Special Edition Crime Series - The JFK Assassination, Part 2

Published on November 23, 2021
Duration: 16:46

This video details the forensic firearms examination process used in the JFK assassination investigation. It explains how firearms examiners identify the specific rifle, ammunition, and cartridge cases used, and how they analyze bullets and fragments for microscopic characteristics. The content emphasizes the scientific nature of this evidence, which is not subject to interpretation, and discusses the analysis of gunpowder residue, bullet wipe, and scene reconstruction techniques.

Quick Summary

Forensic firearms examination scientifically identifies weapons by comparing microscopic 'individual characteristics' on bullets and cartridge cases to test-fired examples. This process, using comparison microscopes, reveals unique tool marks left by the firearm's barrel and breech face, allowing for definitive matches without relying on probability.

Frequently Asked Questions

How does forensic firearms examination identify a specific weapon?

Forensic firearms examination identifies a weapon by comparing microscopic 'individual characteristics' left on bullets and cartridge cases to those produced by test-firing the suspect firearm. These unique marks, like striations from the barrel or impressions from the breech face, are like a fingerprint for the firearm.

What is 'bullet wipe' and how is it used in investigations?

Bullet wipe is a black ring of residue, often containing lead and gunpowder particles, found on clothing or surfaces where a bullet has passed through. It's a crucial indicator of a bullet's entry hole and can help determine the trajectory and proximity of the shot.

What are the possible outcomes of a firearms identification analysis?

A firearms identification analysis can result in three distinct conclusions: an identification (meaning the evidence was fired from the suspect firearm), inconclusive (meaning there were some class characteristics but not enough individual characteristics for a definitive match), or negative (meaning the evidence was not fired from the suspect firearm).

How was the 6.5 Carcano rifle linked to Lee Harvey Oswald?

The 6.5 Carcano rifle was linked to Lee Harvey Oswald through a serial number trace that led to its purchase from Kline Sporting Goods via mail order. He used the alias 'A. Hiddel' for the purchase, and evidence like a photograph of him with the rifle and a palm print on its disassembled parts further solidified the connection.
