Video: How Reliable Are Latent Fingerprint Examiners?

In a new video, Miami-Dade latent print examiner Brian Cerchiai talks about an NIJ-supported study conducted by the Miami-Dade (Florida) Police Department on the accuracy of fingerprint examiners.


The study found that fingerprint examiners make extremely few errors. Even when examiners did not get an independent second opinion about their decisions, they were remarkably accurate. But when decisions were verified by an independent reviewer, examiners had a 0-percent false positive, or incorrect identification, rate and a 3-percent false negative, or missed identification, rate.

Court Case Update

FINGERPRINT EVIDENCE went through a nearly three-year ordeal in the New Hampshire court system, but eventually emerged unscathed. On April 4, 2008, the New Hampshire Supreme Court unanimously reversed the decision of a lower court to exclude expert testimony regarding fingerprint evidence in the case of The State of New Hampshire v. Richard Langill. The case has been remanded back to the Rockingham County Superior Court.
