"Grab your gear",
barked Federal Agent, Leroy Jethro Gibbs, to his team, played by actor Mark
Harmon, from the CBS hit television show, NCIS,
"we have a dead marine". Any crime scene, whether it be a murder or a
robbery requires an investigation. The science used to help solve
crimes is called forensic science. The investigation is designed to
uncover evidence that can be used to identify the victim or the suspects perpetrating
the crime. The evidence can take on many forms, including: the murder weapon,
gun shells, gun residue, body fluids (DNA), and fingerprints, to name a few.
Fingerprints are one of the oldest and most common types of physical evidence found at a crime scene. Fingerprints are left behind almost every time something is touched. Since every person has a unique set of prints, they are a great tool for identification.
Some fingerprints are visible; you can see marks left on a surface by dirty or oily fingers. Dusting is usually used for this type. Other prints are latent; you can't see them, but there are marks left by sweat, amino acids, and other organic residue from fingers.
In recovering latent impressions there are numerous products available for the task. One of the conventional methods is called mechanical development. Mechanical development is the use of a brush and powder to physically dust the surface. This technique allows the particles of the powder to adhere to contaminates. The mechanical development is for nonporous items and surfaces.
Gordon Brush® manufactures three types of brushes for recovering latent impressions: (1) Fiberglass (super fine for soft brushing action); (2) Natural hair (Squirrel, Goat, horse hair); (3) Feather brush (are made with the finest Marabou feathers to easily dust powder or fine particles from the area of interest).
With over 17,000 different kinds of brushes for every industry imaginable, Gordon Brush's premium line of American made stock or custom brushes will do the job for which they are intended™. If a brush exists, we have it…if it doesn't, we'll make it!
