Unveiling the Nexus: Exploring the Influence of Personal and Situational Traits on Weapon Selection and Severity of Violence

Psychopathology and weapon choice: A study of 103 perpetrators of homicide or attempted homicide

This study examined the correlations between victim/offender relationship and three variables: motive, weapon choice, and number of injuries inflicted. Empirical relationship and motive categories were used. The sample consisted of 57 intentional homicide cases from Florida Medical Examiner District 8 between the years 1992 and 1996. Relationships were divided into primary and secondary categories. Primary relationships included intimates, relatives, and friends; secondary relationships included acquaintances and strangers. Motives were classified as romantic dispute, argument/conflict, revenge, or felony type; weapons as firearm or contact; and number of injuries inflicted as single or multiple. A significant correlation was found between victim/offender relationship and homicide motive; however, the revenge and felony type motive categories did not differ. Unexpectedly, no correlation was found between victim/offender relationship and either weapon choice or number of injuries inflicted. Further study is needed of the interactions between homicide victim/offender relationship and motive, weapon selection, and number of injuries inflicted.

The offender profiling process is an investigative technique used to identify the major personality and behavioural characteristics of the offender based upon an analysis of the crime(s) he or she has committed (Douglas & Burgess, 1986). Attempts have been made in both England and America to classify rapists into various subgroups. Instead of definitive groups of offenders a suggestion is made as to the formation of a dimensional typology of rapists. This would allow for the difficulties in defining boundaries for subgroups and accounting for individual differences and heterogeneity of both the rapist and the assault. The various criteria that attempt to distinguish the different types of offender are discussed including behavioural and motivational characteristics of the offender, lay theories of rape and the victim-offender relationship. The implications of the dimensional typology are outlined. There are indications that some factors may contribute to a longer and more complicated recovery process. Macnab (1993) neatly outlines eleven contributory factors: financial stress, various long term stresses, the degree of violence, the use of weapons, the sense of violation, the threat of death, multiple assailants, threats of greater or continuing harm and a later death, medical complications, problems with police, medical and criminal systems and lack of adequate professional and informed support. As well as this, the important issue of self-blame is discussed along with the subsequent problem of post-traumatic stress disorder: the recurring distressing memories, dreams and events and signals that can provoke a further cycle of distress.

The concept that weapon choice and use may play a valuable role in differentiating between offenders is one that has not been well explored in current criminological or psychological thinking. The key aim of the current paper is to discuss the role of weapon choice and use in the application of offender profiling. Relevant research is identified though a literature review: initially considering a broad range of offences and then narrowing the focus on the specific case of violent and sexual offences. The review highlights several key findings which are then conceptualised through the offender profiling literature. In the discussion, the paper argues that there is considerable merit in the consideration of weapons within profiling violent and sexual offenders and concludes with proposed dimensions (planning and emotional use of the weapon) that illustrate the range of motivations that may aid in discriminating offenders.

This study aimed to investigate main and interaction effects of situational (competition phase, match location, match status and match period), individual (penalty taker’s footedness, playing position, and age difference to the goalkeeper), and performance factors (shot direction and goalkeeper’s action) on penalty kick outcome in UEFA Champions and Europa leagues. Data were collected from soccer Internet sites and TV broadcasts during five consecutive seasons (from 2010-2011 to 2014-2015). A total of 536 penalties were recorded and analysed considering the aforementioned three groups of variables and the respective penalty outcome (goal, saved or missed). Multinomial logistic regression analysis was used to assess the effects of factors on penalty outcome. The logistic regression model revealed the probabilities of penalty kicks being saved significantly increased (1) in the middle of matches (30:01–60:00) and (2) when the shots were directed to lower zones of the goal, in particular to the lower centre-left zone of the goal (penalty taker’s perspective). Besides, the odds of missing the penalty substantially increased when the shot aimed the high zones of the goal. Based on the current findings, penalty takers should be encouraged to direct the shot to the upper corners of the goal and goalkeepers should wait longer in order to dive to the correct side of the ball. Although performance factors were the most decisive for determining the penalty outcome, situational factors such as match period may also influence the success of penalty kicks.

