Results indicated that access to case details prior to the interview did not significantly influence the type or quality of questions asked within the interview itself but significantly influenced interviewers' memories for their interview 1 week later. Those who were blind to case information at the time of the interview had more accurate memories of their witness interviews than those who were correctly or incorrectly pre-informed.

We administered biased line-up instructions to 50% of participants to investigate how this impacted choosing behaviour and accuracy. Based on 1030 line-up decisions (<i>N</i> = 122), we found that average accuracy was 38% in target present (TP) and 54% in target absent (TA) line-ups and that biased line-up instructions decreased overall accuracy (vs. unbiased). The hit rate for TP line-ups with biased instructions was 0.43 (unbiased instructions: 0.33), while the false alarm rate for TA line-ups with biased instructions was 0.60 (unbiased instructions: 0.32). We found that high confidence was associated with correct identifications and that shorter response times were indicative of correct rejections.

To date, there is no working model for differentiating male femicide offenders within Northern Ireland (NI); therefore, the current study aimed to do this, focusing on the timeframe of the COVID-19 lockdown in 2020. The research has drawn on newspaper articles reporting on the 11 NI femicides perpetrated over a period of 20 months. These crimes were content analysed for the presence or absence of 16 pre-identified offender variables. The data was analysed using a multi-dimensional scaling procedure called Smallest Space Analysis (SSA). Two distinct themes emerged: <i>Chronic Criminal Abuser</i> and <i>Mentally Disturbed</i>. The qualitative data obtained on offender characteristics aligned with the preliminary model for differentiation. Forensic implications pertinent to risk assessment and management are considered. It is argued that NI adopt an active violence against women and girls (VAWG) strategy to effectively tackle the issue of Femicide.

In this research, we focus on the so-called Dark Triad personality, consisting of the Machiavellian, the narcissistic and the psychopathic personalities. The main objective of this study was to examine the association between Dark Triad personality and psychopathology and also to know the role of these mental health variables in recidivism. Participants were 63 offenders (44 men and 19 women) from two different penitentiary institutions. Sociodemographic data as well as clinical and personality characteristics were recorded. Psychopathology was assessed with the third version of the Millon Clinical Multiaxial Inventory and dark personality with the Short Dark Triad. Results of descriptive statistical analyses revealed a high prevalence of psychopathology in convicted participants and reincarcerated offenders. Correlational analyses showed a strong relation between the Dark Triad personality and psychopathology, being the psychopathic personality the one with the highest association. Finally, we found that the psychopathological variables contributing most to the discrimination of reincarcerated participants were substance and alcohol abuse disorders and in relation to dysfunctional personality were psychopathy and narcissism, the latter in negative direction. These data highlight the relevance of a necessity for research exploring long-term patterns of re-incarceration for both men and women, including mental health disorders and personality models.

While psychiatric and evolutionary theories have been predominantly used in the filicide literature, prior works have neglected to examine how culture shapes violence against one’s offspring. This paper explores the offence, offender, and victim characteristics in South Korean filicides (1948–1962) through a content analysis of a major newspaper (<i>Chosun Ilbo</i>). Results indicate that filicides occur in one-on-one contexts, primarily carried out by biological parents against their offspring while adoptive children appeared as victims due to the genealogical customs practiced in Korean society.

Findings reveal that SH cases with unusual acts present a specific crime-commission process.
