Study Notes
Wound Ballistics
- Tissue damage is contributed by the forward motion of the bullet, temporary cavity formation, and the deposition of soot and propellant grains in the skin.
- Hollow point and soft nose bullets mushroom or deform on impact, causing larger wound cavities.
Bullet Impact
- The forward motion of a bullet indenting the skin and abrading the margin of the entry wound is called a "abrasion collar" or "marginal abrasion".
- The burning hot gases from the muzzle at close range can cause additional damage to the skin.
Bullet Composition
- Larger bullets cause larger wound cavities due to their increased size and kinetic energy.
- Unburned, partially burned, and burning propellant grains can abrade and embed in the skin, causing additional damage.
Document Examination
- A questioned document is a document whose authenticity or validity is disputed.
- The term "document" originates from the Latin word "documentum", meaning "lesson" or "teaching".
- A holograph document is a document written entirely in the handwriting of the signer.
- The responsibility of a document examiner is to investigate and provide expert opinion on the authenticity of disputed documents.
- The scientific process of investigating questioned documents is called Questioned Document Examination (QDE).
- A fraud investigator specializes in investigating fraudulent documents and identifying forgeries.
- The main difference between a document examiner and a paper and ink specialist is that a document examiner focuses on the handwriting, signatures, and other aspects of a document, while a paper and ink specialist focuses on the physical materials used in the document.
