Why is distance from the shooter important in crime scene investigations?

Distance from the shooter is crucial in crime scene investigations because it significantly influences the wound characteristics and patterns observed on the victim. The range at which a firearm is discharged affects several factors, including the type of injury sustained, the presence of gunshot residue, and the amount of tissue damage. For instance, close-range shots may result in distinct stippling or tattooing on the skin due to unburned powder particles that do not disperse over long distances, while shots taken from a distance might present different wound patterns, such as cleaner, more defined edges. Understanding the distance can also help investigators reconstruct the scene and establish how and why the incident unfolded as it did. This information is vital in piecing together the events leading to the shooting, thereby providing insights for both the investigation and potential legal proceedings.
