The relationship between personality, behavioral cues, and the ability to tell a convincing lie was examined. Participants were administered the M5-120 personality inventory and videotaped while retelling a partially scripted story. A group of raters reviewed the video clips and decided whether the participants were lying or being honest. Findings revealed a significant relationship between successful lying and the Agreeableness domain of personality. Specifically, the modesty and sympathy facets of the Agreeableness domain were significantly correlated with successful lying. These results suggest that personality may play a role in the ability to successfully lie. In addition, significant correlations were demonstrated between body language and successful lying and between facial expressions and successful lying.

Victims can provide details necessary to resolve criminal investigations but may be reluctant to come forward and fully disclose an incident to law enforcement. Although evidence-based interviewing techniques such as rapport-building have shown promise in increasing cooperation, the potential impact of interviewers' inherent characteristics (e.g., age and gender) on information disclosure has been relatively under examined. We investigated mock sexual assault victims' preferences for various police interviewer characteristics and the impact of these preferences on hypothetical reporting behaviour. Participants rated interviewers' interpersonal skills as highly important. Gender differences were observed, with only female participants consistently reporting that having a same-gender interviewer was important. Participants also indicated that if they were provided with their preferred interviewer, they would feel more comfortable, provide more detail, and would be more willing to report the offence to police. Our findings suggest that matching interviewees with their preferred interviewers may improve interviewing and investigative outcomes.

The purpose of this study is to develop an evidence-based set of inductive profiles based on matched victim-offender characteristics of homicide cases. To develop these homicide profiles, we used national data from the FBI's supplementary homicide reports that were reported by law enforcement agencies for a period of 42 years, from 1976 to 2017 in the United States. The findings that emerged from the study show that female offenders tend to kill victims of the opposite gender; whereas male offenders kill more victims within their own gender. The probability of becoming a victim of homicide increases for white people and decreases for black people as the offender's age increases. Overall, offenders tend to kill victims about their own age, and as offenders get older, they are more likely to kill female victims than male victims.

During the COVID-19 pandemic, police officers have been at the frontline of danger. Their mental health should arouse the attention of society. To test the relationship between the psychological support they received and their stress response, the present study built a moderated mediation model to examine this and the effects of underlying mechanisms. A total of 553 Chinese police officers participated in this study; four scales were measured by standardised questionnaires (Emotional Identity of Profession Scale; DSM-5 Self-Rated Level 1 Cross-Cutting Symptom Measure-Adult; Psychological Support Scale; Active Work Adaptation Scale). Stress response was negatively correlated with psychological support, emotional identity of profession and active work adaptation. Psychological support, emotional identity of profession and active work adaptation were all positively correlated. Psychological support had a negative direct effect on stress response, and emotional identity of profession's mediating effect was distinct and was moderated by active work adaptation.

In this study, the displacement of 687 murderers in Spain (2010–2012) is analysed. The Euclidean distance between the offender's residence and the furthest scene related to the event has been calculated. The analyses showed that the murderers registered a displacement of 0.5 km, with 255 cases of non-traveller homicide (37.1%). The bivariate analysis found that men, young and foreign, with a criminal record and unrelated to the victim, registered a large distance, as well as multi-offender homicides and were related to criminal activities. Traveller homicide registered a displacement of 4.3 km, with adults unrelated to the victim travelling the farthest. Multi-offender and crime-related homicides continued to show the largest distance. Multivariate analyses showed that if the offender is foreign, has no previous relationship with the victim and there are several offenders involved, the distance will be larger. When only traveller homicides were analysed, only the type of relationship showed significant differences.

Over 320,000 missing persons are estimated to go missing annually in United Kingdom due to a variety of intentional and unintentional factors. This article aims to investigate whether the criminal narrative experience framework can be applied to missing persons to acquire a deeper insight into the psychological differences between missing children. Sixty-one previously missing persons completed a missing experience survey, narrative roles questionnaire, and emotions questionnaire. Data were content analysed and subjected to a non-metric, multi-dimensional scaling procedure in the form of smallest space analysis. The results identified four distinct behavioural themes as follows: depressed throwaway victim, distressed pushaway revenger, calm runaway professional and elated fallaway hero. Following a stringent criterion, 88.50% of the sample could be differentiated into one dominant behavioural theme with the remaining 11.50% identified as a hybrid theme. Due to the exploratory nature of the study, additional exploration of the applicability of the framework is required.

Quite possibly, the first application of geographic analysis to identify and characterise the spatial behaviour of the offender concerning the crime scene was developed in 1980 by Milton Newton. Although previous studies have used Newton and Swoope's geoforensic process (Kent, 2009, Essays on the integration of anisotropic landscapes within contemporary geographic profiling models [LSU doctoral dissertations]; Leitner et al., 2007, Police Practice and Research, 8[4], 359–370) to verify the effectiveness of the algorithm, there are, to our knowledge, no investigations that have validated the procedure with cases of serial murderers. The main objective of the study is to analyse a sample of 41 serial killers with a minimum number of six crimes and to evaluate the method proposed by Newton (1988, Geographical discovery of the residence of an unknown dispersing localized serial murder). The results confirm only Newton's first assumption in which after the fifth crime in the series, the estimated ‘haven’ is close to the actual ‘haven’, ruling out that the search area becomes progressively smaller and that the ‘haven’ is located in the search area.

Investigators need to elicit detailed statements from interviewees to find potential leads, whilst simultaneously judging if a statement is genuine or fabricated. Researchers have proposed that the Model Statement (MS) can both (a) increase information elicitation from interviewees and (b) amplify the verbal differences between liars and truth tellers, thereby enhancing lie-detection accuracy. Based upon a critical analysis of the MS literature, we argue that this tool is not currently ready for practical usage, as its utility has not been fully established. We highlight a diverse range of existing MS scripts, and a greater diversity in the dependent measures examined in conjunction with this tool. More robust replications of these procedures are needed. We also highlight why some measures of verbal content may not be suitable as outcome measures and suggest that new research could use the well-established reality monitoring criteria to allow for standardisation across studies.
