FBI / Lockheed-Martin 50k x 50k Study (1999)
A statistical study done to support the uniqueness theory of fingerprints. This study was used in
Daubert hearings to justify biological uniqueness and to validate fingerprint methodology. The
50k x 50k study was never published and therefore many claim that it is not a scientifically sound
study and should not be used as supporting evidence.

Fabricated Latent Print
A fabricated or falsified latent print is a latent print intentionally manufactured by law enforcement
personnel in order to enhance the case against a suspect. This can be done by intentionally
mislabeling a print (latent or inked) as coming from an object at the crime scene.

Aka Falsified Latent Print.

Fred van der Vyver (South Africa)
In March 2005 Fred van der Vyver was the main suspect in the murder of his girlfriend,
Inge Lotz. Crucial evidence against him was a fingerprint identification labeled as being
lifted from a DVD cover. The identification of the print was never in question. The
question was whether or not the fingerprint was actually lifted from the DVD cover or from
some other substrate. Fred van der Vyver maintained his innocence and provided an air
tight alibi while the State denied any possibility of a mistake. The first person to suggest
that the fingerprints were from a different surface was Mr. Nico Kotze. Several other
fingerprint experts, including Dr. David Klatzow, Mike Grace, Daan Bekker, Pat Wertheim
and Arie Zeelenberg, reviewed the case. Daan Bekker was the first person to state that
the latent print was lifted from a drinking glass. In December 2006, due to the experts’
findings, the South African Police Department announced that they were not going to
pursue the fingerprint evidence. When the trail began, the fingerprint evidence was
admitted as part of the evidence (along with other evidence that was suspected of being
fabricated). Mike Grimm, Bill Bodziak and Paul Ryder were the footwear experts in this
case. On Nov. 29, 2007 the judge, accepting that the latent print evidence did not come
from a DVD cover, found Fred van der Vyver not guilty of the charges against him. One
article about this case claimed that the judge also slammed the testimony of several
police witnesses who had given evidence on key forensic evidence, calling their evidence
“untrustworthy”, “unreliable” and “dishonest”.

Diana Boyd Monahan (Texas)
Indicted in 2000 on 13 counts of falsifying fingerprint reports on evidence she never
tested. She pled guilty and received 5 years probation.

New York State Police
In 1992 an investigator with the New York State Police, David L. Harding, was arrested
for fabricating evidence in a murder trial. Subsequently, 4 other employees (Robert M.
Lishansky, Craig D. Harvey, David M. Beers, and Patrick O’Hara) were charged with
fabricating fingerprint evidence in other cases. The total number of cases is estimated to
be as high as 40 cases.
In 1993, Shirley Kinge, one of the victims of fingerprint fabrication, sued the New York
State Police. In Feb. 2008, Judge Midey Jr. found that Kinge was the victim of malicious
prosecution and negligent supervision of the investigator who planted the phony evidence
implicating her in the crime. Senior Investigator David McElligott, the supervisor of the
Troopers involved, was forced to retire due to this scandal.

Deputy Sheriff Jesus Durazo
In 1992, the Arizona crime lab found that Jesus Durazo had fabricated fingerprint
evidence against a drug suspect. Despite his claims of innocence, when he was offered
to resign and no prosecution would occur, Durazo accepted.

James Bakken, Buena Park, California
In a 1967 bank robbery (some sources say 1969), James Bakken from Buena Park,
California fabricated evidence that resulted in William DePalma being found guilty and
sentenced to 15 years. DePalma began serving his sentence in 1971. Bakken testified
that the latent print was found at the bank but it was really an exact replica of a print from
a previous arrest. After Orange County investigated the claims, DePalma was released
after serving 3 years in prison. Bakken served 1 year on an unrelated charge. He could
not be prosecuted for the DePalma case because the statute of limitations had expired.

