The Fourth Department, reversing defendant’s burglary conviction, determined the evidence that a partial fingerprint from the burglary scene matched the defendant was too weak to support the conviction. The conviction was therefore against the weight of the evidence:
On cross-examination, the fingerprint examiner agreed that her opinion is subjective, that two examiners may reach different opinions when examining the same set of prints, and that verification by a second examiner, particularly blind verification, significantly increases the accuracy of fingerprint analysis. She further testified that every individual fingerprint has approximately 80 to 120 classifiable characteristics, and that every characteristic between two prints must be identical for them to be considered a match. Here, because of the limited nature of the partial print, she was only able to match 18 characteristics, meaning that it matched 15% to 22.5% of the characteristics of defendant’s inked print. Further, there was no evidence presented at trial that a second examiner had made a positive verification that the partial print was made by defendant. No other evidence was introduced at trial linking defendant to the crime. People v Jones, 2022 NY Slip Op 03590, Fourth Dept 6-3-22
Practice Point: Here a partial fingerprint matched only 15 to 22.5% of the characteristics of defendant’s inked print and the “match” was not verified by a second examiner conducting a blind verification. There was no other evidence linking defendant to the burglary. The conviction was deemed against the weight of the evidence.
