Diagnosis of lethal cyanide poisoning. Analysis by Anion‐Exchange Chromatography with...
Cyanide is a poison widely used in cases of suicide or homicide. Although various methods to identify and quantify this substance are reported in the literature, they are mainly validated on biological fluids (e.g., blood and urine). In the present study, the Anion‐Exchange Liqui...
Postmortem THC in decedents following legalization of recreational cannabis in Clark...
Marijuana is the most prevalent illicit substance used globally. With increasing US legalizing recreational marijuana, more evidence is vital to minimize potential health risks. This study was conducted to test several hypotheses regarding postmortem THC/COOH‐THC in decedents bef...
Review of direct PCR and Rapid DNA approaches to streamline sexual assault kit testing
Crime laboratories have been faced with large casework backlogs due to lengthy processing times, limited resources and scientists, and rising crime rates. Evidence related to sexual assault crimes, specifically sexual assault kits (SAKs), heavily contribute to the reported backlo...
Portable Raman spectroscopy applied to the study of drugs of abuse
The use of drugs of abuse has grown significantly in recent decades. In forensic chemistry, methods of identifying and characterizing illicit drugs contribute to the interests of researchers, experts, and public security authorities. Among existing methods, portable Raman spectro...
Evaluation of tetrahydrocannabinolic acid (THCA) synthase polymorphisms for distinguishing...
The Controlled Substances Act (CSA) classifies marijuana (Cannabis sativa) as a Schedule I illicit drug. However, the recent Agriculture Improvement Act of 2018 (U.S. Farm Bill) removed hemp from the definition of marijuana in the CSA, making it a legal crop. As a result, many he...
Developmental validation of an efficient differential separation method incorporating the...
The differential separation method is key to recovering a DNA profile of the sperm donor from sexual assault samples. However, low numbers of spermatozoa from the perpetrator are often swamped by the victim's epithelial cells or lost during the separation process, with the s...
Quantitative analysis of smokeless powder particles in post‐blast debris via gas...
Forensic analysis of smokeless powder particles recovered from the debris of an improvised explosive device can provide information about the type of smokeless powder used and can aid investigation efforts. In this study, quantitative methods were used to yield information about ...
Smartphone‐based colorimetric determination of gamma‐butyrolactone and gamma...
Gamma‐hydroxybutyrate (GBH) is a popular recreational drug. Its strong sedative and amnesic effects have led to drug‐facilitated sexual assaults, poisonings, overdose, and death. As a result, legislation has restricted its availability leading to GHB, consumers switching to its p...
Microbial community succession of submerged bones in an aquatic habitat
After death, microbes (including bacteria and fungi) colonize carrion from a variety of sources during the decomposition process. The predictable succession of microbes could be useful for forensics, such as postmortem submersion interval estimation (PMSI) for aquatic deaths. How...
