PRIMER RESIDUE TRACES

When a weapon is fired, gunpowder residues are propelled toward the target. Primer and gunpowder residues are also blown back in the direction of the shooter. In most cases, trace amounts of these residues are deposited on the shooter’s firing hand. The detection of these trace residues can give valuable information regarding whether or not a particular individual has recently fired a weapon. The collection of primer residues deposited on the hand of the shooter—normally on the thumb web and the back of the hand holding the weapon, is accomplished through sampling for SEM or AAA analysis. Determining whether or not a particular person has fired a weapon is normally accomplished by measuring the amount of barium and antimony on the suspect’s hands. Atomic absorption spectrophotometry analysis has proven to be very successful in identifying these trace residues.

Atomic absorption analysis

Atomic Absorption Analysis is considered to be a sensitive and most effective method for the detection of firearm discharge residue on the skin or clothing of a suspect. The AAA process has been accepted in federal and state courts as conclusive evidence In numerous cases. The AAA process detects the presence of barium, antimony, copper and lead. Barium and antimony are present in the primers of most United States-made and some European brands of ammunition, while copper and lead particles originate from cartridge cases and projectiles. Upon detonation of a cartridge, these elements are deposited on the shooter’s hands. The AAA100 kits are used to swab the entire surface of the suspect’s hands or clothing (see photos left). The samples taken are then submitted for laboratory analysis. Due to the extreme sensitivity of atomic absorption analysis, the swabs, preservation tubes, nitric acid solution and container must be free from contamination. The AAA100 kit contains 10 individual test kits and the components of each are handled under controlled conditions to ensure absolute minimum contamination.

GUNPOWDER PARTICLE DETECTION KIT

The distance of a firearm discharge is an important factor in crime scenes. The close range firing in a suicide, murder or Rother crime involving firearms can be determined by the detection of powder particles. A study of the scorching, blackening and powder patterns on the object or victim AT the crime scene can tell much about the distance and angle of firing. Dark rings around the bulle hole due to abrasion Or dirt can be confused with charring and blackening resulting from discharge. Small gunpowder particles, however, may go unnoticed if a sensitive method is not used. Therefore, a chemical test for the nitrite (burned) particles of gunpowder is very useful In a study of crime scenes involving firearm discharges—both on the victim and the criminal. The two-step reaction involved in the formation of orange dye is known as diazotization and coupling. It is this combination of reactions that is specific for nitrite ions. The No. GPD100 kit provides a sensitive and specific metod for the detection of nitrite particles at the crime scene. The sensitivity of the test eliminates the possibility of omission and error attending visual examination of the crime scene. By utilizing this kit, it is possibile to distinguish between close-range and distant firearm discharge. Closerange firing and approximate distances can be determined by the powder tattooing on the body or clothing of the victim. After the development of nitrite particles, test paper should be photographed for a permanent record of particle dispersion.

Seminal Fluid— The Acid Phosphatase Test

This test is considered to be the most conclusive, non-spermatozoa test for the presence of semen. The content of this enzyme is from 20 to 400 times greater in human semen than in any other fluid. This fact makes it unlikely that another material would test positive and give false results. The reagents for determining the presence of acid phosphatase in suspected stains are sealed in glass ampoules to ensure their integrity and long life. Preliminary examination before testing should be accomplished with longwave ultraviolet lights or an alternate light source such as BLUEMAXX™. The reagents should not be applied directly to suspected stains, Hus eliminating possible contamination in subsequent laboratory tests of the recovered evidence. The “contact” method, i.e., wetted filter paper is touched to the suspect area and the reagent is then applied to the contact paper only.
