A special type of homicide-suicide: A retrospective study of the characteristics of extended suicide.

Extended suicide, a specific type of homicide-suicide event, has severe social consequences yet remains lacking systematic research. This retrospective study investigated 51 cases of extended suicide involving mental disorders in central China with aim of better understanding risk factors for such events and guiding prevention strategies. Over an 8-year period from 2015 to 2022, cases were collected from forensic institutions, and demographic characteristics, case details, and psychiatric data were recorded. The 51 incidents involved 51 perpetrators and 79 victims, with more female perpetrators (58.8%) and more female victims (54.4%). The average age of the perpetrators was 36.1, and most were married (88.2%). Almost all of the victims were family members of the perpetrator, like the most numerous children (64.6%), followed by spouses (24.1%). The most common homicide mode of death was mechanical asphyxia (38.0%), followed by sharp devices (36.7%) and drug poisoning (16.5%). Depressive disorders (76.5%) were the most common diagnosis of mental disorder for perpetrators. The study analyzed the unique characteristics of extended suicide to enrich such data. These findings help strengthen the screening and identification of potential perpetrators and victims to prevent such cases from occurring.

Population-Level Alcohol Consumption and Homicide Rates in Latin America: A Fixed Effects Panel Analysis, 1961-2019.

Latin America and the Caribbean (LAC) possesses 8 per cent of the global population but approximately one-third of global homicides. The region also exhibits high per capita alcohol consumption, risky drinking patterns and a heterogeneous mix of beverage preferences. Despite this, LAC violence receives limited attention in the English-language literature and there are no studies of the population-level alcohol-homicide association in the region. We examined the effects on total, male and female homicide rates of total and beverage-specific alcohol consumption (22 nations, 1961-2019) and of risky drinking patterns (20 nations, 2005 and 2010). We collected homicide and alcohol data from the World Health Organization. Panel fixed effects models showed (1) per capita total and wine consumption were positively associated with total, male and female homicide rates, though effects were much stronger for males, (2) per capita beer consumption was positively associated with total and male homicide rates, (3) per capita spirits consumption was not associated with homicide rates, and (4) nations with riskier drinking patterns had higher total, male and female homicide rates than those with less risky drinking patterns.

Homicide numbers, rates, and victims' characteristics in the Tri-City metropolitan area, Poland, between 2010 and 2019. / Liczby i wskazniki zabójstw oraz charakterystyka ofiar na terenie aglomeracji Trójmiasta w latach 2010-2019.

Despite a clear global downward trend, homicides still account for a relatively high proportion of all violent deaths, making them a serious problem both in Poland and worldwide. The discrepancy in available data prompted the authors of the study to analyse the numbers and rates of homicides and the characteristics of the homicide victims in the Tri-City area of northern Poland. The study was based on data from autopsy reports, supplemented by information from prosecutor's files on all homicides in the Tri-City area between 2010 and 2019. A total of 107 homicides were statistically analysed for age, sex, blood alcohol concentration at the time of death, time and place of death. The annual homicide rate was 1.24 per 100,000 inhabitants, with a clear downward trend over the period analysed. The average age of victims was about 48 years, and the majority of victims were male (70.1%). 92.5% of homicides were committed in the Tri-City, with a clear predominance of Gdansk (49.5%) over other, mostly rural, areas of the analysed agglomeration. The majority of victims (57.8%) whose blood alcohol concentration was measured were intoxicated, with a clear predominance of males in this group (70.9%). Victim characteristics and the homicide rates obtained from the analysed material were similar to other countries in Central and Eastern Europe, which may be related to historical, cultural, and demographic similarities. The study highlights the significant impact of alcohol abuse on the risk of homicide.

Trophy, souvenir, or simple theft? Taking items from the victim in sexual homicide.

