The purpose of this study is to investigate whether sexual homicide offenders (SHO) who dispose of the victim’s body naked present with particular crime scene characteristics.

This study aims to answer this question through the use of a sequential logistic regression to test the individual effects of each set of crime scene variables against the manner of disposal using a sample of 662 solved cases of extrafamilial sexual homicide from an international database.

Results demonstrated that the modus operandi behaviors of sexual penetration, asphyxiation, dismemberment and overkill were significantly associated with the body being disposed of naked. In addition, removing or destroying evidence from the scene was also significantly associated with a naked victim. In contrast, the body was more likely to be dumped clothed if the contact scene was deserted and the victim was a stranger. These results suggest that SHOs who dispose of the body naked are more in line with the sadistic sexual murderer, while clothed victims are often disposed of by angry offenders.

To the best of the authors’ knowledge, this is the first study to examine the particular manner of disposing the victim’s body naked in cases of sexual homicide.

Reports from 2016 to 2017 suggest that approximately 870 cases of non-familial child abduction (NFA) are recorded in England and Wales per year. Yet, empirical knowledge of the victims, offenders and offence characteristics is limited in comparison to other forms of child victimisation. Furthermore, much of the available knowledge is constrained by a lack of clarity around the differences between acquaintance and stranger abductors. This systematic literature review aims to develop a comprehensive overview of acquaintance and stranger child abductions, focussing on the similarities and differences in offending behaviours.

Research databases (PsycArticles, Google Scholar, Science Direct, PsycINFO, Criminal Justice Abstracts, MEDLINE and ERIC) and the Grey Literature (ETHOS and EBSCO) were screened for peer-reviewed research published between 1995 and 2021. Sixteen articles met the inclusion criteria and were critically appraised using a modified version of the Joanna Briggs Institute Checklist for Case Reports.

Six key areas within NFA offences and their characteristics were identified as offering potential for differentiating acquaintance and stranger abductors: victim–offender relationship, number of victims and offenders, motives, modus operandi, victim injury, sexual assault and mechanism of death (in fatal cases). The results of this review are discussed with consideration given to investigative implications, limitations and directions for future study.

To the best of the authors’ knowledge, this paper is the first to systematically review the current NFA literature, from which pragmatic recommendations for practice and future academic enquiry are drawn.

The purpose of this paper is to address the complexity of missing persons cases and highlight the linguistic differences that arise in this type of crime. Missing persons cases are typically very complex investigations. Without a body, crime scene forensics is not possible, and police are often left only with witness and suspect statements. Forensic linguistics methods may help investigators to prioritise or remove suspects. There are many competing approaches in forensic linguistic analysis; however, there is limited empirical research available on emerging methods.

This research investigates Statement Analysis, a recent development in linguistic analysis that has practical applications in criminal investigations. Real-world statements of individuals convicted of or found to be not guilty of their involvement in missing persons cases were used in the analyses. In addition, Behaviour Sequence Analysis was used to map the progressions of language in the suspects' statements.

Results indicated differences between the guilty and innocent individuals based on their language choices, for example, guilty suspects in missing [alive] cases were found more likely to use passive language and vague words because of high levels of cognitive load associated with the several types of guilty knowledge suspects in missing persons cases possess. Of particular interest is the use of untruthful words in the innocent suspects’ statements in missing [murdered] cases. While typically seen in deceptive statements, untruthful words in innocent statements may result because of false acquittals.

This research provides some support for Statement Analysis as a suitable approach to analysing linguistic statements in missing persons cases.

This study aims to examine the scope and contribution of Forensic Clinical Psychology (FCP) advice from the National Crime Agency (NCA) to criminal investigations in the UK to address the gap in current knowledge and research.

The 36 FCP reports reviewed were written between 2017 and 2021. They were analysed using Toulmin’s (1958) application of pertinent arguments to the evaluation process. The potential utility of the reports was analysed in terms of the advice provided.

Most of the reports involved murder and equivocal death. The reports focused primarily on understanding the offender’s psychopathology, actions, motivation and risk to self and others using a practitioner model of case study methodology. Out of the 539 claims, grounds were provided for 99% of the claims, 91% had designated modality, 62% of the claims were potentially verifiable and 57% of the claims were supported by a warrant and/or backing. Most of the reports provided either moderate or high insight into the offence/offender (92%) and potential for new leads (64%).

