Exploring gunshot residue detection in fingerprints by functionalized particle-coupled matrix-assisted laser desorption/ionization mass spectrometry.

In Analysis
In firearm forensic investigations, detecting gunshot residue (GSR) is crucial for linking firearms to suspects and determining firing distance for forensic reconstruction.

Identification of gunshot residue: a critical review

Forensic Science International, 2001
A review of the scientific papers published on inorganic gunshot residue (GSR) analysis permits to study how the particle analysis has shown its capability in detection and identification of gunshot residue. The scanning electron microscope can be the most powerful tool for forensic scientists to determine the proximity to a discharging firearm and/or ...

Gunshot Residue Deposition With and Without Firearm Suppressors (Silencers)

American Journal of Forensic Medicine and Pathology
Forensic pathologists recognize the importance of estimating the range of fire for gunshot entrance wounds. Classically described ranges of fire include contact, close range, medium (or intermediate) range, and indeterminate (or distant) range.

Detection of Gunshot Residue on Glass Fired using Airguns and Insas LMG 5.56mm

Indian Journal of Forensic Medicine and Pathology
Locating and retrieving gunshot residue from the scene of the crimeis important for the investigation of shooting-related crime incidents. The presence of gunshot residue on the glass that can be hit as anintermediate target is occasional but not ...

Gunshot residue collection using film-lift techniques

Forensic Science, 1974
Abstract A simple and efficient procedure developed for the collection of firearm discharge residues from human body surfaces for forensic analysis is presented. A unique formulation of reconstituted cellulose (called “Film-Lift”) when applied on surfaces forms a readily removable film which gathers and retains almost all of the fine particulates ...

Detection of gunshot residues in routine CTs

International Journal of Legal Medicine, 2000
The forensic assessment of non-fatal gunshot wounds often proves to be difficult as wounds have usually been cleaned and protected with a sterile bandage by the time of the examination. The aim of our investigation was to test the possible application of computed tomography (CT) for the forensic assessment. Doing so raised the questions whether gunshot

An Interesting Gunshot Residue Pattern

Journal of Forensic Sciences, 1985
Abstract The presence of lead, copper, and antimony (Sb, Cu, and Pb) was shown on the left back and right palm by use of anodic stripping voltammetry (ASV). These data are consistent with a cross overhand held weapon (left over right).

Elemental quantification of large gunshot residues

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2015
Abstract In the present work we embarked on the evaluation of the Sb/Pb, Ba/Pb and Sb/Ba elemental ratios found in relatively large particles (of the order of 50–150 μm across) ejected in the forward direction when a gun is fired. These particles are commonly referred to as gunshot residues (GSR).
