Conclusion of Circuit Court
Judge Susan Souder - Grants Motion to Exclude Testimony of Forensic
Fingerprint Examiner - Capital Murder Case: State of Maryland v. Bryan Rose
Highlights from the
Pending before the Court is Defendant’s Motion to Exclude Testimony of
Forensic Fingerprint Examiner and Request for a Frye Hearing (paper 100000,
“Motion to Exclude”). The State opposed the Motion. The Court granted the
request to have a Frye hearing and the hearing was held May 29 and 30, 2007.
Each side presented testimony of one expert to support its position. For the
reasons set forth herein, the Court will grant the Motion because the State
did not prove in this case that opinion testimony by experts regarding the
ACE-V method of latent print identification rests on a reliable factual
foundation as required by MD Rule 5-702.
The instant case is very briefly described as follows based on the State’s
summary of certain proffered evidence in connection with another motion. A
college student parked his car one day. Some days later, the student cannot
find his silver Dodge Intrepid and reported it stolen. The Intrepid was
listed on a “hot sheet” of stolen cars sought by the Regional Auto Theft
(“RAT”) police detectives.
On Tuesday, January 5, 2006 at approximately 10:00 a.m., two RAT detectives
spotted the Intrepid. They attempted to stop the Intrepid; a chase ensued.
The Intrepid got away. The driver and passenger in the Intrepid cannot be
identified except as black males.
At approximately 10:30 a.m. the same day, the Intrepid was seen in the
Security Square Mall parking lot next to the Victim’s Mercedes. A struggle
ensued. The Victim was shot by a black man who got into the Intrepid which
sped away. No one can identify the driver or passenger except as black
males. The abandoned Intrepid was eventually located at the Owings Mills
At first, no latent fingerprints were identified by the Crime Lab. Homicide
detectives suggested names of suspects to the Crime Lab. The known prints of
the suspects were compared to the latent prints recovered. Eventually, a
couple of latent prints on the cars were identified as those of the
Defendant. The identification by one Crime Lab Technician was provided to a
second Crime Lab Technician to “verify.” She agreed with the identification
of her co-worker. These opinions, that the latent print(s) on the cars match
Defendant’s prints, appear to be the heart of the State’s case.
Such a summary cannot do justice to the full presentation of evidence by the
State, nor to the cross-examination or presentation of adverse evidence by
the Defense. No facts concerning this case have been determined by the
Both sides have requested that the Court determine the issue of reliability
of the ACE-V methodology, and consequent admission vel non of the latent
fingerprints, without reference to the specific fingerprint evidence in this
case. Despite having held a hearing on the case specific fingerprint
evidence, the Court has acquiesced in the parties’ requests that the Court
determine the admissibility of latent fingerprint identification opinions
without consideration of the case specific information presented.
Whether ACE-V is a methodology which establishes the reliability of the
general practice of latent fingerprint identification.
Defendant contends that ACE-V is not a methodology which has been subjected
to scientific testing. As a result, the error rate in latent print
identifications is unknown. Absent an error rate, reliability of the
methodology is unproven. A fundamental problem, according to Defendant, is
that the subjective comparisons in ACE-V involve psychological phenomena
known as “confirmation bias.” Further, Defendant argues that the “standards”
for latent fingerprint identification are inadequate.
MD Rule 5-702 addresses the testimony of expert witnesses at trial. The Rule
provides that expert testimony, in the form of an opinion or otherwise, may
be admitted if the court determines that the testimony will assist the trier
of fact to understand the evidence or to determine a fact in issue. In
making that determination, the Rule requires the court to consider whether
the witness is qualified as an expert by knowledge, skill, experience,
training, or education . . . the appropriateness of the expert testimony on
the particular subject, and . . . whether a sufficient factual basis exists
to support the expert testimony.
In short, the court must determine whether the opinion testimony of the
expert rests on a reliable foundation.
Maryland adheres to the standard set forth in Frye v. United States, 293 F.
1013 (D.C.Cir. 1923), overruled by Daubert v. Merrell Dow, 509 U.S. 579
(1993), for determining the admissibility of scientific evidence and expert
scientific testimony. Reed v. State, 283 Md. 374, 389 (1978). Under the Frye
– Reed test, a party must establish first that a technical or scientific
method is reliable and accepted generally in the scientific community before
the court will admit expert testimony based upon the application of the
questioned technique. Montgomery Mutual Ins. Co. v. Chesson, 399 Md.314, 327
(2007), citing Wilson v. State, 370 Md. 191, 201 (2002).
