National Academy of Sciences Report - See pp. 136-150 for the National Research Council's assessment of the discipline of fingerprint analysis. The 2009 NAS Report cited "a thorough analysis of the ACE-V method" that concluded: "'We have reviewed available scientific evidence of the validity of the ACE-V method and found none.'" pp. 142-143 (citation omitted).
Scientific Working Group on Friction Ridge Analysis, Study and Technology (SWGFAST) - a collaboration of American and international forensic science laboratories and practitioners collaborating to improve discipline practices and build consensus standards for the field of friction ridge analysis.
- NIJ Fingerprint Sourcebook - This National Institute of Justice publication was prepared by SWGFAST in 2011. All 15 chapters are available for free online. This publication sets standards for fingerprint identification and addresses issues such as bias and reliability of the technique.
UK Fingerprint Source Book - this reference document drafted in March 2013 describes in detail the various techniques used for developing and comparing fingerprints. Provides more historical and scientific information about the techniques used to develop fingerprints than most lab standard operating procedures do.
International Association of Identification - Professional association for forensic identification disciplines including fingerprint analysis.
- Motion to Exclude Latent Fingerprint Testimony (Filed 10-30-2009 in Superior Court of the District of Columbia) based in part on the NAS report, argues that "the relevant scientific community does not generally accept that latent fingerprint analysis can reliably and accurately demonstrate a connection between a latent print and a specific individual."
- Sample Motion to Exclude Latent Fingerprint Testimony - NC motion drafted in 2011 based on NAS report, uses the Howerton/Goode standard and Rules of Evidence 702 and 403. Please note that this motion is based on the Howerton/Goode standard and not the new Rule of Evidence 702. The new Rule of Evidence 702 may contain additional avenues to challenge the admissibility of expert testimony. For cases with a date of offense on or after October 1, 2011, attorneys should update this motion to use the new Rule of Evidence 702 standard. Also, not all possible case law that may be cited is included on this website. NC attorneys seeking to challenge the admissibility of fingerprint evidence testimony should contact Sarah Olson before filing this motion.

- Attorneys should be aware of the following cases involving fingerprint misidentification or fingerprint evidence used to exonerate:
- Lana Canen case - Ms. Canen's 2005 murder conviction in IN was overturned in Nov. 2012 after she spent eight years in prison. A fingerprint that was a crucial piece of evdience in the prosecution's case against her was found not to be hers. An Arizona fingerprint expert discovered that a sheriff's detective misidentified a fingerprint found on a pill bottle in the victim's home.
- George Allen case - Mr. Allen's 1983 rape and murder conviction in MO was reversed in Nov. 2012, though the state is appealing the reversal. In this case, it was discovered that there are seven usable fingerprints from the crime scene that do not match anyone involved, though police testified at trial that the fingerprints matched the victim, the victim's boyfriend, or the police office who responded to the scene.
- Willie Grimes case - A three-judge panel in NC decided Mr. Grimes was innocent of a 1987 rape conviction for which he had served more than 24 years. Fingerprints from the crime scene did not match Grimes, but the State withheld that evidence until the trial. In 2011, the prints were uploaded into the Automated Fingerprint Identification System and there was a hit to the original suspect in the case.
- Brandon Mayfield Case - In May 2004, the FBI arrested Oregon lawyer Brandon Mayfield based on an erroneous fingerprint identification. FBI analysts incorrectly identified a fingerprint left inside a plastic bag related to the Madrid train bombing as matching Mr. Mayfield.
- If an attorney would like a list of additional fingerprint error cases for use in a motion, email Sarah Rackley Olson.
- In cases where fingerprint evidence is the only evidence connecting the defendant to the crime, attorneys should consider the Irick rule. State v. Irick, 291 N.C. 480, 491-492 (1977) holds that "[f]ingerprint evidence, standing alone, is sufficient to withstand a motion for nonsuit only if there is 'substantial evidence of circumstances from which the jury can find that the fingerprints could only have been impressed at the time the crime was committed.'"
- State of New Hampshire v. Richard Langhill - NH Supreme Court held that an ACE-V examiner cannot testify about the verification of the examination performed by a non-testifying examiner because it is inadmissible hearsay.
- State v. Zajac, District Court for the District of Utah, Central Division
- Zajac Order - granted in part and denied in part the Defendant's motion to exclude fingerprint evidence. Important example of how the language used by the fingerprint examiner can be limited.
- Memo in Support of Defendant's Motion to Exclude Fingerprint Evidence
- State v. Rudolph, Northern District of Alabama (Daubert jurisdiction)
- Motion to Exclude Testimony of Forensic Fingerprint Examiner - includes a comprehensive history of what scientific validation has and has not been completed for this field. Critiques the lack of uniform standards. Critiques analysis of small or distorted latent prints.
- Affidavit of Simon Cole - This expert in the field of fingerprint analysis describes the problems with the reliability of fingerprint evidence and the lack of uniform standards in the field.
