Selective postmortem arterial angiography of head and neck using digital x‐ray or computed...
Identification of vascular injuries is crucial for complete postmortem evaluation and understanding of trauma deaths by the Medical Examiner. Some vascular injuries are difficult to evaluate due to challenging anatomic locations, especially in the head and neck. Documenting injur...
Analysis of automotive paint layers on plastic substrates using chemical imaging μ‐FTIR...
Automobile paint chips are a crucial piece of trace evidence for forensic investigators. This is because automotive paints are composed of multiple layers, including the primer, basecoat, and clearcoat, each of which has its own chemical composition that can vary by vehicle make,...

DNA typing of cyanoacrylate fumed latent fingerprints using GlobalFiler™ and ForenSeq™...
DNA typing of latent fingerprints is highly desirable to increase chances of individualization. We recovered DNA from Cyanoacrylate (CA) fumed fingerprints and used both GlobalFiler™ and ForenSeq™ DNA Signature Prep kits for DNA typing. For GlobalFiler™, samples were processed us...
Development and validation of a quantitative method for the analysis of delta‐9...
A quantitative gas chromatography mass spectrometry (GC/MS) method was developed for delta‐9‐tetrahydrocannabinol (delta‐9‐THC), delta‐8‐tetrahydrocannabinol (delta‐8‐THC), tetrahydrocannabinolic acid (THCA), and cannabidiol (CBD) in matrices including plant material, liquids and...
Modification of a liquid chromatography‐tandem mass spectrometry (LC‐MS/MS) method...
A variety of LSD analogs have emerged in recent years with dual purposes of avoiding prosecution from possession while providing new options for those willing to experiment with hallucinogenic drugs. In this study, a previously published automated sample preparation method for LS...

The effects of cognitive bias, examiner expertise, and stimulus material on forensic...
Forensic examiners have come under scrutiny due to high‐profile exonerations, highlighting the consequences that contextual bias can have on investigations. Researchers have proposed solutions to reduce the effects of bias including blind testing and redacting task‐irrelevant inf...
A detailed study on human height estimation model that combines video surveillance systems...
The increase of video surveillance systems has highlighted the interest in forensic anthropometric analysis of subjects who commit crimes and are captured by cameras during their criminal activities. There are different methodologies for human height estimation. Forensic research...

Eligible offender samples are missing in CODIS: A statewide approach to performing a...
In 2019, the Texas Department of Public Safety (TXDPS) Texas Ranger Division (TRD) identified approximately 3300 registered sex offenders (RSOs) from whom a "lawfully owed" DNA sample was missing from the Federal Bureau of Investigation's Combined DNA Index System ...
Massive gastropathy due to gallstone obstruction of the duodenum (Bourveret syndrome)
Gallstones are common in the general population and are often asymptomatic, but they can also cause complications such as cholecystitis and pancreatitis. In rare instances, they can lead to the formation of a cholecystoduodenal fistula and gallstone ileus. Gastric dilatation and ...

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...
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...
