A tale of two PG systems: A comparison of the two most widely used continuous...
The development of probabilistic genotyping (PG) systems to quantitatively analyze DNA mixture samples has been transformative in forensic science. TrueAllele® Casework (TA) and STRmix™ (STRmix) are the two most widely used PG systems in the United States. The two systems were ch...
Assessment of urine drug screen utility at autopsy to predict laboratory postmortem blood...
When faced with increasing drug‐related deaths and decline in practicing forensic pathologists, the need to quickly identify toxicology‐related deaths is evident in order to appropriately triage cases and expedite turnaround times. Lateral flow immunoassays conducted pre‐autopsy ...
Half‐volume validation of the NGM Detect™ PCR Amplification Kit and its application on...
The NGM Detect™ PCR Amplification Kit was designed particularly for genotyping degraded casework samples. This study aimed to validate the half‐volume amplification of the kit and to present its successful long‐term application. The validation was performed in accordance to the c...

A review of the contributions of forensic archaeology and anthropology to the process of...
Forensic archaeology and anthropology have developed significantly over past decades and now provide considerable assistance to the investigation process of disaster victim recovery and identification. In what are often chaotic death and crime scenes, the formal process of utiliz...
Study on the methods of visualizing bloodstains after thermal exposure
To establish the correlation between thermal conditions imposed on bloodstains and visualizing effect of enhancement techniques, infrared photography and four chemical enhancement reagents were used to visualize bloodstains following thermal exposure. A black tile was selected as...
Could synovial fluid be a useful substrate for the forensic analysis of diatoms?
To date, synovial fluid has not been the subject of targeted analysis as a possible substrate to search for the presence of diatoms in the forensic context of drowning. However, its unique characteristics of production and isolation from the external environment could make it sui...
Dissociation and the insanity defense: A review of U.S. Federal appellate case law
Pathological dissociation is relatively common in the United States and may be associated with violent or criminal behavior. Dissociative Disorders, especially Dissociative Identity Disorder, are considered controversial diagnoses by some in the psychiatric and legal professions....

Prevalence of gunshot residue particles on back seats of police vehicles
The presence of gunshot residue (GSR) in a sample can provide valuable information in forensic investigations by associating a suspect with a shooting incident. However, in order to have confidence in the integrity of the results' interpretation, the possibility of contamina...
Disaster victim identification: Stable isotope analysis and the identification of unknown...
Within the complex world of disaster victim identification, or DVI, forensic science practitioners use a variety of investigative techniques to work toward a common goal: identification of the decedents, bringing closure to the affected communities. Identification is a complex un...
Rare case of multiple self‐inflicted gunshot wounds to the chest in Poland
Multiple gunshot suicides are relatively rare and present significant challenges for investigators and forensic pathologists. In such cases, assessing the possibility of more than one shot being fired can be crucial in distinguishing homicide from suicide. We present a rare case ...
Seized drug reporting of NPS helps to guide regional toxicological practice: A 17 month...
Novel psychoactive substances (NPS) are everchanging and plague forensic laboratories who must identify an unending variety of emerging substances and evolve current methodologies to detect these substances. Identifying potential regional NPS targets and timely examining trends i...
Extending the discussion on inconsistency in forensic decisions and results
The subject of inter‐ and intra‐laboratory inconsistency was recently raised in a commentary by Itiel Dror. We re‐visit an inter‐laboratory trial, with which some of the authors of this current discussion were associated, to diagnose the causes of any differences in the likelihoo...