Although most people have heard the terms 'souvenirs', 'trophies', and 'mementos', discussed in books and movies on the true crimes of sexual murderers, limited research has delved into the phenomenon of theft in sexual homicide (SH). Using a sample of 762 SH cases coming from the Sexual Homicide International Database, the current study examines the crime-commission process of the pre-crime, crime, and post-crime phases of sexual homicide offenders (SHOs) who engaged in theft during a SH. Additionally, this study seeks to determine if a specific type of SHO engages in this behaviour over others. Results from the sequential logistic regression indicate that victims who are 16 years or older, were strangers to the SHO, and were sex workers were more likely to be victims of theft. Additionally, results indicate that the presence of sadism made it more likely the SHO would engage in theft from the victim and/or crime scene. Findings suggest there is a group of SHOs who engage in theft not for monetary purposes but due to the paraphilia of the offender. These findings can inform the police investigation of these crimes.

Trends in workplace homicides in the U.S., 1994-2021: An end to years of decline.

Workplace and non-workplace homicides in the United States (U.S.) have declined for over 30 years until recently. This study was conducted to address the change in trends for both workplace and non-workplace homicides and to evaluate the homogeneity of the change in workplace homicides by specified categories. Joinpoint and autoregressive models were used to assess trends of U.S. workplace and non-workplace homicides utilizing surveillance data collected by the Bureau of Labor Statistics and the Federal Bureau of Investigation from 1994 through 2021. Both workplace and non-workplace homicides decreased significantly from 1994 through 2014. Workplace homicides showed no significant trend from 2014 through 2021 (p = 0.79), while non-workplace homicides showed a significant average annual increase of 4.1% from 2014 through 2020 (p = 0.0013). The large decreases in the trend of workplace homicides occurring during a criminal act, such as robbery, leveled off and started to increase by the end of the study period (p < 0.0001). Declines in workplace homicides due to shootings also leveled off and started to increase by the end of the study period (p < 0.0001). U.S. workplace and non-workplace homicide rates declined from the 1990s until around 2014. Trends in workplace homicides varied by the types of the homicide committed and by the type of employee that was the victim. Criminal-intent-related events, such as robbery, appear to be the largest contributor to changes in workplace homicides. Researchers and industry leaders could develop and evaluate interventions that further address criminal-intent-related workplace homicides.

How to get away with (sexual) murder? Unraveling cold cases in sexual homicide using a hybrid modeling probabilistic approach.

This study examines Sexual Homicide (SH) cases, analyzing the transition to cold cases through a non-discretionary lens. Utilizing the SH International Database, it explores the interplay between offender behavior, victim characteristics, and crime context. Advanced methodologies, including sequential logistic regression and Artificial Neural Networks, identify key predictors of case resolution. Results highlight the critical influence of victim intoxication, high-risk activities, and the location of the victim's body on case solvability. The study also reveals the significant role of offender forensic awareness and the complexity of crime scenes in hindering case resolution. These findings underline the multifaceted nature of SH cases, emphasizing the importance of understanding the nuanced interplay between victim, offender, and contextual factors in solving these challenging cases.

Familicide in Canada, 2010 to 2019.

Familicide is rare; however, the high victim counts in each incident and context surrounding these killings underscore the need for further research. The purpose of this study is to gain a better understanding of the circumstances surrounding familicide in Canada. Using univariate statistics, this study analyzed 26 incidents of familicide that occurred in Canada between 2010 and 2019. The results show that familicide is a gendered crime involving primarily male accused who often target female victims, have a history of domestic violence, and commit the killings using firearms. This research highlights the importance of developing risk assessment, risk management, and safety planning strategies to address warning signs and prevent future familicides.

Mental Health of Homicidally Bereaved Individuals: A Systematic Review of Post-Homicide Factors.

Experiencing the homicide of a loved one has a substantial impact on the mental health of family members and friends who must survive their loved one's tragic death. This systematic review aims to synthesize the current findings on post-homicide factors and identify the factors most frequently related to the mental health of homicidally bereaved individuals (HBI). Four databases were searched (PsycINFO, SCOPUS, Sociological Abstract, PubMed). The selection of studies was based on a peer review process conducted by two independent researchers to ensure interrater reliability. The articles were screened to ensure the presence of homicidally bereaved adults, resulting in a total of 35 eligible papers to be considered in the current review. Factors were organized into categories, with the criminal justice system-related factors (n = 18), social factors (n = 17), and coping factors (n = 13) being the most prevalent. This review identifies clinical avenues for preventing distress and fostering the well-being of HBI.

