Finding gunshot residue (GSR) indicates that an individual has likely been in close contact with a firearm or involved in a shooting situation. Gunshot residue comprises microscopic particles that are expelled when a gun is fired. These particles can land on the skin, clothing, or other surfaces near the shooter or the firearm itself.

If an individual has GSR on them, it suggests they either discharged a firearm, handled a firearm that was recently fired, or were in close proximity to a shooting event. This is significant in criminal investigations, as it can help establish a connection between the individual and the crime.

The other options presented do not align with the implications of GSR. For example, if an individual has GSR, it contradicts the idea that they have not handled a gun, that they are merely a witness, or that they are not connected to the crime scene. Therefore, the presence of GSR provides strong evidence of an individual’s potential involvement in a firearm-related incident.
