How Messy is a Contact Shotgun Blast??? (Alex Murdaugh Trial)

Published on March 15, 2023
Duration: 8:51

This guide details the experimental setup and execution of simulating a contact shotgun blast, inspired by the Alex Murdaugh trial. It covers defining contact shots, setting up a realistic ballistic gel model, performing the shot with a Benelli Supernova, and analyzing the resulting forensic evidence. The demonstration highlights the significant pressure and gas effects unique to contact wounds, offering insights relevant to forensic analysis and trial testimony.

Quick Summary

A contact shotgun blast occurs when the muzzle is pressed against the target, causing damage from trapped gases and pressure. This differs from a standard blast where gases dissipate. Experiments using a Benelli Supernova and ballistic gel show significant destruction, including stippling and burns, providing insights relevant to forensic analysis.

Frequently Asked Questions

What is a contact shotgun blast?

A contact shotgun blast occurs when the firearm's muzzle is pressed directly against the target. The damage is exacerbated by intense pressure and gases trapped within the barrel that have nowhere to escape but into the target.

How does a contact shotgun blast differ from a standard blast?

Unlike a standard blast where gases dissipate quickly, a contact blast traps these gases and pressure, leading to more severe internal destruction and unique external effects like stippling and burns around the wound.

What firearm was used in the contact shotgun blast simulation?

The simulation utilized a Benelli Supernova 12-gauge pump-action shotgun, loaded with a 3-inch, 12-pellet 00 buckshot shell traveling at approximately 1300 feet per second.

What forensic evidence is observed after a contact shotgun blast?

Post-blast inspection reveals extensive fluid splatter, bone fragments, and debris. The firearm's barrel may also be coated in simulated tissue and fragments, with stippling and burns visible on the target area.
