Cybergenetics congratulates Chemung County District Attorney Weeden Wetmore on his recognition as an Outstanding Prosecutor by the New York State Bar Association. DA Wetmore has served in the District Attorney’s office for 37 years.

DA Wetmore has secured over 100 guilty trial verdicts, many in serious and violent cases. Mr. Wetmore has been a leader in using new forensic methods. In 2015, he successfully prosecuted a serial rapist, Casey Wilson, using automated computer interpretation of complex DNA evidence for the first time in a New York trial. Cybergenetics performed the TrueAllele Casework analysis, statistically placing Wilson in DNA mixtures on a pair of purple gloves.

At the time, the New York State Police DNA laboratory used limited human review methods. They were unable to report results on 70% of their DNA mixture evidence items, including these gloves. But TrueAllele got the answers. Cybergenetics' accurate and automated computer separates mixtures into simpler genotypes that are easy to explain.

Cybergenetics Chief Scientist Dr. Mark Perlin testified before the NY v. Wilson 2013 grand jury, again at trial, and later at a successful admissibility hearing. We use the Wilson case to teach how to present understandable DNA mixture evidence in court.
