Long bone asymmetry and hemihypertrophy as a skeletal marker of child abuse

Diaphyseal overgrowth is a well‐documented complication of long bone fracture in orthopedic studies, but it is not a condition commonly mentioned in the forensic literature as a possible indicator of child abuse. Here we present an occurrence of humeral hypertrophy associated wit...

A survey of explosive traces in public places

Interpretation and evaluation of trace explosives evidence requires practitioner understanding of factors including transfer, persistence, and environmental prevalence. This study builds on previous work and studies the contemporary prevalence of organic high explosives and inorg...

Patterns of observer error in scoring macromorphoscopic traits for population affinity

Revising methodologies is essential to understand the limitations and biases inherent in certain methods, which is crucial for obtaining reliable results. Due to the subjective nature of non‐metric methods, variation in trait scoring and its impact on accurately classifying biolo...

DNA analysts' experiences with human factors: A quantitative and qualitative snapshot

DNA analysis can play a crucial role in rightful and wrongful convictions. However, forensic experts' methods may be influenced by human factors, including cognitive bias. Examiners' efforts to mitigate such bias can play a role in their courtroom testimony. There is li...

Testing the efficacy of surface swab sampling to determine postmortem submersion interval ...

Postmortem interval (PMI) estimation contributes valuable information in the medicolegal investigation of decomposed human remains, and estimating the postmortem submersion interval (PMSI) can specifically aid investigations involving victims discovered in aquatic environments. M...

From crime scene to laboratory: A case study of a comprehensive investigation into an IBX...

An explosion in an industrial filtering unit, resulting in a fatality, triggered a comprehensive forensic investigation. Sixteen pieces of evidentiary materials were collected from the scene of occurrence. The chemical residue at the explosion's origin was identified as 2‐Io...
