part 2 Flashcards
science of FA identification by means of the ammunition fired through them.
Forensic Ballistics
refers to the work of an investigator in the field.
Field investigation
refers to the examination/comparison conducted by Firearm examiner.
Technical Examination
C. the presentation of the “Ballistics Report” on firearms, bullet, shells and allied exhibits in court.
Legal proceedings
receives and conducts the laboratory examination at the laboratory and transmit the result of such examination to the requesting party.
Firearm Examiner
focused with the study of shots/pellets from smoothbore firearms like shotguns and muskets.
Shot Ballistics
discharge single but usually multiple shots/pellets in single fire.
Shotguns
is another smoothbore firearm that discharges single ball in one firing.
Musket
can be found at a distance of 5-8 yards .
These wads are very important in the identification of:
1.Gauge of weapon
2.Make of ammunition
Shot wads
1.wound is about 1.5 - 2 inches in diameter. Scorching, tattoing, singering maybe observed.
1-3 feet
shot begins to spread out.
Beyond 3 feet
wound will appear as a central hole with small perforations around.
4 feet
shots continue to spread out and produces a mass of small perforations with no central wound.
Beyond 4 feet
Measure the diameter of the wound (in inches) including the outermost perforations and then subtract 1 to arrive at the range of yards. 10 inches diameter, the range is 9 yards. (Note: 1m=1.09 Yards)
Approximation of Range
with the use of shotgun appear externally with a circular defect approximating the bore of the weapon used.
Contact wounds