Community exposure to gun homicide and adolescents' educational aspirations.

INTRODUCTION: Witnessing violence and violent victimization have detrimental effects on adolescents' emotional functioning and ability to envision and plan for their futures. However, research is limited on the impact of violence that occurs in adolescents' communities-whether or not it was witnessed or experienced firsthand. This paper investigated the associations between community exposure to gun homicide and adolescents' high school and college graduation aspirations. METHODS: We analyzed data from the Future of Families and Child Wellbeing Study (N = 3031), a cohort study of children born 1998-2000 in 20 large US cities, merged with incident-level data on deadly gun violence from the Gun Violence Archive (2014-2017). Outcomes were reported by adolescents (girls and boys) during wave 6 (2014-2017) of the study, conducted when the children were 15 years of age. We employed ordinary least squares regression, ordered logistic regression, and multilevel stratification to examine the average and heterogeneous impacts of community exposure to gun homicide on adolescents' educational aspirations. RESULTS: Community exposure to gun homicide was associated with reduced high school graduation aspirations, particularly among adolescents with the lowest risk of exposure to gun homicide. Gun homicide exposure was also associated with increased college graduation aspirations; this association was concentrated among adolescents with moderate-high risk of exposure. CONCLUSIONS: Given the importance of education for job opportunities and the better health that accompanies education and occupational attainment, preventing early exposure to gun violence and providing institutional supports to help adolescents facing adversity realize their goals is essential to their long-term health and success.

Firearm-Related Risks and Consequences for Immigrant Women in Abusive Relationships: Barriers to Reporting Threats to Safety and Recommendations for Safety Planning.

Firearms are the leading cause of intimate partner violence-related murders of women in the US. This study aimed to understand differing consequences of partners' firearm possession on abused women and barriers women face in reporting threats to safety due to the partners' possession of a firearm.. Additionally, the study explored participants' perceptions of effective approaches to risk assessments and safety planning with women who are at-risk for being harmed by their partners' possession of a firearm. Qualitative semi-structured interviews with seventeen service providers and 45 immigrant women survivors of intimate partner violence were conducted. Data were analyzed using content analysis procedure. Participants shared that the partners' possession of a firearm can increase risk for firearm-related injury or fatality in situations of escalation of violence. Abused women living with a partner with firearm possession live in constant fear or threat. The presence of a firearm can also be a trigger of unwanted memories of the past and can have legal and other consequences for survivors. Impediments to reporting threats to safety were barriers such as lack of knowledge of firearm-related risks and gender and social norms. The findings can be informative for safety planning with survivors of IPV whose partners own or have access to a firearm. Comprehensive assessment of risks and barriers can be used to develop individualized and tailored safety plans for survivors with a partner who possesses a firearm.

Invisible Wounds: Exploring the Coping Strategies of Black Survivors of Homicide Victims in Canada.

Canada has experienced a steady increase in homicide. Specifically, out of the 10 provinces and 3 territories, Ontario has consistently experienced the highest number of homicides, the majority concentrated within predominantly African, Caribbean, and Black (ACB) communities in the Greater Toronto Area (GTA). Despite this disproportionate reality, there is limited research on the ways in which survivors of homicide victims cope with the murder of their loved ones. This article explores the identification and characterization of coping strategies for ACB survivors of homicide victims residing in five neighbourhoods in the GTA. Participants in this study provided their insights and experiences, highlighting the coping mechanisms employed, the influence of cultural identity, and the challenges they experienced in accessing adequate care following the death of their loved ones. Implications for future research, policy and practice are discussed.

A public health approach to reducing violence within the CARICOM region.

Widespread crime has become a worldwide problem so much so that violence is now ranked fourth globally in its contribution to disability-adjusted life years in the 10 to 24 age group. Homicides, a surrogate marker of violent crime, have shown an upward trend in almost all of the CARICOM countries, and homicide rates over the past 3 years have consistently increased, though the pattern of violence varies by country. This background has informed the need for greater emphasis on the need for a different approach to dealing with crime in the CARICOM region. The CARICOM governments recently hosted a symposium on crime and violence as a public health issue. The public health approach to crime has been used with measurable success in different parts of the world and, more recently in Trinidad, one of the CARICOM countries. The paper outlines the outcomes of the symposium and discusses its implications for the region.

