Gunshot Residue Patterns - Web gunshot residue ( gsr ), also known as cartridge discharge residue ( cdr ), gunfire residue ( gfr ), or firearm discharge residue ( fdr ), consists of all of the particles that are expelled from the muzzle of a gun following the discharge of a bullet. Evidence typically includes clothing and photographs of gunshot wounds. Web gunshot residue (gsr) is a shred of important trace evidence which helps forensic scientists solve a huge range of incidents related to firearms. It is most often arrayed as a pattern around a suspected bullet hole. Web the use of gunshot residues for determining the distance of the muzzle of a firearm from a target at the time of discharge is a subdiscipline of the forensic firearms specialty.
Evidence typically includes clothing and photographs of gunshot wounds. The clothing submitted to the laboratory will be examined to determine if a pattern of gunshot residue is present and there are a number of examinations conducted to aid in this. Web the use of gunshot residues for determining the distance of the muzzle of a firearm from a target at the time of discharge is a subdiscipline of the forensic firearms specialty. Web the pattern and density of gsr is varied due to the complexity of the firing process such as distance and type of firearms. Web this residue, called gunshot residue (gsr), can consist of both burned and unburned primer or powder components, combined with additional residue from the surface of the bullet, surface of the cartridge case, and lubricants used on the firearm. Web gunshot residue is normally a combination of gunpowder residues and lead residues. These residues are called primer residue, firearm discharge residues or gunshot residue (gsr).
