Gunshot residue investigations using TXRF

, 2011
Bei Schmauchspuren handelt es sich um Rückstände von Munition, die nach dem Abfeuern einer Waffe im Raum verteilt werden. Für die Polizei ist es im Rahmen von kriminaltechnischen Untersuchungen wesentlich, möglichst viel Information über die elementare ...

Road mortality mitigation for red wolves requires a landscape approach

Wildlife Biology, EarlyView.
In 1980, the red wolf Canis rufus was declared extinct in the wild. However, starting in 1987, a captive breeding program allowed for a reintroduction effort in and around Alligator River National Wildlife Refuge (Alligator River NWR), North Carolina, USA. In 2012 the wild red wolf population peaked at about 120 individuals.

Optimal excitation wavelength for raman spectroscopic analysis of organic gunshot residue evidence [PDF]

, 2020
Gunshot residue (GSR) is a type of trace evidence that can often be recovered at violent crime scenes. There are two major types of GSR, organic gunshot residue (OGSR), and inorganic gunshot residue (IGSR). Traditional forensic analysis of GSR focuses on

Indirect fractures in long bones resulting from gunshot trauma: Occurrence, characterization, and need for additional research

Journal of Forensic Sciences, EarlyView.
Abstract Indirect fractures from gunshot wounds can occur when a projectile impacts soft tissue without making direct contact with the bone. Existing biomechanical and clinical research suggests that indirect fractures result in lower levels of comminution, and that resultant fracture patterns can resemble those seen in blunt force trauma (e.g., wedge ...

Non-destructive imaging, nitrite detection, and blood removal from fabric: Exploring gunshot residue (GSR) pattern visualisation

Gunshot residue (GSR) analysis forms the basis for estimating muzzle-to-target distance in shooting reconstructions. This study presents an optimised approach using Quantofix nitrite sheets and an alternate light source to enhance GSR visualisation. Free-

A rapid method for detection of gunshot residue using microwave plasma torch-mass spectrometry [PDF]

, 2010
A microwave plasma torch-mass spectrometer (MPT-MS) method was developed to detect simultaneously three heavy metal components (lead, barium, antimony) of gunshot residues.

Study of gunshot residue by NAA and ESEM/EDX using several kinds of weapon and ammunition

Journal of Radiation Research and Applied Sciences, 2015
This work is realized in view to determine appropriate techniques for the revelation of mineral gun shoot residues. Picked up from the crime scene, these indicial traces are used as material proofs for helping and guiding judicial investigations.

Interaction of gunshot residues (GSR) with natural and synthetic textiles having different structural features

Talanta Open, 2020
This study relies on the ability of six different fabrics to retain gunshot residues on their surfaces, and their capability to let them pass through.

Suicides disguised as homicides through weapon concealment: A two‐way copycat phenomenon between fiction and real world

Journal of Forensic Sciences, EarlyView.
Abstract Suicides disguised as homicides present a persistent challenge in forensic case analysis, particularly when the weapon is deliberately removed after discharge. This study investigates the evolution of weapon concealment techniques—specifically the “load‐and‐rope” and “helium balloon‐tied gun” methods—across documented casework, forensic ...

Transfer and Persistence of Gunshot Residue Particles [PDF]

, 2010
In the U.S., although this technique has been in use for many years, there is still debate as to what constitutes GSR. When the firing pin strikes the primer, the priming compound is compressed and detonates since it is sensitive to percussion.