The advice provided relied heavily on extensive forensic clinical and investigative experience of offenders, guided by theory and research and was often performed under considerable time pressure. Flexibility, impartiality, rigour and resilience are essential prerequisites for this type of work.

To the best of the authors’ knowledge, this study is the first to systematically evaluate forensic clinical psychology reports from the NCA. It shows the pragmatic, dynamic and varied nature of FCP contributions to investigations and its potential utility.

In addition to being a violation of human rights, the practice of child labor can be related to criminality against young people. In view of this, the hypothesis tested in this article was that child labor aggravates youth homicide through educational level.

This study used annual data for the 26 states plus the Federal District for the period 2001 to 2014. To do so, the authors used the iterated feasible generalized least squares (IFGLS) estimator under the seemingly unrelated regressions (SUR) model.

The results showed that child labor positively affects the homicide of young people, showing education as a transmission channel through which the effect is materialized. The general conclusion, given this, that work is an alternative for children not to enter the world of crime due to its socializing character, cannot be sustained.

This evidence provides input to the formulation of policies and programs to eradicate or slow child labor. In addition to the social and economic rise of individuals, it is important to emphasize the role of education (human capital) in explaining economic growth.

So far, there is no record of national research that sought to empirically assess the effect of child labor on crime, in particular, on the homicide of young people, considering education as a transmission channel, and this assessment is the contribution of the present study to the economic literature on crime.

The proliferation of recording technologies has increased the prevalence of police intervention videos in news media. Although previous research has explored the influence of such coverage on public opinion, the mechanisms underlying this impact have received limited attention. This study investigates the role of information credibility in the assessment of police interventions portrayed in news media videos.

A total of 634 participants were shown a mock-up TV news report that included a description and a brief clip of a police use-of-force event. A survey was conducted before and after the presentation of the report.

Camera perspective, anchor tone, viewer gender and pre-existing perceived TV news credibility were found to influence how credible the mock-up news report was perceived. Participants who judged the news report as complete and credible tended to have a more favourable opinion of the police intervention. Perceived credibility also acted as a moderator in the relationship between video and receiver characteristics and the assessment of the police intervention.

These findings offer valuable insights for law enforcement agencies and their public affairs units to develop effective strategies for managing public opinion.

This research highlights how important perceived credibility is in influencing public opinion and how different factors such as video and receiver characteristics can impact credibility assessment.

The present study aims to examine the scope and contribution of behavioural investigative advice (BIA) reports from the National Crime Agency (NCA).

The 77 BIA reports reviewed were written between 2016 and 2021. They were evaluated using Toulmin’s (1958) strategy for structuring pertinent arguments, current compliance with professional standards, the grounds and backing provided for the claims made and the potential utility of the recommendations provided.

Consistent with previous research, most of the reports involved murder and sexual offences. The BIA reports met professional standards with extremely high frequency. The 77 reports contained a total of 1,308 claims of which 99% were based on stated grounds. A warrant and/or backing was provided for 73% of the claims. Most of the claims in the BIA reports involved a behavioural evaluation of the crime scene and offender characteristics. The potential utility of the reports was judged to be 95% for informative behavioural crime scene analysis and 40% for potential new lines of enquiry.

The reports should serve as a model for the work of behavioural investigative advisers internationally.

To the best of the authors’ knowledge, this is the first study to systematically evaluate BIA reports commissioned by the NCA; it adds to previous similar studies by evaluating the largest number of BIA reports ever reviewed, and uniquely provides judgement of overall utility.

The present study examines the risk of citizens encountering police use of intermediate and deadly force, as opposed to using physical force, given a set of individual, situational and neighborhood variables.

The study uses data from 2003 to 2016 in the Dallas Open Data Portal. Two-level multinomial logistic regression is used to analyze the data.

The effects of citizen race differ across the types of police force. Overall, citizen race plays no significant role in the officer's decision to shoot firearms at citizens. However, there is evidence of intra-racial disparity in officer-involved shootings (OISs) between Hispanic citizens and officers. African American citizens are disproportionately exposed to display-but-don't shoot incidents, while Hispanic citizens have a lower risk of encountering police use of intermediate weapons.

The study helps to understand how citizen and officer race influence and interact across various types of police force. Implications of the results are offered in relation to relevant literature.
