Chemical identification and optimization of the 4‐aminophenol colorimetric test for the...
The 4‐ Aminophenol (4‐AP) colorimetric test is a fast, easy‐to‐use, and cost‐effective presumptive assay of cannabis plant material producing different chromophores with THC‐rich cannabis (blue color) and with CBD‐rich cannabis (pink color). The main drawback of the 4‐AP test is ...
Persistence of cellular material after exposure to water
Disposing of items of forensic relevance in bodies of water is one countermeasure offenders can use to avoid detection. The impact of immersion in water has been explored for blood, saliva, and semen; however, few studies have assessed touch DNA. Here we report on the effect of e...

Compounds identified in an illicit generic Xanax tablet are the result of a failed...
Unintended compounds produced by inexperienced clandestine chemists may present a challenge in laboratories tasked with their identification. In March 2020, an anonymously submitted tablet purchased as a generic form of Xanax was analyzed by Erowid's DrugsData.org. The gas c...
Quantitative PCR overestimation of DNA in samples contaminated with tin
Metals can pose challenges while conducting forensic DNA analysis. The presence of metal ions in evidence‐related DNA extracts can degrade DNA or inhibit PCR as applied to DNA quantification (real‐time PCR or qPCR) and/or STR amplification, leading to low success in STR profiling...

Identifying reliable ions for the statistical differentiation of structurally similar...
Definitive identification of fentanyl analogs based on mass spectral comparison is challenging given the high degree of structural and, hence, spectral similarity. To address this, a statistical method was previously developed in which two electron‐ionization (EI) mass spectra ar...
An interlaboratory study to evaluate the utility of gas chromatography‐mass spectrometry...
Synthetic opioids such as fentanyl account for over 71,000 of the approximately 107,000 overdose deaths reported in the United States in 2021. Fentanyl remains the fourth most identified drug by state and local forensic laboratories, and the second most identified drug by federal...