Det. Herman Wiggins, San Diego Police Department
In the 1970’s, Det. Herman Wiggins was found to have fabricated latent print evidence in
up to 40 cases. It is believed he had people touch the hood of his car and then he would
lift the prints and saved them for other cases. Officer Wiggins was arrested and faced
several counts of falsifying evidence. When the authenticity of the latent lift cards were
questioned, Officer Wiggins claimed that he had several lift cards together and they may
have gotten mixed up when he dropped his briefcase. In Dec. of 1974 he was found
guilty and sentenced to two years in custody.

Capt. James Barker
James Barker was one of the primary investigators in the 1943 Sir Harry Oakes Case.
Maurice O’Neill filed charges with the IAI against Barker for fabricating evidence in this
case. In a very unpopular decision, the IAI cleared Barker of any wrongdoing.

Fake Fingerprints
False friction ridge skin make by a person to evade identification or elude detection.

Falsifiable
There must be a way to prove the theory wrong. If we can’t prove it wrong, it is not a scientific
theory. This idea of a theory being falsifiable is one of the most important aspects of science. The
theory, “Beyond Earth there is intelligent life in the universe”, may be true, but it is not a scientific
theory since there is no way to prove it false.
http://home.earthlink.net/~johnh55/science/whatisscience.html 02-27-03
An attempt to falsify a conclusion is performed by making a concerted effort to seeking out
disagreement instead of seeking out agreement, support or confirmation. If the most critical
people agree with the conclusion then it is likely that the conclusion will hold up to strong scrutiny
of others and general consensus agreement will be achieved.

Falsified Latent Print
A falsified or fabricated latent print is a latent print intentionally manufactured by law enforcement
personnel in order to enhance the case against a suspect. This can be done by intentionally
mislabeling a print (latent or inked) as coming from an object at the crime scene.

Aka Fabricated Latent Print.

Faulds, Dr. Henry (June 1, 1843-Mar. 24, 1930)
Dr. Henry Faulds was a Scottish physician and a medical missionary in Japan. Dr. Faulds is
credited with doing many experiments to prove permanence and uniqueness. The earliest article
on using fingerprints as a means of identification was written by Faulds. Nature Magazine
published this article, “On the Skin-Furrows of the Hand”, on Oct. 28, 1880. Herschel replied in
Nature Magazine on Nov. 25, 1880 stating he had been using fingerprints as a means of
identification for over 20 years. Faulds is credited for being the first European to suggest that
fingerprints could assist in criminal investigations. In 2012, writings were found that suggest that
Robert Blake Overton recommended this much earlier than Faulds. Additionally, he is noted as
being the first person to use a latent fingerprint to eliminate someone as a suspect and he was
the person who recommended using printer’s ink to record fingerprints. In 1905 (as stated in “A
Manual of Practical Dactylography” page 60), Dr. Faulds published “Guide to Finger- Print
Identification”. In 1912 he published “Dactylography, The Study of Finger-Prints” (noted in “A
Manual of Practical Dactylography” page 10) and in approx. 1915 he published “A Manual of
Practical Dactylography”. Although Dr. Faulds greatly contributed to the science of fingerprint
identification, he was never given full credit for this during his lifetime.

Fault Line
Shadowing in an impression in the form of a curved line. A fault line is a visual clue that some
sort of distortion may exist.

