With the escalating overdose epidemic, many surveillance efforts have appeared. In 2018, King County Medical Examiner's Office (KCMEO) initiated a fatal overdose surveillance project aimed at expediting death certification and disseminating timely information. In this project, KCMEO investigators collected items of evidence of drug use from overdose death scenes, which were tested by five in-house methods, four using handheld devices: TruNarc Raman spectrometer, with and without the manufacture's H-Kit, Rigaku ResQ Raman spectrometer, and MX908 mass spectrometer...

Pinacolyl alcohol (PA), a key forensic marker for the nerve agent Soman (GD), is a particularly difficult analyte to detect by various analytical methods. In this work, we have explored the reaction between PA and 1,1'-carbonyldiimidazole (CDI) to yield pinacolyl 1H-imidazole-1-carboxylate (PIC), a product that can be conveniently detected by gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-high-resolution mass spectrometry (LC-HRMS). Regarding its GC-MS profile, this new carbamate derivative of PA possesses favorable chromatographic features such as a sharp peak and a longer retention time (RT = 16...

This study explored the personal perspectives of youth correctional officers within secure and open custody facilities in Ontario. A multi-methods design allowed for quantitative data collection to assess demographics and scores on a relationship scale and qualitative open-ended survey responses to explore areas of interest regarding officer work. Despite a small sample size ( N  = 26), results indicated trends in officers' views of their work and relationships with youth. Youth officers report various job duties ranging from supervision/security to cleaning and preparing meals...

Ground truth data (GTD) is used by those in the field of digital forensics (DF) for a variety of purposes including to evaluate the functionality of undocumented, new, or emerging technology and services and the digital traces left behind following their usage. Most accepted and reliable trace interpretations must be derived from an examination of relevant GTD, yet despite the importance of it to the DF community, there is little formal guidance available for supporting those who create it, to do so in a way that ensures any data is of good quality, reliable, and therefore usable...

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...

BACKGROUND: Aggressive conduct among delinquents presents a pervasive issue, bearing substantial implications for not only society at large but also for the victims and the individuals displaying the aggression. Traditional approaches to treating aggression regulation deficiencies generally employ Cognitive Behavioral Therapy (CBT) in conjunction with analog role-playing exercises. A body of research supports the efficacy of various therapeutic models for aggression regulation, including Responsive Aggression Regulation Therapy (Re-ART)...

Technology-facilitated sexual abuse refers to the use of information and communication technologies to facilitate both virtual and in-person sexual crimes. Research on this topic has focused on rates, risk factors, and consequences. This scoping review aims to understand whether and how forensic psychological procedures are adapted to assess adolescent victims and how Internet-based information might be useful as complementary data. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extensions for Scoping Reviews guidelines, searches were conducted in April 2023 in five electronic databases to include Portuguese, Spanish, or English quantitative, qualitative, or mixed-method peer-reviewed studies...

Incarceration is one of the most stressful life experiences with negative impacts on the health and wellbeing of the prisoners. Sufficient studies exist on the association between religiosity and adjustment to prison (ATP) but no studies have investigated the mediating variables explaining this link. This study examined the mediating role of resilience on the relationship between religiosity and ATP. Participants 513 inmates (males = 410, females = 103; mean age = 30...

The ability to determine bullet trajectories after a shooting incident can allow investigators to reconstruct the locations of individuals and the sequence of events that took place. By using trajectory rods, investigators can be provided with an immediate visual estimate as to what the path of the projectile may have been. In certain instances, the use of the probing method with trajectory rods is not appropriate due to their being a single, thin target material, or no secondary bullet impact site. In these cases, other methods such as the lead-in or the ellipse method may be useful...

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...

INTRODUCTION: Overweight and obesity constitute a major concern among patients treated at forensic psychiatric departments. The present clinical feasibility study aimed at investigating the extent to which glucagon-like peptide 1 receptor agonist (GLP-1RA) treatment with once-daily liraglutide 3.0 mg could be a feasible pharmacological treatment of these conditions in patients with schizophrenia spectrum disorders hospitalised in forensic psychiatry. METHODS: The 26-week, open-label feasibility study included participants aged 18-65 years diagnosed with a severe mental illness and hospitalised at a forensic psychiatric department...

