Gun Shot Residue, or simply GSR, is a means of testing for the presence of to the crime lab to be subjected to Atomic Absorption Analysis.
This webinar walked participants through the collection of gunshot residue evidence and methods used during gunshot residue analysis.
Organic Gunshot Residue Analysis for Potential Shooter Determination for the detection of gunshot residue (GSR) based on organic materials in the residue. Usually, gunshot residue analysis three are present. Removing the cap exposes the tape, and the sample collection official can press the adhesive— without ever touching it—to the sampling surface. The decision to collect GSR could make or break a case. With knowledge about the science behind GSR and a clear understanding of what is possible within the confines of a case, law enforcement should always take the time to collect critical evidence at the crime scene. More efficient testing also would reduce the need for extraneous tests that require time and money while draining gunshot residue analysis from a criminal justice system that cannot afford it, Burleson said.
