Firearm Violence After New Jersey's Cash Bail Reform.

Importance: Reducing the pretrial detention population has been a cornerstone of movements to end mass incarceration. Across many US cities, there are ongoing public debates on policies that would end pretrial detention due to the inability to afford bail, with some raising concerns that doing so would increase community violence. Objective: To evaluate changes in firearm violence after New Jersey's 2017 bail reform policy that eliminated financial barriers to avoiding pretrial detention. Design, Setting, and Participants: This case-control study used synthetic control methods to examine changes in firearm mortality and combined fatal and nonfatal shootings in New Jersey (2014-2019). New Jersey was chosen because it was one of the first states to systematically implement cash bail reform. Outcomes in New Jersey were compared with a weighted combination of 36 states that did not implement any kind of reform to pretrial detention during the study period. Data were analyzed from April 2023 to March 2024. Exposure: Implementation of New Jersey's cash bail reform law in 2017. Main Outcomes and Measures: Quarterly rates of fatal and nonfatal firearm assault injuries and firearm self-harm injuries per 100 000 people. Results: Although New Jersey's pretrial detention population dramatically decreased under bail reform, the study did not find evidence of increases in overall firearm mortality (average treatment effect on the treated, -0.26 deaths per 100 000) or gun violence (average treatment effect on the treated, -0.24 deaths per 100 000), or within racialized groups during the postpolicy period. Conclusions and Relevance: Incarceration and gun violence are major public health problems impacting racially and economically marginalized groups. Cash bail reform may be an important tool for reducing pretrial detention and advancing health equity without exacerbating community violence.

Firearm Homicide Demographics Before and After the COVID-19 Pandemic.

This cross-sectional study evaluates changes in firearm homicide demographics before and after the COVID-19 pandemic.

Racial and Ethnic Disparities in All-Cause and Cause-Specific Mortality Among US Youth.

Importance: Mortality rates in US youth have increased in recent years. An understanding of the role of racial and ethnic disparities in these increases is lacking. Objective: To compare all-cause and cause-specific mortality trends and rates among youth with Hispanic ethnicity and non-Hispanic American Indian or Alaska Native, Asian or Pacific Islander, Black, and White race. Design, Setting, and Participants: This cross-sectional study conducted temporal analysis (1999-2020) and comparison of aggregate mortality rates (2016-2020) for youth aged 1 to 19 years using US Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research database. Data were analyzed from June 30, 2023, to January 17, 2024. Main Outcomes and Measures: Pooled, all-cause, and cause-specific mortality rates per 100 000 youth (hereinafter, per 100 000) for leading underlying causes of death were compared. Injuries were classified by mechanism and intent. Results: Between 1999 and 2020, there were 491 680 deaths among US youth, including 8894 (1.8%) American Indian or Alaska Native, 14 507 (3.0%) Asian or Pacific Islander, 110 154 (22.4%) Black, 89 251 (18.2%) Hispanic, and 267 452 (54.4%) White youth. Between 2016 and 2020, pooled all-cause mortality rates were 48.79 per 100 000 (95% CI, 46.58-51.00) in American Indian or Alaska Native youth, 15.25 per 100 000 (95% CI, 14.75-15.76) in Asian or Pacific Islander youth, 42.33 per 100 000 (95% CI, 41.81-42.86) in Black youth, 21.48 per 100 000 (95% CI, 21.19-21.77) in Hispanic youth, and 24.07 per 100 000 (95% CI, 23.86-24.28) in White youth. All-cause mortality ratios compared with White youth were 2.03 (95% CI, 1.93-2.12) among American Indian or Alaska Native youth, 0.63 (95% CI, 0.61-0.66) among Asian or Pacific Islander youth, 1.76 (95% CI, 1.73-1.79) among Black youth, and 0.89 (95% CI, 0.88-0.91) among Hispanic youth. From 2016 to 2020, the homicide rate in Black youth was 12.81 (95% CI, 12.52-13.10) per 100 000, which was 10.20 (95% CI, 9.75-10.66) times that of White youth. The suicide rate for American Indian or Alaska Native youth was 11.37 (95% CI, 10.30-12.43) per 100 000, which was 2.60 (95% CI, 2.35-2.86) times that of White youth. The firearm mortality rate for Black youth was 12.88 (95% CI, 12.59-13.17) per 100 000, which was 4.14 (95% CI, 4.00-4.28) times that of White youth. American Indian or Alaska Native youth had a firearm mortality rate of 6.67 (95% CI, 5.85-7.49) per 100 000, which was 2.14 (95% CI, 1.88- 2.43) times that of White youth. Black youth had an asthma mortality rate of 1.10 (95% CI, 1.01-1.18) per 100 000, which was 7.80 (95% CI, 6.78-8.99) times that of White youth. Conclusions and Relevance: In this study, racial and ethnic disparities were observed for almost all leading causes of injury and disease that were associated with recent increases in youth mortality rates. Addressing the increasing disparities affecting American Indian or Alaska Native and Black youth will require efforts to prevent homicide and suicide, especially those events involving firearms.