Strangulation‐related homicides represent a complex and under‐researched form of violent crime, characterized by distinct behavioral and situational elements. The aim of the research was to identify perpetrator typologies in strangulation homicides and to analyze their relationships with victim characteristics and crime scene factors. A retrospective analysis of 200 systematically sampled cases from the Radford/Florida Gulf Coast University Serial Killer Database employed Smallest Space Analysis (SSA) to examine 42 behavioral variables. The analysis revealed four primary typologies: Excessive (characterized by severe violence beyond lethality, including mutilation and torture), intended (marked by premeditation and organizational elements), personal (distinguished by intimate engagement and direct manual methods), and sexual (defined by sexual assault and sadistic behaviors). Statistical analysis demonstrated significant correlations between offender–victim relationships, crime scene characteristics, and degrees of violence within each typological category, with 97% of cases fitting distinctly into one category and 3% showing hybrid characteristics. The findings provide empirically based frameworks for forensic profiling and inform specific investigative strategies aligned with each typological pattern. These results equip law enforcement with targeted investigation and risk assessment approaches, potentially leading to more accurate offender identification and prevention efforts. The research advances the understanding of psychological and situational factors in strangulation‐related homicides, contributing to both forensic literature and practical applications in criminal investigations.

Purpose Weapon use is as risky in prison as it is in the community, but the type, use and meaning of weapons differ between these settings. Consequently, knowledge about community-based weapon violence may not generalise to prison contexts. The purpose of this study is to understand the meaning and use of weapons in a prison setting. Design/methodology/approach Using a framework for understanding weapon selection derived from a community setting, six prisoners in a remand setting in England who had a history of weapon possession and use in prison discussed their selection and use of weapons in prison. Findings Respondents described a hyperviolent milieu for some in which access to weapons was essential and wherein the official consequences of weapon carrying were outweighed by the potential costs of victimisation. Weapons served a variety of purposes for prisoners. At the individual level, they reduced the uncertainty of a hyperviolent environment, and they were used to construct and manage a violent identity as an aggressive precaution against victimisation. Originality/value This study develops the literature on weapon decision-making, extending it into a novel setting and addresses a significant gap in the prison research literature about the meaning and utility of weapons in a custodial setting. The use of a community-derived framework for understanding weapon carrying translated well into a prison environment and offers support for the synthesis of community and prison models of violence but distinctive features of the prison environment, such as how weapons are acquired, limits the fit of the model to a prison setting.

Violence is described as the intentional use of physical force against a person, oneself, or a group of people that causes trauma, psychological harm, or even death. It could take the shape of physical or psychological harm, deprivation, or emotional or sexual assault. Violence of many different kinds is committed in jails globally. However, they are frequently carried out in secrecy, which makes them challenging to establish. The target population for the study were prisoners and staff in Mogadishu Central Prison. A descriptive cross-sectional research design was applied to collect both quantitative and qualitative data. Systematic sampling was used to select prisoners, while purposive sampling was used to select key informants (staff). The study used questionnaires and key informant interviews as data collection tools. Quantitative analysis was conducted using SPSS version 27, and both Fisher’s exact test and Pearson’s Chi-square were used to test for associations and relationships between variables after descriptive analysis had been done. Qualitative analysis was conducted using thematic analysis. The study found that the overall prevalence of physical violence in the prison was 16.3%, with the majority of violence being conducted by convicts against other inmates, but there were also instances of violence committed against and committed by prison staff. The prevalence among inmates was 15%, and prisoners against warden was 1.3%. The most common types of physical violence were fist fights (11.8%), flogging (1.6%), use of weapons or other instruments (1.6%) such as razor blades, throwing shoes at each other, or use of finger rings and slapping (1.3%). The study highlights a concerning high prevalence of physical violence within Mogadishu Central Prison, primarily perpetrated by inmates against each other and occasionally involving prison staff. To address the issue, the study recommends a multifaceted approach, including heightened conflict recognition and resolution training for prison staff, increased investment in resources to alleviate overcrowding, and the establishment of rehabilitation and mental health programs to target the underlying triggers of violence

The following paper presents a case study of a convicted serial murderer. Through data from personal correspondence, police reports, a true crime novel, witness statements, medical examiner reports, court appeals, and crime scene reports from the actual murder cases, and most important, a series of psychological self‐report measures, a case study was developed. Included in the psychological measures were tests of general psychopathology, specific tests of psychopathy, anger and aggression scales, and sociological measures related to family, individual, situational, and community risk factors, as well as previous criminal behaviour, including weapon and drug use. The results of these various measures are incorporated into the life history and criminal activity of the individual. The purpose of this research was to develop a more complete psychological report of a serial killer than any other previously reported. Copyright © 2010 John Wiley & Sons, Ltd.

