Novel Distance Estimation Method for Shotgun Discharges at Close Range

The learning objective for this presentation is to consider a new method for estimating shotgun-related shooting distances at close range, typically <1 m.

The research proposition was that close firing distances can be estimated from measuring the size of the shot-defect created upon a clothed human simulation.

This research has demonstrated the potential for a simple, cheap and non-destructive new method to estimate shooting distance at close range (<1m) through the application of traditional photography, and analysis using open source software (Fiji/ImageJ). This method still requires further testing, but has the potential for application in estimating firing distance when shot have not sufficiently spread and/or to further corroborate gunshot residue patterns observed through visual or chemical analysis.