Physician homicide: Reports in the National Violent Death Reporting System (2003-2018).

OBJECTIVE: To explore the occurrence, demographics, and circumstances of homicides of physicians. METHOD: Authors interrogated the National Violent Death Reporting System (NVDRS), the Centers for Disease Control and Prevention's surveillance system tracking violent deaths between 2003 and 2018 which integrates data from law enforcement and coroner/medical examiner reports. Authors identified cases of homicide decedents whose profession was physician, surgeon, or psychiatrist. Data collected included decedents' demographics as well as circumstances of death. RESULTS: Data were provided by 7-41 states as participating states increased over time. Fifty-six homicides were reported, most were male (73.2%) and white (76.8%). Most (67.9%) identified assailants reportedly knew decedents: 23.2% were perpetrated by partners/ex-partners; 10.7% by patients/patients' family members. Deaths were mainly due to gunshot wounds (44.6%), stabbing (16.1%), and blunt force trauma (16.1%). More (58.9%) homicides occurred at victims' homes than work (16.1%). CONCLUSIONS: Physician homicides are relatively rare and occur at lower rates than in the general population. Physicians were more frequently killed by partners or ex-partners than by patients. Most homicides occurred away from the workplace. Broader efforts are needed to promote interventions throughout America's violent society to reduce domestic/partner violence and gun violence.

Race, disadvantage, and violence: A spatial exploration of macrolevel covariates of police-involved homicides within and between US counties.

Efforts to explore the macrolevel determinants of police-involved homicides have expanded in recent years due in part to increased scrutiny and media attention to such events, and increased data availability of these events through crowdsourced databases. However, little empirical research has examined the spatial determinants of such events. The present study extends the extant macrolevel research on police-involved homicides by employing an underutilized spatial econometric model, the spatial Durbin model (SDM), to assess the direct and indirect county effects of racial threat, economic threat, social disorganization, and community violence on police killings within and between US counties from 2013 through 2020. Results indicate a direct inverse relationship between racial threat and police-involved homicides, no support for economic threat, and a direct positive association with two measures of social disorganization. Additionally, we find firearm availability exhibits significant direct and indirect spatial dependence on focal county police-involved homicides, reflecting spatial spillover processes. In essence, as firearm availability in neighboring counties increases, police-involved homicides within a focal county increase. The implications of these findings for racial threat, economic threat, social disorganization, and community violence are discussed.

Who is killing South African men? A retrospective descriptive study of forensic and police investigations into male homicide.

Not much is known about the perpetrators of male homicide in South Africa, which has rates seven times the global average. For the country's first ever male homicide study we describe the epidemiology of perpetrators, their relationship with victims and victim profiles of men killed by male versus female perpetrators. We conducted a retrospective descriptive study of routine data collected through forensic and police investigations, calculating victim and perpetrator homicide rates by age, sex, race, external cause, employment status and setting, stratified by victim-perpetrator relationships. For perpetrators, we reported suspected drug and alcohol use, prior convictions, gang-involvement and homicide by multiple perpetrators. Perpetrators were acquaintances in 63% of 5594 cases in which a main perpetrator was identified. Sharp objects followed by guns were the main external causes of death. The highest rates were recorded in urban informal areas among unemployed men across all victim-perpetrator relationship types. Recreational settings including bars featured prominently. Homicides clustered around festive periods and weekends, both of which are associated with heavy episodic drinking. Perpetrator alcohol use was reported in 41% of homicides by family members and 50% by acquaintances. Other drug use was less common (9% overall). Of 379 men killed by female perpetrators, 60% were killed by intimate partners. Perpetrator alcohol use was reported in approximately half of female-on-male murders. Female firearm use was exclusively against intimate partners. No men were killed by male intimate partners. Violence prevention, which in South Africa has mainly focused on women and children, needs to be integrated into an inclusive approach. Profiling victims and perpetrators of male homicide is an important and necessary first step to challenge prevailing masculine social constructs that men are neither vulnerable to, nor the victims of, trauma and to identify groups at risk of victimisation that could benefit from specific interventions and policies.
