Annotation

This article provides a response to statements made in a previously published article that discussed the complex nature of gunshot residue transfer and persistence, and how those complexities pose challenges for use as forensic evidence.

Abstract

This resource is a response to commentary received concerning "Transfer and persistence studies of inorganic and organic gunshot residues using synthetic skin membranes" published in Forensic Chemistry (2023) Volume 34, Article ID 100498 (see NCJ 307121). The original article presented the complex nature of gunshot residue (GSR) transfer and persistence introduces challenges and skepticism in its evidential value. The study evaluated the behavior and movement of inorganic and organic gunshot residues to assist in the evidence interpretation.
