Pyrotechnic Residues in Gunshot Residue Analysis

Proceedings, annual meeting, Electron Microscopy Society of America, 1985
Particle analysis by scanning electron microscopy with energy-dispersive x- ray analysis is one of the current methods used in crime laboratories to aid law enforcement in identifying individuals who have recently fired or handled a firearm. During the discharge of a firearm, the high pressure caused by the detonation of the cartridge materials forces ...

Close Proximity Gunshot Residues

Journal of Forensic Sciences, 1986
Abstract Intuitively, a hand held in close proximity to a firearm at the instant of discharge will intercept a significant amount of gunshot residue, even though the hand did not actually come into contact with the weapon. There is, however, little information specifically described in the forensic science literature concerning the ...

Formation of Gunshot Residues

Journal of Forensic Sciences, 1982
Abstract Scanning electron microscopy combined with energy dispersive X-ray analysis (SEM-EDX) was used to determine new structural criteria to further substantiate the view that gunshot residue (GSR) particles have a characteristic structure. Because GSR particles are formed by rapid cooling from extreme temperatures and high pressures,

Gunshot Residue, Ten Years Later

The American Journal of Forensic Medicine and Pathology, 1991
Gunshot residues may be central to a competent reconstruction of a shooting incident. When a young boy was shot in the neck by a playmate using a .22-caliber single-action revolver, permanent paralysis from mid-thorax downward ensued. Ten years later the victim sued the importer, the vendor, the German manufacturer, and the shooter's family ...

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

A Photoluminescence Technique for Detection of Gunshot Residue

Journal of Forensic Sciences, 1975
Abstract When a suspect has been apprehended following a shooting, detection of gunshot residue on his hands may provide significant evidence in the investigation. The determination of the firing distance (distance from weapon to target) by the distribution of gunshot residue around a bullet hole is also useful in various gunshot ...

Voltammetric analysis of luminescent markers in gunshot residues

Journal of Forensic Sciences, 2023
AbstractCurrently, SEM‐EDS is used to detect gunshot residue (GSR) from the presence of Ba, Pb, and Sb in the sample. However, the development of new nontoxic ammunition (NTA) has prevented conventional metals from being found. In this work, we aim to determine the presence of an inorganic luminescent chemical marker based on rare earth in gunshot ...

Gunshot Residue Analysis—A Review

Journal of Forensic Sciences, 1997
Abstract A review of all aspects of analysis associated with gunshot residues is provided. This includes a summary of what both inorganic and organic residues are, how they arise and how they may be collected from a variety of substrates.

Evaluation of a Photoluminescence Technique for the Detection of Gunshot Residue

Journal of Forensic Sciences, 1977
Abstract This is the second paper in a series describing the photoluminescence technique for detection of gunshot residue. It presents results of a substantial number of analyses of samples obtained for a variety of handguns and cartridges and collected under various conditions.

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).
