APPENDIX X
Appendix X compiles the expert firearms testimony presented to the Commission. The principal witnesses were Robert A. Frazier, Cortlandt Cunningham, and Joseph D. Nicol of the FBI Firearms Identification Section, with supporting references to firearms evidence technician Joseph A. Mooney and Eugene Boone. Frazier and Ronald Simmons of the U.S. Army Infantry Weapons Evaluation Branch also testified on rifle capability, a subject addressed earlier in the Report. The appendix cites Hatcher, Jury & Weller, “Firearms Identification, Investigation, and Evidence,” chapters 13-14, as the leading secondary reference. The cited testimony establishes the chain of custody and identification of the rifle (CE 139, 541), the recovery of the weapon on the sixth floor of the Texas School Book Depository, the matching of the rifle to cartridge cases and the bullet recovered from Governor Connally, the examination of the assassination weapon’s optics and condition, and the results of paraffin and nitrite tests. The appendix documents the FBI’s comparison of the rifle to test firings, the analysis of the cartridge case and bullet evidence (CE 139, 541), and the FBI’s reconstruction of the assassination weapon’s characteristics, and supports the Commission’s findings on rifle capability and bullet identification discussed at pages 188-194 of the Report.
CAPÍTULO VIII.
Chapter VIII presents the forensic and physical evidence examined during the investigation, covering firearms identification, ballistics, fingerprints, document and handwriting analysis, photographs, wound ballistics experiments, and related scientific examinations. The chapter draws on expert testimony, laboratory analyses, and documentary exhibits to systematically evaluate the physical evidence associated with the case.
Firearms Identification
The firearms identification section establishes the methodology and findings used to link firearms evidence in the investigation, drawing on expert testimony and weapons reference materials to evaluate the characteristics of the rifle involved.
Bullet and Fragment Examinations
The examination of bullets and fragments details the laboratory analysis of projectile evidence, including the comparison of recovered bullet fragments against test-fired ammunition, as documented through Commission exhibits and expert witnesses.
Cartridge Cases
The cartridge cases section addresses the analysis of spent cartridge cases, their markings, and the conclusions drawn from comparing them to the suspected firearm, supported by expert testimony and physical evidence exhibits.
Fingerprint Analysis
The fingerprint analysis section covers the examination of latent prints recovered from various pieces of evidence, including the rifle, with reference to established fingerprint identification practices and expert testimony from fingerprint examiners.
Examination of Rifle
The examination of the rifle section documents the physical inspection and testing of the recovered rifle, including its identification, condition, and characteristics as established through forensic analysis and witness testimony.
Document and Handwriting Analysis
The document and handwriting analysis section introduces the methodology and general approach used by questioned documents examiners, including reference to authoritative texts on the subject and the credentials of the expert witnesses involved.
Oswald’s Handwriting
The section on Oswald’s handwriting presents the comparative analysis of handwriting samples attributed to Oswald, including the examination of exemplars obtained during the investigation and the conclusions reached by handwriting experts regarding authorship of specific documents.
Photographs of Oswald
The photographs of Oswald section addresses photographic exhibits depicting the subject, their provenance, and their use as reference material in various forensic comparisons conducted during the investigation.
Photographic Evidence
The photographic evidence section provides an overview of the photographs collected and analyzed as part of the investigation, including their source, chain of custody, and significance to the case.
Wound Ballistics Experiments
The wound ballistics experiments section details the scientific testing conducted to evaluate bullet behavior, including experiments performed by medical and forensic experts to determine bullet trajectories, velocities, and effects on tissue and materials.
Bullet Fragments
The bullet fragments section presents the analysis of recovered metal fragments, their composition, and their relationship to the ammunition and weapons involved in the investigation.
Hair and Fiber Analysis
The hair and fiber analysis section covers the microscopic examination of hair and fiber evidence, including comparisons between trace evidence recovered from various items and known samples, as conducted by forensic experts.
