PRINCE GEORGE’S COUNTY, Md. (7News) — More than 100 criminal cases are being reviewed by Prince George’s County officials after an internal audit found inconsistencies in the fingerprint work of a single police forensic examiner.
The Prince George’s County Police Department said the issue was first flagged on Dec. 2, 2025, when supervisors in the Latent Print Unit noticed two cases with incomplete comparisons and potentially valuable fingerprint impressions that had not been examined. The discovery prompted a broader review of the unit’s work.
That audit identified concerns limited to one examiner whose casework spanned roughly 300 cases between June 2021 and May 2025.
According to law enforcement sources, the concern is not only that some fingerprint comparisons were incomplete, but that potential additional suspects may have gone unidentified because certain impressions were never processed.

The department ultimately determined that 134 cases required reexamination due to differences in expert opinion about the examiner’s work. An independent external laboratory was brought in to review selected cases. That reexamination found no erroneous identifications and confirmed that all latent evidence had been available at the time of the original analysis, officials said.
The State’s Attorney’s Office was formally notified, and disclosures to defense attorneys in pending cases have already started. County officials said disclosures will be made in all charged cases in which the examiner conducted fingerprint analysis.
Chief Nader has since implemented a new policy requiring peer review at all stages of latent print casework — a step the department says goes beyond standard industry practice.
County Executive Braveboy said in a statement, “Accuracy and accountability in forensic work are essential to maintaining public trust. Our residents deserve a justice system that is both fair and reliable.”