BACKGROUND: Women charged with violent offences may be referred by courts for forensic psychiatric assessment to determine whether mental disorder or intellectual disability impacts their fitness to stand trial and/or criminal responsibility. The profile of these women is a poorly researched area in South Africa. AIM: This study examined the socio-demographic, offence-related, and clinical profile of South African women charged with violent offences referred for forensic assessment...

BACKGROUND: Trauma experiences, particularly in childhood, have been associated with criminality and mental illness. There is a paucity of research into the crime of murder, trauma and mental illness. AIM: This research study focused on state patients charged with murder and sought to determine associations with prior trauma experiences, and specific types of traumas (sexual, physical and emotional). SETTING: The study was conducted at a forensic psychiatric hospital in Johannesburg, South Africa...

BACKGROUND: Globally, crime is highly masculinised and research into female criminality is scarce. In South Africa, no research specifically investigating the characteristics of female observandi referred for non-violent crimes has been published. AIMS: The study aimed to describe the socio-demographic, clinical, and forensic correlates in women referred to Sterkfontein Hospital for forensic psychiatric observation following a non-violent criminal charge between 2010 and 2019...

Mental health professionals are tasked with making difficult clinical decisions in treatment settings. In the forensic system, decision making regarding staff supervised community outings (SSCOs) provides a significant challenge due to the need to balance patient liberties, mental health recovery, and public safety. This study explored the characteristics and rehabilitative nature of SSCOs, characteristics of patients attending SSCOs, and any adverse events that occurred during the outings. Employing a cross-sectional design, 110 patients who participated in SSCOs over a one-year period from a Canadian Forensic Psychiatric Hospital were included...

The current article provides a contemporary review of the best practices for interviewing older adults about crimes they witnessed or experienced. Specifically, we provide a detailed overview of how investigators can use a range of interviewing adaptations and procedures to acquire detailed and accurate maltreatment disclosures from older adults. In addition to discussing well-established investigative interviewing practices (e.g. rapport building, free-recall, cognitive instructions and prompts), this article also summarizes more recent literature on the benefits of multidisciplinary investigations, use of assistive technology and interview accommodations, along with effective practices for working with minority and marginalized older adults...

The ceiling of therapeutic security in Aotearoa New Zealand is medium security. The aim of this study is to identify and characterise a putative cohort of high-secure patients at a medium-secure regional forensic mental health service. A retrospective review of all admissions to a specific service was conducted over 3.75 years. The Dangerousness Understanding, Recovery and Urgency Manual, Triage Security Scale (DUNDRUM-1) was used to identify patients with high-secure care needs. A multiple logistic regression analysis was used to identify the local needs of this cohort...

Child eyewitnesses show a high false identification rate on target-absent (TA) lineups despite good performance on target-present (TP) lineups. One explanation is that children feel a social pressure to choose when presented with a TA lineup. We investigated whether experimenter familiarity would reduce social pressure and improve accuracy on TA lineups. Children (5-7 years, N  = 120) watched a short video of a staged theft; 1-2 days later they completed a TP or TA lineup with a familiar or unfamiliar experimenter...

This study examined the relationship between the actual level of physical violence in sexual offenses and dark triad, empathic and impulsive personality traits of their perpetrators. Sixty-four male perpetrators of sexual offenses without any serious mental illness were included. A 5-point Likert-type coding system based on Violence Profile for Current Offense was applied to assess the severity of physical violence of each sexual offense. Personality traits of dark triad (psychopathy, Machiavellianism, narcissism), trait empathy and impulsiveness were also evaluated...

Few studies have examined the prevalence of mental illness in young people over time within the same jurisdiction. In the current study, we compared data from three large surveys of youth in custody in New South Wales, conducted in 2003, 2009 and 2015. We examined rates of mental illness, self-harm and suicidal behaviours, substance use and childhood trauma and found little consistent change over time, though some fluctuations were observed regarding certain mental illnesses and substance use. We also descriptively compared findings with observed rates for the general population and found that young people in custody showed higher levels of all examined variables...
