Late-stage borreliosis and substance abuse.

Background: Infectious diseases can contribute to substance abuse. Here, a fatal case of borreliosis and substance abuse is reported. This patient had a history of multiple tick bites and increasing multisystem symptoms, yet diagnosis and treatment were delayed. He experimented with multiple substances including phencyclidine (PCP), an N-methyl-d-aspartate (NMDA) receptor antagonist that opposes NMDA agonism caused by Borrelia infection. During PCP withdrawal, he committed one homicide, two assaults, and suicide. Methods: Brain tissue was obtained from autopsy and stained for microglial activation and quinolinic acid (QA). Immunoflouresence (IFA) and fluorescence in situ hybridization (FISH) were used to identify the presence of pathogens in autopsy tissue. Results: Autopsy tissue evaluation demonstrated Borrelia in the pancreas by IFA and heart by IFA and FISH. Activated microglia and QA were found in the brain, indicating neuroinflammation. It is postulated that PCP withdrawal may exacerbate symptoms produced by Borrelia-induced biochemical imbalances in the brain. This combination may have greatly increased his acute homicidal and suicidal risk. Patient databases also demonstrated the risk of homicide or suicide in patients diagnosed with borreliosis and confirmed multiple symptoms in these patients, including chronic pain, anxiety, and anhedonia. Conclusions: Late-stage borreliosis is associated with multiple symptoms that may contribute to an increased risk of substance abuse and addictive disorders. More effective diagnosis and treatment of borreliosis, and attention to substance abuse potential may help reduce associated morbidity and mortality in patients with borreliosis, particularly in endemic areas.

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.

The Spatial Scale and Spread of Child Victimization.

Previous research shows that large, densely populated urban areas have higher rates of child victimization that have persisted over time. However, few investigations have inquired about the processes that produce and sustain hot and cold spots of child victimization. As a result, the mechanisms that produce the observed spatial clustering of child victimization, and hence "why" harms against children tend to cluster in space, remains unknown. Does the likelihood of being a victim of violence in one location depend on a similar event happening in a nearby location within a specified timeframe? Rather, are child victims of violence more likely to reside in suboptimal neighborhood conditions? This paper aims to present an analytical and theoretical framework for distinguishing between these locational (point) processes to determine whether the empirical spatial patterns undergirding child victimization are more reflective of the "spread" via contagion (i.e., dependency) or whether they are produced by neighborhood structural inequality resulting from spatial heterogeneity. To detect spatial dependence, we applied the inhomogeneous K-function to Los Angeles Medical Examiner data on child homicide victim locations while controlling for regional differences in victimization events (i.e., heterogeneity). Our analysis found strong evidence of spatial clustering in child victimization at small spatial scales but inhibition at larger scales. We further found limited support for the spatiotemporal clustering of child victimization indicative of a contagion effect. Overall, our results support the role of neighborhood structural vulnerability in the underlying mechanisms producing patterns of child victimization across Los Angeles County. We conclude by discussing the policy implications for understanding this spatial patterning in geographical context and for developing effective and targeted preventive interventions.

Crime-scene and offender characteristics in conventional and nonconventional stranger homicides committed by male offenders in Sweden.

In Sweden, from 1990 to 2013, most homicides occurred between family members, friends or acquaintances: the annual rate of incidents between unacquainted offenders and victims ranged between 8% and 13%. In the majority of these "stranger homicides," three common motives, as defined by the precipitating event, could be identified: homicides resulting from a spontaneous altercation; homicides committed in the context of a robbery or burglary; and homicides committed in the context of a gangland conflict. The remaining minority-with uncommon or indiscernible motives-could, nonetheless, be categorized according to their nonconventional distinguishing feature: homicides characterized by the offender's ostensibly mentally aberrant behavior; homicides committed in the context of a hate offense or politically motivated offense; homicides committed in the context of a sexual offense; and homicides committed in the context of a mass killing or series of homicides. In this registry-based study of 224 incidents, "conventional" stranger homicides, defined by their commonplace motive, were compared with "nonconventional" stranger homicides, defined by their lack of such motive. The former were more often committed with an accomplice, against a male victim, whereas the latter were more often committed in a public place, after contact initiated by the offender. In the latter, offenders were less often intoxicated at the time of the offense and more often adjudged to suffer from a severe mental disorder. The subcategory of nonconventional stranger homicides characterized by the offender's ostensibly mentally aberrant behavior corresponded largely to both the archetypal stranger-homicide construct and the popular notion "act of madness."