Singular stab wounds to the trunk: Is this suicidal or homicidal?

Differentiating homicidal or suicidal deaths in presence of a singular stab wound to the anterior or lateral trunk is still a challenge in forensic practice. There are numerous criteria in the literature and in current forensic textbooks to distinguish between self-inflicted injuries and homicide. The applicability of these criteria in single stab injuries was examined by elucidating 12 suicides and 33 homicides, each with a single stab injury to the anterior or lateral trunk and were largely confirmed. An instrumentality still stuck in the corpse was always associated with a suicide in the given cohort. In summary, the final evaluation should always be based on an interpretation of the post mortem findings together with the circumstances on site of discovery as well as the results of the police investigation.

Fatal Police Shootings of Victims with Mental Health Crises: A Descriptive Analysis of Data from the 2014-2015 National Violent Death Reporting System.

One in five fatal police shooting victims may have been experiencing a mental health crisis (MHC) at the time of their death [1]. We use data on fatal police shootings from the National Violent Death Reporting System (2014-2015) to (a) identify incidents where the victim is reported to have experienced an MHC at the time of their death, (b) describe the characteristics of these incidents, and (c) compare the characteristics of MHC to fatal police shootings where the victim was not experiencing an MHC at the time of their death. We systematically coded 633 fatal police shootings from 27 states. Descriptive statistics characterized fatal police shootings, including victim characteristics; their mental health status; and contextual information regarding the police encounter (e.g., reason for police call). Overall, 203 of 633 fatal police encounters (32%) involved victims who showed signs of an MHC at the time of their death. Victims were predominantly white, male, and in possession of a firearm. In 3 of 4 cases, the MHC manifested as suicidal ideation despite any relevant documented history among most victims. Among half of suicidal victims, suicidal ideation was expressed verbally and in-person to a family member/intimate partner who subsequently called the police. Dispatch was aware of the MHC in 1 of 4 of total police calls. Overall, fatal police encounters involving those experiencing an MHC accounted for 1 in 3 of our caseloads. Approximately, 3 of 4 mental health calls involved a suicidal person who mainly expressed intent to a loved one in-person.

Reliability in distinguishing murder from accidental event with current forensic criteria in traumatic head injury.

Discovering a body displaying signs of multiple head trauma requires a thorough examination by the forensic pathologist, and a multidisciplinary approach is recommended. However, determining the manner of death is not always possible. We present a case in which the body of a 60-year-old man was discovered lying face down on the floor of his apartment, partially unclothed, surrounded by blood and vomit, and presenting numerous head injuries. The autopsy concluded that the cause of death was a result of post-traumatic brain injury. Nevertheless, applying current criteria made it challenging to ascertain whether the trauma stemmed from an accidental event or an assault.

The Characterization of Violent Deaths Among Asian and Pacific Islander Americans.

INTRODUCTION: Health disparities in the Asian and Pacific Islander Americans (APIAs) community have not been well described, unlike non-Hispanic Black and Hispanic communities. However, there has been a rise in violence against the APIA community. This study explores and characterizes violent death by incident (e.g., homicide, suicide), weapon (e.g., firearm, strangulation), and location types among APIAs as they compare with other racial or ethnic groups. METHODS: We used the National Violent Death Reporting System from 2003 to 2018 to characterize violent deaths among APIA and compared them to all other races. We compared these racial categories in two ways. First, we compared all races as a categorical variable that included six non-Hispanic racial categories including "Other or unspecified" and "two or more races. We then created a binary variable of APIA versus All Other Races for analysis. We explored the incident type of death, substance abuse disorders, mental health history, and gang involvement among other variables. We used Chi-square tests for categorical variables and Mann-Whitney U-tests for continuous variables. RESULTS: Overall, APIAs had a unique pattern of violent death. APIAs were more likely to commit suicide (71.74%-62.21%, P<0.001) and less likely to die of homicide than other races (17.56%-24.31%, P<0.001). In the cases of homicide, APIAs were more likely to have their deaths precipitated by another crime (40.87% versus 27.87%, P < 0.001). APIAs were more than twice as likely to die of strangulation than other races (39.93%-18.06%, P<0.001). Conversely, APIAs were less likely to die by firearm than other races (29.69-51.51, P<0.001). CONCLUSIONS: APIAs have a unique pattern of violence based on analysis of data from the National Violent Death Reporting System. Our data reveal a significant difference in the incident, weapon and location type as compared to Americans of other races, which begs further inquiry into the patterns of change in time and factors that contribute to inter-racial differences in death patterns.

