How does distance affect gunshot residue patterns?

Distance has a significant impact on gunshot residue patterns, primarily because the dispersion of residue is influenced by the proximity between the shooter and the target. As the distance increases, the concentration and spread of gunshot residue can vary—closer shots typically produce a more concentrated pattern of residue around the target area, while shots fired from further away may result in a more dispersed pattern.

This relationship can be crucial in forensic investigations, as it allows investigators to establish the most likely position of the shooter in relation to the victim at the time of the shooting. By analyzing the quantity and distribution of gunshot residue, forensic experts can draw conclusions about the shooter's location, which aids in reconstructing the events surrounding the incident. Understanding this aspect of gunshot residue patterns is essential for accurately interpreting evidence in crime scene investigations.