Maryland appellate courts have noted that before the testimony based on the
questioned technique may be admitted into evidence, the reliability must be
demonstrated. Wilson, 370 Md. at 201. The basic “gate-keeping” obligations
imposed by the appellate courts on trial courts applies not only to
“scientific” testimony, but all expert testimony. Conaway v. Deane, ___ Md.
___, n.57 (Sept. 18, 2007) (citing Kumho Tire Co. v. Carmichael, 526 U.S.
137, 147-49 (1999). Kumho extended Daubert to non-scientific fields. In this
category, for example, are the fields that are based on observations, such
as latent fingerprint suspicion not traditional sciences such as land
valuation, drug terms, agricultural practices. United States v. Hines, 55
F.Supp.2d 62, 66 (D. Mass. 1999) (concluding that expert can testify to
similarities or dissimilarities between handwriting samples but not render
The State is correct that fingerprint evidence has been used in criminal
cases for almost a century. While that fact is worthy of consideration, it
does not prove reliability. For many centuries, perhaps for millennia,
humans thought that the earth was flat. The idea has a certain intuitive
appeal. Indeed, there still exists a Flat Earth Society for people who cling
to the idea the earth is not an orb. Armstead, supra at n.26. But science
has proved that the earth is not flat; and, it is the type of fact of which
a court can take judicial notice.
Maryland cases accepting latent print identifications in the past were not
presented with proof of erroneous identifications which refute the
infallibility claimed by the State’s expert in this case. Mr. Meagher has
stated that the FBI testifies to “a 100 percent certainty that we have an
identification.” By that, he meant that FBI agents do not go in court and
say “I believe it’s a match with 80 percent certainty or 90 percent
certainty.” Mr. Meagher claimed that there is no error rate for ACE-V. This
testimony was not credible.
The 100 percent certainty expressed by Mr. Meagher in this case, as well as
in other forum, and others has been persuasively questioned by some
academics and defense counsel. The absolute certainty has been proved to be
wrong in the past. The Mayfield case is not the only erroneous
identification. See Cooper v. Dupnik, 963 F.2d 1220 (9th Cir. 1992) and
incidents mentioned in Defendant’s motion.
The Court does not by this conclusion suggest that latent fingerprint
identification could never be admissible in another case. Future
admissibility particularly may occur since the ACE-V methodology is
changing, and as technology continues to improve.
The long history of use of fingerprint identification does not by itself
support the decision to admit it. Courts began admitting fingerprint
evidence early last century with relatively little scrutiny. Relying on
precedent, later courts simply followed. The precedent of prior admission,
rather than exacting scientific scrutiny, led to its universal acceptance.
United States v. Crisp, 324 F. 3d 261 (4th Cir. 2003) Michael, Jr.
dissenting, citing Cole (noting that fingerprint evidence became widely
accepted although “latent fingerprint identification was…not based on
scientific research at all  [but] [i]nstead…was based on anecdote,
experience, and nineteenth century statistics”) (citations omitted).
Other forms of evidence in vogue when fingerprinting began to be commonly
used were generally believed to be more credible. For example, experts in
the Bertillon technique took minute measurements of the human body to
identify criminals. The Bertillon technique is considered absurd today. See
People v. King, 266 Cal.App.2d 437 (1968) (noting that we should heed the
“tragic lessons of the Bertillon system”).
Fingerprinting rose in popularity because prints could be taken and analyzed
quickly by those with little training or experience. It emerged as a method
of identification not superior to anthropometry (the Bertillon technique),
but quicker and cheaper. Crisp, supra. The long history of use does not
itself establish its reliability.
While the ACE-V methodology appears amenable to testing, such tests have not
yet been performed. United States v. Sullivan, 246 F.Supp.2d 700, 704 (E.D.
Ky 2003) (finding expert’s testimony sufficiently reliable under Daubert).
The principles underlying ACE-V, that is the uniqueness and permanence of
fingerprints, cannot substitute for testing of ACE-V. There have been no
studies to establish how likely it is that partial prints taken from a crime
scene will be a match for only one set of fingerprints in the world. Id.
The issue is not the finding of two fingerprints that are alike, but rather
the finding of prints from two different fingers that can be mistakenly
judged to be alike by a fingerprint examination.