What Are the Experiences of Mental Health Practitioners Involved in a Coroner's Inquest and Other Inquiry Processes after an Unexpected Death of a Patient? A Systematic Review and Thematic Synthesis of the Literature.

Grief after suicide or patient-perpetrated homicide can be complex for those involved in the patient's care. Mental health practitioners with patients who die unexpectedly may be called to assist in the formal investigation processes that follow. The aim of this study was to examine the experience of mental health practitioners called to attend a coroner's inquest or other forms of formal inquiry. A protocol for a systematic review was prospectively registered on PROSPERO (CRD42023400310). A thematic synthesis of existing literature was conducted. We identified six articles for inclusion and constructed three themes from our analysis: Blame and enduring hostility, In the dark, and Limited learning. We found mental health practitioners may construct narratives of self-blame. These can be reinforced by the investigatory processes that follow. Feedback from inquiries is often delivered haphazardly and may not reflect the realities of clinical work. The support given to assist practitioners through inquiry processes varied-both in amount and how helpful it was. The research conducted on this topic is limited. More qualitative research should be conducted to understand the factors that make this experience more or less difficult as well as well as what support is needed for whom.

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.

A controlled method for the identification of forensic traces from clandestine grave fill.

Deceased human remains are often buried as a forensic countermeasure or method of disposal by homicide perpetrators. Owing to this, the excavation of clandestine grave sites is a task that forensic crime scene teams may only encounter a few times a year. Not all crime scene units have specialised teams for this task, and even those that do, may not have specific protocols for the optimal recovery of forensic traces retained within grave fill as procedures such as sieving require optimisation for the specific soil conditions of the jurisdiction. This study aimed to define the optimal sieving conditions for a sandy environment when searching for minute traces of paint, glass, hair and fibres. Furthermore, this study justifies the practice of retaining grave fill and examining it under controlled laboratory conditions, rather than in-situ adjacent to the grave site. The results demonstrate that using sieve mesh sizes as fine as 0.1 mm can recover up to 82% of the deposited traces and almost all paint, hair and glass traces. The processing of grave fill in the laboratory lead to increased yield of forensic evidence, which on a case-basis may warrant the increased time needed. These findings merit consideration for clandestine grave crime scenes where evidence is scarce or the case is likely to become cold.

Ground penetrating radar and electrical resistivity tomography surveys with a subsequent intrusive investigation in search for the missing Beaumont children in Adelaide, South Australia.

Jane, Arnna, and Grant Beaumont went missing from Glenelg Beach in Adelaide, South Australia on 26 January (Australia Day) 1966. Despite multiple land and sea searches over nearly 60 years, the children have not been found. New credible eyewitness testimony led to a site of interest at the now disused New Castalloy factory in North Plympton, Adelaide. This site has a complex stratigraphy of anthropogenic fill, which made ground penetrating radar (GPR) investigations unpromising. Electrical resistivity tomography (ERT), while not commonly used in a forensic capacity, provided an alternative approach that allowed suitable depth penetration to resolve a feature of interest, which was subsequently excavated by the South Australia Police. This feature did contain organic, and animal remains but, sadly, not the grave of Jane, Arnna, and Grant Beaumont. However, this investigation highlights the potential to use ERT in a forensic capacity, as well as the limitations of using geophysical techniques for covert burial detection.
