The past two decades have seen a sustained rise in multi-defendant homicide prosecutions

This report tracks multi-defendant homicide prosecutions in England and Wales and the concerns they raise around fairness, youth involvement, and racial disproportionality. Drawing on Home Office and CPS data from 2005–2024, it finds that prosecutions involving multiple defendants have become more common, with young people disproportionately represented among those convicted. It also highlights persistent racial disparities and increasingly severe sentencing outcomes for those convicted.

The report situates these findings within wider academic and policy debates on joint enterprise and shared responsibility in serious crime. Authors make the case for government attention and intervention on three key issues: 

• Narrow the scope of the law: Via a workable test for when someone can be held liable for the crimes of another.

• Proportionate sentencing: With a separate sentencing framework for secondary parties.

• Greater transparency and accountability: Requiring prosecutors to state each defendant's individual conduct and intent, and identify possible alternative charging.

 Background: Firearm homicide is a leading cause of death in the United States, with substantial racial disparities documented over time. Black Americans experience disproportionately higher rates of firearm homicide compared to White Americans, reflecting long-standing social, economic, and structural inequities. This study contributes to understanding the magnitude and trends of this disparity. Objective: We investigate the Black-White population-level disparity in firearm homicide rates over 45 years in the United States and estimate the fraction of excess deaths in the Black population attributable to firearm homicides. Methods: We measure racial disparities in firearm homicides as the ratio of ageadjusted rates between Black and White populations. Using annual national firearm homicide and population data from CDC WONDER (1979–2023), disaggregated by race, age, and sex, we calculate age-adjusted Black–White mortality ratios by year and sex, as well as the number of excess Black firearm homicide deaths attributable to these disparities. Results: After a steady period of 1990-2010, the Black-White disparity began increasing and peaked in 2020 when the firearm homicide rate in males was 10.38 times higher in Blacks than Whites. There were 31,202 excess firearm homicides of Black people attributed to the Black-White racial disparity in 2021-2023. Conclusions: Despite significant declines in firearm homicides during the 1990s, the relative racial gap in firearm homicide has persisted and grown, reflecting the unequal burden of violence borne by the Black population during both declines and surges of violence.

Records from the Central Register of Female Prisoners permit a longitudinal analysis of ninety-five women convicted of murder and manslaughter in Victoria between 1860 and 1920. The data show the similarities and differences between the women convicted of these homicide offenses. An examination of the women’s socioeconomic profiles, occupations, ages, migrations, and victims reveals the links between their crimes and their punishment.

Socio-economic status, demographic background and criminal history.

By Lisa Westfelt

This study focuses on aspects that have not yet been examined in Swedish research: the socio-economic status and demographic background of victims and perpetrators at the time homicides are committed, as well as the victims and perpetrators’ criminal histories.

Scope, trends and characteristics.

By Klara Hradilova-Selin

This study is the fourth in a series of Brå’s research reports on homicide in Sweden, based on material from the criminal justice system. The analyses build on audited data from police preliminary investigations and, in cases that have been cleared, judgments obtained from both district courts and appeal courts. The aim has been to outline trends in and characteristics of homicide cases since 1990, with a particular focus on the most recent period for which data have been collected, 2018–2021. Some analyses also include data from Brå’s statistics on confirmed cases of lethal violence for 2022 and 2023. 

Report 2024:6

By Arthur MacDonald.

The narrative in Volume 1 asks many pointed questions: What does it mean to be “abnormal”? Who decides? And how have these judgments shaped modern science, education, and criminal justice?

First published in 1893, Arthur MacDonald’s Abnormal Man is one of the earliest American attempts to systematically study human difference through the emerging tools of psychology, anthropology, and criminology. Drawing on international research—from European criminal anthropology to American child-study movements—MacDonald sought to classify the physical, mental, and moral traits considered “aberrant” in his era. His work reflects the hopes and anxieties of a society confronting rapid industrialization, immigration, social change, and new scientific approaches to crime and mental health.

To the modern reader, Abnormal Man reveals both the ambition and the pitfalls of nineteenth-century science. Its pages contain pioneering observations about child development, deviance, and social responsibility, alongside early theories—now discredited—about heredity, physiognomy, and race. What emerges is a vivid and sometimes unsettling portrait of a culture striving to understand human variation without the benefit of modern psychology or ethical safeguards.

The Read-Me.org edition Volume 1 presents Abnormal Man as both a historical artifact and a gateway to critical reflection. It illustrates how scientific thought evolves, how cultural bias can shape research, and how early debates about abnormality laid the groundwork for contemporary approaches to mental health, special education, criminology, and social policy. To make such work, much of it controversial then as it is today, minimally believable, requires extensive documentation. The voluminous Bibliography of Abnormal Man reproduced here in Volume 2, contains all that Macdnald referred to within his detailed exposition. To some, his arguments may seem unsupported, or lacking in evidence. But he left no stone untuned as this amazing bibliographical documentation of all relative contemporary research

A foundational text at the crossroads of science and society, Abnormal Man invites readers to explore the origins of modern debates about deviance, diversity, and the boundaries of the “normal.”

BY Richard Grelling.. Translated By Alexander Gray. Introduction by Colin Heston.

Richard Grelling’s The Crime (Das Verbrechen), translated into English by Alexander Gray and published in London and New York between 1917 and 1919, is conceived as both a moral successor and completion to his earlier pacifist landmark, J’Accuse!, written between August 1915 and November 1916. In creating this extended work, Grelling sought to underscore the causes of World War I and dissect the self-justifying rhetoric that sustained the conflict long after its outbreak. Volumes I and II lay foundational groundwork, tracing the immediate antecedents of the war: imperialist tendencies within Germany and, on the part of the opposing Entente powers, ostensibly defensive motives followed by trait protectionism.

Never before in the annals of humankind has a crime of such sweeping magnitude been committed—and seldom has its perpetration been met with denial so unashamed. Within the very citadels of reason and culture, a proud civilization unleashed catastrophe under the guise of necessity—only to scramble afterward in self-exculpation. It is in this spirit of moral defiance—standing firm against voices of dissent, even from one’s own kin—that The Crime is offered to you. In the trilogy’s third volume, Grelling moves beyond the origins of war into the heart of wartime rationalization, exposing the “war-aims” that enabled aggression to persist under the cloak of purpose. May this work cast a clear light upon the structures of self-deception that allowed the world’s descent, and may it stir an unyielding clarity in us to recognize—and reject—such patterns again.

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.