The Comparison of known exemplars is not at issue. In any event, while
Defendant has argued a number of reasons why general acceptance should be
discounted, Defendant has not challenged the notion that latent fingerprint
identifications have been generally accepted. Rather, Defendant’s contention
is that the reliability of such identifications have not been proved since
they have not been subjected to scientific testing.
In this case, as in others, the State introduced evidence that fingerprint
experts take and pass proficiency tests. There is no basis for a conclusion
that these tests reflect real world conditions. Crisp, supra (citations
Mr. Meagher incredibly testified that there is no error rate in ACE-V as it
is an infallible methodology. He attributed all erroneous identifications to
examiner error in applying the methodology. Mr. Meagher was neither credible
nor persuasive in this regard. Without impartial testing, however, whether
or not the methodology is infallible is unknown.
An error rate, or lack thereof, must be demonstrated by reliable scientific
studies, not by assumption. Where tests have attempted to imitate actual
conditions, error rates by fingerprint examiners have been alarmingly high.
Crisp, supra, citing Epstein:
In a 1995 test conducted by a commercial testing service, less than half of
the fingerprint examiners were able to identify correctly all of the matches
and eliminate the non-matches. On a similar test in 1998, less than sixty
percent of the examiners were able to make all identifications and
eliminations. An error rate that runs remarkably close to chance can hardly
be viewed as acceptable under Daubert.
The State did not establish in this case that there are any objective or
universal standards that govern the application of the ACE-V technique that
would establish its reliability. Mr. Meagher asserted that there were
standards, but the degree of similarity required to individualize prints is
left up to each individual examiner. Forensic experts argue: “[a]ny unbiased
intelligent assessment of fingerprint identification practices today reveals
that there are, in reality, no standards.” Crisp citing Stoney, supra.
Mr. Meagher testified that there are no minimum number of points required
for a match. The trend away from a minimum-point requirement may not be
unreasonable because the requirement is not based on scientific study.
Epstein (quoting a fingerprint expert as saying that the point system is
based on “educated conjecture”). The criteria for absolute identification
are ill-defined and little more than “the product of probabilistic
intuitions widely shared among fingerprint examiners, not of scientific
research.” Stoney; see also Cole.
Examiners are supposed to reject as matching a pair of prints that contain
even one dissimilarity according to Mr. Meagher. Yet the OIG Review
described how the experts in Mayfield believed the prints matched and so
they explained away the differences rather than discounting the match. See
also Epstein, supra at 640, cited in Crisp at 275. Nor is Mayfield the only
proven case of an erroneous identification. See, e.g., Cooper v. Dupnik, 963
F.2d 1220 (9th Cir. 1992) and other incidents of erroneous identifications
cited in Defendant’s Motion to Exclude.
The safety check in ACE-V is supposed to be the Verification phase. Any
verification which does take place is not truly independent, since the
reviewer is usually a colleague or supervisor in the same Forensic lab who
is told of the first examiner’s identification. Moreover, the reviewer is
provided only the latent and the exemplar, that is the “match” to consider.
Mr. Meagher’s testimony that this procedure is adequate to avoid erroneous
identification was neither credible nor persuasive.
In the only case to cited by either side to have considered the OIG Review,
the trial court determined that ACE-V is a reliable method; but, its
accuracy is dependent on accurate application by the practitioner. State v.
Rockingham, supra. In that case, the New Hampshire trial court held that
there was an insufficient basis for the court to find that ACE-V principles
were reliably applied. Consequently, the court refused to allow the State’s
expert to testify to her opinion regarding a single latent print recovered
because she had not documented her examination and there had been no “blind”
In conclusion, the proof presented by the State in this case regarding the
ACE-V methodology of latent fingerprint identification showed that it was
more likely so, than not so, that ACE-V was the type of procedure Frye was
intended to banish, that is, a subjective, untested, unverifiable
identification procedure that purports to be infallible. After impartial
scientific testing, the establishment of an error rate and of objective
criteria which when applied, are documented and can be verified, it may be
that latent print identification opinion testimony as offered in this
capital case will qualify for admission under Frye-Reed. The State did not
meet that burden in this case and, consequently, shall not offer testimony
that any latent fingerprint in this case is that of the Defendant. In this
case, the State did not show by a preponderance of evidence that a
fingerprint examiner can reliably identify a fingerprint to an individual to
the exclusion of all others using the ACE-V method.
