Calculating measurement uncertainty is a helpful exercise for identifying components or steps in a forensic analytical procedure that contribute to measurement variance. In this study, we used a bottom up approach to identify components in our procedures that contribute to measurement variance in our Department of Defense (DoD) Drug Demand Reduction Program (DDRP) Gas Chromatography Mass Spectroscopy (GCMS) analytical procedures for benzoylecgonine (BZE) and the THC metabolite, 11-nor-Δ9-THC-9-carboxylic acid (THCA) at 125% the DDRP concentration threshold (cutoff)...

The allelic frequency distributions and statistical forensic parameters of 26 mini short tandem repeat (mini-STR) loci in a sample of 1575 unrelated individuals from five different Brazilian regions were obtained. All the analyzed loci showed great diversity and were highly informative. The results were compared with those of the US Caucasian, African American, and Hispanic population studies. This study aimed to contribute to forensic analysis for human identification and inference of the evidential value in familial bond tests...

BACKGROUND: Developmental typologies regarding age of onset of violence and offending have not routinely taken account of the role of serious mental illness (SMI), and whether age of onset of offending in relation to onset of illness impacts on the manifestation of offending over the life course. AIMS: To test whether forensic psychiatric patients can be classified according to age of onset of SMI and offending, and, if so, whether subtypes differ by sex. METHODS: Details of all 511 patients enrolled into a large forensic mental health service in Ontario, Canada, in 2011 or 2012 were collected from records...

Throughout the United States, hundreds of thousands of sexual assault kits (SAKs) have not been submitted by the police for forensic DNA testing, which raises complex issues regarding how victims ought to be notified about what happened to their kits. In this project, we evaluated a victim-centered, trauma-informed victim notification protocol that was implemented in Detroit, Michigan. Most victims (84%) did not have a strong negative emotional reaction to notification, and most (57%) decided to reengage with the criminal justice system...

Estimating error rates for firearm evidence identification is a fundamental challenge in forensic science. This paper describes the recently developed congruent matching cells (CMC) method for image comparisons, its application to firearm evidence identification, and its usage and initial tests for error rate estimation. The CMC method divides compared topography images into correlation cells. Four identification parameters are defined for quantifying both the topography similarity of the correlated cell pairs and the pattern congruency of the registered cell locations...

Among pedophilic men, social contact with children has been discussed as creating a risk situation for sexual abuse. Also, pedophilic men searching for such contact are seen as harboring more beliefs legitimizing sexual contact with children. However, social contact may also decrease false beliefs. We tested these competing views in an anonymous Internet survey with a non-forensic, non-clinical sample of 104 self-classified pedophilic men. Results showed that both increased social and physical contact were significantly linked to fewer legitimizing beliefs toward sex with children, even when controlling for past psychotherapy, educational level, social desirability, and age...

Each forensic case is characterized by its own uniqueness. Deficient forensic cases require additional sources of human identifiers to assure the identity. We report on two different cases illustrating the role of teeth in answering challenging forensic questions. The first case involves identification of an adipocere male found in a car submersed in water for approximately 2 years. The second scenario, which involves paternity DNA testing of an exhumed body, was performed approximately 2.8 years post-mortem...

The research sought to develop and test a forensic database of surface soil variability within previously mapped geologic and soil units in southern California. This type of database could be used to link suspects to crime scenes or determine source locations of soil sample evidence. Variability was evaluated using (i) color, (ii) magnetic susceptibility, and (iii) particle-size distribution. Soil properties were analyzed for their ability to discriminate source areas using stepwise discriminant analysis. The percent correct predictions for geologic unit groups ranged from 30% to 100%...

An inflammatory response occurring after fatal traumatic brain injury (TBI) initiates time-dependent cascades of acute phase response. This may offer the potential to monitor postmortem biomarker levels of several pro-inflammatory cytokines to gain information about the cause of death and the trauma survival time. Cerebrospinal fluid (CSF) and serum samples were collected from forensic autopsies of 95 adult cadavers after postmortem intervals up to 6 days. The cases were divided according to their cause of death into fatal TBI (n = 46) with different survival times and age- and gender-matching non-TBI fatalities as controls (n = 49)...

X-chromosomal short tandem repeats (X-STRs) are used to complement autosomal and Y-STRs in complex kinship testing, and can be of potential value when determining trace female DNA in male background. We analyzed extracted and directly-amplified samples of 501 males from the United Arab Emirates and report the forensic statistical parameters of 12 X-STRs and haplotypes of the four previously defined linkage groups using the Investigator Argus X-12 QS kit. Combined PDM, PDF, MEC Desmarais Trio and MEC Desmarais Duo based on allele (and haplotype) frequencies were 0...

Introduction: In forensic toxicology, challenges exist with quantification analysis of cocaine and metabolites in postmortem samples following extensive decomposition. Alternative matrices, such as bone could prove useful when other specimens are not available. Detection and quantification of drugs in complex matrices require time-consuming extraction processes. The objective of this study was to develop a robust extraction and clean-up methodology to efficiently extract cocaine, and its metabolites, in bone and reach target limits of detection using multidimensional chromatography...

BACKGROUND: Prosthetic arm research predominantly focuses on "bionic" but not body-powered arms. However, any research orientation along user needs requires sufficiently precise workplace specifications and sufficiently hard testing. Forensic medicine is a demanding environment, also physically, also for non-disabled people, on several dimensions (e.g., distances, weights, size, temperature, time). METHODS: As unilateral below elbow amputee user, the first author is in a unique position to provide direct comparison of a "bionic" myoelectric iLimb Revolution (Touch Bionics) and a customized body-powered arm which contains a number of new developments initiated or developed by the user: (1) quick lock steel wrist unit; (2) cable mount modification; (3) cast shape modeled shoulder anchor; (4) suspension with a soft double layer liner (Ohio Willowwood) and tube gauze (Molnlycke) combination...

Complex trauma (CT; for example, childhood abuse) has been associated with significant behavioral health problems (i.e., mental health and substance use disorders) and symptoms that are consistent with complex posttraumatic stress disorder (C-PTSD). CT is prevalent in adult forensic populations, and particularly important for women as they tend to report more adverse consequences of exposure to traumatic stressors and are entering the criminal justice system at a heightened rate compared with men. However, no studies have empirically tested the relationship among CT, C-PTSD, and behavioral health problems with gender among incarcerated adults...

In this paper, we describe the development of a novel method to detect oral bacteria by combining direct polymerase chain reaction (direct PCR) with an immunochromatographic strip (ICS), enabling the identification of saliva in forensic samples. Direct PCR was first used to directly amplify specific oral bacterial sequences (from Streptococcus sanguinis and Streptococcus salivarius) from swab samples, circumventing the need for tedious sample preparation steps such as cell lysis and DNA extraction and purification...