Existing research provides no systematic insights into if and how mediation impedes battle-related deaths. Therefore, this article presents a temporally disaggregated analysis and assesses the effect of mediation on monthly fatal violence. The article predicts that adversaries evaluate opponents’ trustworthiness from both fighting and negotiation behavior. It argues that reducing fighting intensity during negotiations is a sign of cooperation, which can be negotiated by mediators to build trust. Over the course of mediation, the content of negotiations provides information about how genuinely a conflict party is interested in conflict resolution. Only if mediation achieves negotiation of core incompatibilities will conflict parties be willing to reduce fighting intensity. Under these conditions, information revealed in a mediation process can build trust and substantively reduce violence. An empirical analysis of all African conflicts between 1993 and 2007 supports this prediction and shows that on average mediation is followed by substantive and lasting reductions in fatal violence, if mediation discusses the conflict’s main incompatibility. In contrast, mediation on other topics is associated with a small, fleeting reduction in violence. Data of battle-related fatalities in Syria during negotiations as well as qualitative evidence further support the theoretical mechanism and the model prediction. The study concludes that mediation can reduce conflict intensity substantively, if it achieves exchange between conflict parties on the main conflict issues.

In the vast literature on terrorism the choice of weapons has received relatively limited attention, despite the importance and visibility of this topic. Building on the literature on innovation in terrorism, the article first proposes a multi-level analytical framework that helps study terrorist weapon selection. It then investigates the use of weapons in jihadist attacks in Europe from 2014, with the rise of the so-called Islamic State, until 2020, based on an original database. The empirical analysis shows that the two traditional types of weapon of modern terrorism, firearms and explosives, were largely replaced by more primitive tools like melee weapons. In fact, in recent years jihadist terrorists in Europe have become less technologically advanced. Based on the original analytical framework, the article examines the reasons of this evolution, paying special attention to the use of the most common type of weapon in the database, bladed weapons, and the most lethal type, firearms.

Intimate partners commit approximately one in three homicides against women worldwide. Little is known about situational factors that contribute to intimate partner homicides (IPH) and how they may differ across nations. This article provides a cross-national exploration of one situational factor, the use of firearms in the commission of homicides, and considers whether nations have laws designed specifically to keep firearms out of the hands of batterers. We conducted a systematic search of peer-reviewed research and governmental and nongovernmental reports for data on weapon use in IPH. Data were located for 15 nations and subnational areas, which varied from firearms being involved in no IPHs in Fiji to 59% in Antalya, Turkey. Seven nations have legislation that addresses gun ownership as it relates to those who have been charged with, convicted of, or show a propensity toward the commission of intimate partner violence. These laws vary in whether domestic violence is a factor considered in whether to allow firearm ownership or whether it served to disqualify ownership. Due to the small number of nations for which data on weapon use in IPH were located, we did not conduct any hypothesis testing. There is a need for detailed homicide surveillance systems among nations so that researchers can explore the epidemiology of these homicides and ultimately identify opportunities for intervention.

The Roles of Personality Traits and Negative Life Events on the Episodes of Depressive Symptoms in Nonreferred Adolescents: A 1-Year Follow-Up Study

The dangerousness of domestic violence escalates when suspects use weapons against victims or responding officers. Nevertheless, only a few studies have examined the dynamics of weapon use in domestic violence. While supporting the situational approach, the limited literature and relevant theories suggest the need for weapons classification and multilevel research. Using over 9,400 domestic violence cases across 423 census tracts that were responded to by the Houston Police Department in 2005, hierarchical linear models examine the correlates of weapon use by suspects. Results indicate that situational and neighborhood factors are distinctively associated with each type of weapon. Implications for future research and policy are discussed.

Objectives: To test the hypothesis that weapon-related violence (excluding firearms) results in more severe injury relative to the use of body parts (fists, feet and other body parts), and to...