Faurot, Joseph A. (Oct. 14, 1872-Nov. 20 1942)
In 1906, N.Y.P.D. Police Commissioner McAdoo sent Det. Sgt. Joseph Faurot to London to
obtain information of the process of fingerprinting, where it had been in use for several years.
Det. Sgt. Faurot returned with samples of the first fingerprint cards, at which time the Department
began to implement this new crime fighting technique. In 1908, a murder case was the first case
solved by the N.Y.P.D. utilizing this technology.
http://www.nycpolicemuseum.org/html/faq.html#fingerprint
Joseph A. Faurot retired from the New York Police Department as a Deputy Police Commissioner
in 1926.
http://www.findagrave.com/cgi-bin/famousSearch.cgi?mode=county&FScountyid=2013 10-08-
2004
Faurot was involved in many historical trials. One of the most well known trials was the case of
Caesar Cella in People v Crispi 1911. Remarkably, Retired Deputy Police Commissioner Joseph
Faurot was also involved in the trial that involved the first erroneous identification. In the 1926
Hall-Mills double murder trial (New Jersey), Joseph Faurot along with Lieutenant Fred Drewen
and Edward H. Schwartz erroneously identified a latent print on key evidence to one of the
suspects, William Stevens. J.H. Taylor and Gerhardt Kuhne (brother of Frederick Kuhne) testified
for the defense in this trial. William Stevens and the other suspects were acquitted. The double
murder, which actually happened in 1922, was never solved.

Features
As of November 2004 the National Fingerprint Board of England and Wales determined:

1. The Third Level Detail Working Group acknowledges that within the international
fingerprint community, the terminologies 1st, 2nd and 3rd Level detail is used. This group
recommends that because of the holistic nature of fingerprint identification, there is no
need for the use of these terms within the comparison process. ALL information assisting
with establishing the identification of an area of friction ridge detail will be termed,
‘features’.
2. ALL visible features employed within the identification process may be used without
regard to the information falling within any particular category.
3. Consequently, there is no justification for treating any type, or group of features
separately and no requirement for a Third Level Detail Working group as such, and this
group recommends that the national Fingerprint Board considers retaining the existing
members as the ‘Identification Working Group.’ (this group has been re-named as the,
‘Bureaux Practitioners’ Group).

Ferrier, John Kenneth
Ferrier worked for the fingerprint branch of Scotland Yard. In 1904, he was assigned to guard the
British Crown Jewels at the World’s Fair in St. Louis, Missouri. The American police officials
became interested in fingerprinting through Ferrier and for seven months he taught nine
individuals about fingerprints and the Henry System (Edward A. Evans, Emmett A. Evans,
Edward Brennan, John Shea, Mr. Ryan, Mary Holland, George Koestle, Edward Foster, and
Albert G. Perrott). During this time Ferrier also gave instruction to many others who were
interested. He is considered to be the first fingerprint instructor in the United States. Although
fingerprints had been used sporadically in the United States prior to Ferrier’s arrival, Ferrier is
credited with being the driving force behind the use of fingerprints in the U.S.

Fox, Albert Ebenezer and Ebenezer Albert (1857-19??)
The Story of the Fox twins is the English equivalent to the William and Will West story in the
United States. The Fox twins were born in St. Ippolytes, England and recognized as poachers
and petty thieves who accumulated over 220 convictions between them. Sgt. John Ferrier is said
to have used this case as an example at the 1904 World’s Fair to show how the Bertillon system
was not sufficient for identification but the Fingerprint System prevailed. Sir Edward Henry is also
said to have used this case of incorrect identification of the twins to throw out the Bertillon system
and fully adopt the Fingerprint System at the Yard in 1901. Articles regarding this case are
“Ferrier of the Yard” by John Berry, Fingerprint Whorld, 12:46 (Oct 1986) and “A Sly Pair” by D.R.
Brooker, Fingerprint Whorld, 3:11 (Jan 1978). Although this story is related to events in 1901 and
1904, it is interesting to note that the fingerprint cards in the above articles are dated Sept. 7,
1913.

Friction Ridge

Frye vs. US 1923
The court decision which states that a science can be testified to as long as the discipline is
generally accepted in the field which it belongs.

The Frye standard dates back to 1923. The Frye case involved a criminal conviction in which the
defense proposed that an expert instruct the jury by administering a systolic blood pressure test
as a means of establishing Frye’s innocence. The trial court ruled this testimony inadmissible.
The appellate court upheld the trial court’s decision, stating that the expert witness testimony
lacked “general acceptance” in its particular field, thereby establishing the Frye standard.
