A type of DNA testing done by the New York City’s Office of the Chief Medical Examiner for almost 10 years does not have enough acceptance in the relevant scientific community to make its findings admissible, a judge has decided.

After about two and a half years of litigation, including live testimony from 11 scientists, Acting Brooklyn Supreme Court Justice Mark Dwyer decided not to admit so-called “lower copy number” or “high-sensitivity” analysis. Dwyer said that the New York Medical Examiner is the only public laboratory in the United States that employs the technique in criminal cases.
