Collecting touch DNA from glass surfaces using different sampling solutions and volumes:...
Touch DNA has become increasingly important evidence in todays' forensic casework. However, due to its invisible nature and typically minute amounts of DNA, the collection of biological material from touched objects remains a particular challenge that underscores the importa...
Fatal intoxication with 1,4‐butanediol: Case report and comprehensive review of the...
A fatal case of 1,4‐butanediol (1,4‐BD) oral ingestion is reported here, in which a 51‐year‐old man was found dead in his bed. According to the police report, the deceased was a known drug user. A glass bottle labeled (and later confirmed to be) "Butandiol 1,4" (1,4‐BD)...
Development of etching paste for serial number restoration on aluminum engine block
Engine numbers, which involve information regarding the engine type, production number, and year and place of manufacture, are used for identification purposes. Comprising of unique alphanumeric characters, the engine numbers are fully or partially obliterated especially in auto ...
Fatal intoxication involving 2‐methyl AP‐237
Novel synthetic opioids contribute considerably to the opioid epidemic, especially with the frequent emergence of structurally similar compounds. This case report describes a fatal intoxication involving 2‐methyl AP‐237. A 54‐year‐old Caucasian male was found deceased from an app...
Delayed elimination in humans after ingestion of colchicine: Two fatal cases of colchicine...
Colchicine has been widely used in the treatment of acute gout over the years, but it has a narrow therapeutic index, and overdose can be life threatening. A method using ultra‐high‐performance liquid chromatography–tandem mass spectrometry system was applied in two fatal cases o...
Geoforensic search to crime scene: Remote sensing, geophysics, and dogs
In the absence of surface indications of burial sites, law enforcement or humanitarian organizations are faced with the difficult task of focusing large‐scale ground searches to a manageable excavation area. A geoforensic‐based survey may exclude parts of the landscape for reason...
Use of a commercially available hydrogel as a novel DNA surface sampling tool
A common requirement in the military, law enforcement, and forensic mission space is the need to collect trace samples from surfaces using a method that not only readily captures the sample but also retains its integrity for downstream identification and characterization. Additio...
Understanding research methods, limitations, and applications of drug data collected by...
The National Forensic Laboratory Information System (NFLIS) is a drug surveillance program of the US Drug Enforcement Administration that systematically collects data on drugs that are seized by law enforcement and submitted to and analyzed by the Nation's forensic laborator...
Occupational exposure to traumatic evidence and posttraumatic stress symptoms in forensic...
Forensic science professionals are routinely exposed to potentially traumatizing evidence. This study aimed to estimate the prevalence of occupational posttraumatic stress disorder (PTSD) among forensic science professionals, identify job‐related correlates of PTSD symptoms, and ...
Review of analytical methods for screening and quantification of fentanyl analogs and...
Fentanyl, fentanyl analogs, and other novel synthetic opioids (NSO), including nitazene analogs, prevail in forensic toxicology casework. Analytical methods for identifying these drugs in biological specimens need to be robust, sensitive, and specific. Isomers, new analogs, and s...
Evaluation and classification of fentanyl‐related compounds using EC‐SERS and machine...
Multiple analytical techniques for the screening of fentanyl‐related compounds exist. High discriminatory methods such as GC–MS and LC–MS are expensive, time‐consuming, and less amenable to onsite analysis. Raman spectroscopy provides a rapid, inexpensive alternative. Raman varia...
NIST Mass Spectrometry Data Center standard reference libraries and software tools:...
The standard reference libraries and associated custom software provided by the National Institute of Standards and Technology's Mass Spectrometry Data Center (NIST MSDC) are described with a focus on assisting the seized drug analyst with the identification of fentanyl‐rela...
Organic impurity profiling of fentanyl samples associated with recent clandestine...
Nearly a decade ago, fentanyl reappeared in the United States illicit drug market. In the years since, overdose deaths have continued to rise as well as the amount of fentanyl seized by law enforcement agencies. Research surrounding fentanyl production has been beneficial to regu...
Rapid enantiomeric analysis of zopiclone in serum by supercritical fluid chromatography...
Zopiclone (ZOP) is a hypnotic drug prescribed to treat insomnia. Due to the chiral nature of ZOP, the psychologically active S‐form and inactive R‐form need to be determined enantiomerically in a forensic drug analysis. In the present study, a supercritical fluid chromatography (...
The detection of clandestine graves in an arid environment using thermal imaging deployed...
The Middle East is one of the world regions that has frequently suffered from armed conflicts that resulted in mass burials. However, the detection of clandestine graves in such an arid environment by deploying remote sensing payload on unmanned aerial vehicles (UAVs) has receive...
Emergence of fentanyl‐related deaths in Travis County, Texas and surrounding areas: A...
The opioid epidemic has affected the United States (US) for decades with fentanyl and its analogs accounting for a recent surge in morbidity and mortality. Currently, there is a relative lack of information characterizing fentanyl‐related fatalities specifically in the Southern U...
Prototypicality analysis of the Comprehensive Assessment of Psychopathic Personality (CAPP...
The Comprehensive Assessment of Psychopathic Personality (CAPP) model is a new lexically based concept of psychopathy that has potential clinical utility. The main purpose of this research is to investigate the generalizability of the CAPP conceptual model in South Korea. In the ...
Copycatting the smell of death: Deciphering the role of cadaveric scent components used by...
Human remains detection dogs (HRDD) are commonly used by law enforcement agencies to search for cadavers. Biological material is typically used as a training stimulus, also called aids, to train dogs to recognize the smell of cadavers. While HRDD training approaches have received...