Counting the days: Exploring the post-mortem interval factors in sexual homicides.

This study explores the offender, victim, and environmental characteristics that significantly influence the number of days a sexual homicide victim remains undiscovered. Utilizing a sample of 269 cases from the Homicide Investigation Tracking System database an in-depth analysis was conducted to unveil the factors contributing to the delay in the discovery of victims' bodies. The methodological approach involves applying a negative binomial regression analysis, which allows for the examination of count data, specifically addressing the over-dispersion and excess zeros in the dependent variable - the number of days until the victim is found. The findings reveal that certain offender characteristics, victim traits, and spatio-temporal factors play a pivotal role in the time lag experienced in locating the bodies of homicide victims. These findings have crucial implications for investigative efforts in homicide cases, offering valuable insights that can inform and enhance the efficacy and efficiency of future investigative procedures and strategies.

Exploring bereavement processes among BLACK adolescent male CO-VICTIMS of homicide.

Black adolescent males are disproportionally impacted by violence exposure and violent loss. The primary aim of this study was to explore the bereavement experiences of Black adolescent males who have lost a friend or family member to murder. Participants were Black adolescent males between the ages of 14-19 years. This was a purposive sample recruited from a community-based study that took place in urban neighborhoods in Pittsburgh, Pennsylvania. Participants who completed their final survey for the parent study were recruited from January to June 2017. Participants completed a brief computerized survey and those who responded affirmatively to a screening question about losing a friend or family member to murder were invited to a qualitative interview. Interviews were audio recorded, transcribed, and coded to identify key themes. Among the 31 youth interviewed, 30 had lost more than one person to murder. Four primary themes emerged from their narratives: (1) self-preservation through isolation, (2) finding sanctuary through shared narratives of loss, (3) freedom from the mind, and (4) post-traumatic growth (i.e., motivation, healing, resilience). Findings suggest that interventions that provide sanctuary for youth that are culturally relevant and create opportunities for youth to process violent loss may aid in promoting opportunities for youth to grieve and heal from violent loss.

Comparing child and adult sexual homicides in Australia and New Zealand: A retrospective study.

The present study examined distinctions between child (n = 30) and adult (n = 212) sexual homicide offenders (SHOs) in Australia and New Zealand, contributing to the limited international research on the subject. Data, primarily sourced from judges' sentencing comments on AustLII and New Zealand Legal Information Institute, revealed significant differences. Child SHOs displayed elevated rates of pedophilia, sexual deviance, and adverse childhood experiences, including sexual abuse. They were more likely to be married, cohabitate, and target familial victims. Their crimes were more often committed during daylight and outdoors, involving tactics such as victim conning, restraints, strangulation, and hiding victim's bodies. No significant group differences emerged regarding offenders' psychopathy or sexual sadism scores. Results were interpreted in line with child SHOs' deviant sexual preferences and the routine activity theory. The study, as the first investigating child sexual homicides in Australia and New Zealand, sets the foundation for an evidence-based approach to policy and practice.

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.

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.

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.

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.

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.

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.

Superhomicide offenders: Nosology, empirical features, and linkages to sexual and multiple murder typologies.

The nosology for criminals who murder multiple victims is at once well-established and controversial, perhaps because theorists have largely segregated such offenders from the broader criminal population. The current study introduces the superhomicide offender, an individual convicted of at least five murders, to locate multiple homicide offenders within the criminological and epidemiological science pertaining to the most pathological offenders, and statistically place them with other conceptualizations of severe offenders at the 95th percentile of the offending distribution. Relative to other capital murderers, superhomicide offenders have lengthier criminal history, greater conviction history, and coextensive psychopathology characterized by psychopathy, sexual sadism, homicidal ideation, cluster A and B personality disorders, and major depressive disorder. Superhomicide offenders are profoundly psychopathic with 20 of the 39 offenders reaching the clinical threshold of 30 or more on the PCL-R, and 19 of the 39 are sexually sadistic. Regarding extant typologies of sexual and multiple homicide offenders, 15 are serial murderers, 17 are sexual homicide offenders, 17 are mass murderers, and 17 are spree murderers. Twenty-four of the 39 superhomicide offenders (61.5%) met criteria for multiple typologies, suggesting the new prototype can help unify the study of those who perpetrate multicide and embed them within criminological and epidemiological models that specify pathological antisocial outcomes.

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.

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.

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.

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.

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.
