Vacuum Metal Deposition. Process of selective condensation of
metals under vacuum conditions; used to visualize friction ridge
detail.

A number of metals when deposited by VACUUM METAL DEPOSITION will delineate
fingerprints on some surfaces. Some of these work as single metal treatment
while others must be used in combination. The currently recommended combination
is GOLD followed by ZINC.
Lead, zinc, silver, gold, magnesium and a few other metals develop fingerprints
when deposited as single metals. Some of the known metal combinations are gold,
silver or copper followed by cadmium or zinc.

Vacuum Cyanoacrylate Ester
Fuming method, conducted under vacuum conditions, in which
cyanoacrylate polymerizes on friction ridge residue; used to

Validate
To make valid by checking the accuracy of a system.
Validation Study
A study to assess the limitations and benefits of a process or technique in order to
determine its usefulness. An adequate validation study should include the process,
comparisons to other similar processes, review of literature, limitations and values
of the process, and documentation of the testing that validates the conclusion.
Value
The value of a friction ridge impression is determined by the context in which the term is
used. An impression can have identification value, exclusionary value, value for
determining how an object was touch, value in determining if impressions were left
simultaneously, investigation value, analytical value, or probative value. An impression
can be of value in determining how an object was held but not have sufficient value in
determining identity. Additionally, an impression can have identification value but not
probative value.

Verification
“Verification is a form of peer review and is part of most sciences. Many
organizations erroneously use verification as a method of protecting against
errors in place of adequate training. While verification may prevent the
occasional error, its purpose is to verify process and objectivity as opposed
to only check results. It is also an excellent vehicle for training.”
David Ashbaugh, Detail 28 http://www.clpex.com
Verification insures objectivity and unbiased results, it does not insure
accurate results or conclusions.
Proof; confirmation of a process.

Confirmation of an examiner's conclusion by another qualified examiner.

surrounding ridge formations.

Virgin Islands v. Austin Jacobs (2001)
A burglary case that failed a Daubert challenge. The judge decided to exclude
the fingerprint testimony because the prosecutor hadn’t provided information
to the defense to determine if the fingerprint evidence was scientifically reliable.
The defense asked for the CV of the examiner (Maureen Richardson) and for an
explanation of the methodology to determine if a basis and reason existed for
the findings. The prosecutor failed to provide these items.
Visible Light
Visible light is a series of electromagnetic wavelengths that we can see. These
wavelengths range in frequency from 400-700nm and are seen as different colors.
The combination of all the colors in the visible light spectrum is referred to
as white light.
Volar
Related to the palmar and plantar surfaces.

Vollmer, August (1876-Nov. 4, 1955)
A Chief of Police in Los Angeles, California who started the first crime
laboratory in the United States. Vollmer, along with Paul Kirk, also
established criminology and criminalistics as an academic discipline. In
1950 the University of California Berkeley began offering criminal justice
degrees.
Vollmer’s obituary appears in the January 1956 issue of Fingerprint and
Identification Magazine.
Vucetich, Juan (AKA Vucetic, Ivan and Vucetic, Josip and Vucetic, Ivo) (1858-1925)
Working in Argentina, Vucetich is credited with deriving the classification
system used in South America. His classification system was originally
called 'The Icnofalangometric(ia) system' but after some modifications the
name was changed to 'Dactiloscopy' or 'Dactiloscopia', at the suggestion of
another fingerprint pioneer- Dr. Francisco Latzina,. Vucetich is also
credited as being the first person to use a latent fingerprint to solve a
crime. The real person who collected the evidence and made the identification
was Inspector Eduardo Alvarez, in 1892, but historically Vucetich is given the
credit because it is felt that Alvarez would have never done this without the
influence of Vucetich. Confronted with the fingerprint evidence, Francesca
Rojas confessed to murdering her two sons.
