New York City is building a vast, unregulated DNA database that police are already using to connect suspects to evidence from crime scenes across the five boroughs.
In the last five years, the number of DNA profiles in New York's local database has grown dramatically, driven in part by a push to collect DNA in every gun case. As of July, the Office of the Chief Medical Examiner was storing about 64,000 genetic profiles, The Trace and WNYC have learned.
Details about the size of the database and its rapid growth have not been previously reported.
