Answer:
Not possible
Step-by-step explanation:
Measuring the pattern of the particulates of the gunpowder residue gives an idea of how far the shot was from the gun shot and its target. At around 18-24 inches most firearms will start to deposit considerable concentrations of gunshot residues that may or may not be visible to the eye. At distances of less than around 12 inches heavy concentrations of visible gunshot residues will normally be deposited.
