Absolute dating of modern paper using 14C bomb peak data of the paper fibers

This study demonstrates a method for absolute dating of paper using the 14C bomb peak and combining AMS radiocarbon measurements of paper fiber mixtures with detailed qualitative and quantitative analysis of the fiber composition. Radiocarbon measurements were performed on fibers...

Forensic timeline investigation of Apple Health app on iOS

Apple Health data provide critical forensic insights into a user's physical activities, exercise routines, sleep patterns, and biometrics. However, the complexity of its database schema and frequent iOS updates pose significant challenges for automated forensic analysis. Thi...

Sharp force trauma analysis without animal bones: A proposal for sustainable and ethical...

Sharp force trauma has been the leading cause of homicide in England and Wales for more than a decade. Experimental research on sharp force trauma frequently relies on animal bone as a substitute for human remains, yet their ethical acceptability and comparability to human bone r...

Help v. harm: How a “lookup table” for evaluating DNA evidence given activity‐level...

DNA testing methods have become incredibly sensitive. Many court stakeholders have accordingly shifted their focus from questions about "who is the source of the DNA?" to "how did the DNA get to be where it was found?" Given this shift, some in the forensic DN...

GenoEye: A machine learning‐based framework for the prediction of intermediate eye color...

Forensic DNA phenotyping (FDP) enables the prediction of externally visible characteristics from genetic data, providing valuable investigative leads. While current approaches achieve high accuracy for blue and brown eye color, the prediction of intermediate phenotypes such as gr...

A novel relationship between time offsets in capillary electrophoresis and DNA sequence...

Next‐generation sequencing (NGS) provides increased discriminatory power in forensic DNA analysis due to the detection of isoalleles. Differences in sequences between alleles allow for a second layer of differentiation between DNA contributors beyond the number of short tandem re...

A 4‐zone model to determine fentanyl overdose probability

Determining the cause of death using postmortem fentanyl concentrations in femoral blood remains a major challenge in forensic toxicology. This is due to substantial concentration overlap between overdose deaths and incidental non‐drug‐related deaths. Existing literature largely ...

Determining the utility of radio frequency identification (RFID) technology for disaster...

Radio frequency identification (RFID) technology was evaluated as a method for electronically tracking human remains and associated identifying information during mass fatality incidents. Conventional tags are prone to physical damage and failure, which can compromise identificat...

Differentiating intentional ketamine use from unintentional exposure as an adulterant...

Recreational ketamine use and related adverse outcomes have been increasing; however, correct diagnostic classification of quantitative oral fluid test results remains challenging, considering the potential for unintentional exposure to ketamine as an adulterant in other drugs. W...

Stakeholders' perspectives on integrating point‐of‐care diagnostics into forensic death...

Unnatural and unexplained deaths present critical challenges to the criminal justice, medico‐legal, and public health systems. This study explored forensic professionals' perspectives on the integration of point‐of‐care (POC) diagnostics into unnatural death investigations i...
