Division of Forensic Services

The Division of Forensic Services (DFS) is an entity of the Nassau County Office of the Medical Examiner (NCOME) which is headed by the Chief Medical Examiner, Dr. Tamara Bloom. The NCOME crime laboratory was first established in 2001 and accredited in 2003 for forensic DNA casework analysis as the Department of Forensic Genetics. The laboratory remained a single discipline laboratory until 2010 when it added a latent print and chemistry section. Currently the DFS encompasses four distinct sections, Biology, Latent Print, Chemistry and Quality Assurance section which make up the NCOME Crime Laboratory.


The mission of the NCOME DFS is to supply the criminal justice system and community of Nassau County with a state-of-the-art Forensic testing facility.  The laboratory’s technical operations and overall management system conform to the requirements of the ASCLD/LAB-International® Accreditation Program, the FBI Quality Assurance Standards for Forensic DNA Testing Laboratories, and the National DNA Index System (NDIS).  The laboratory will conduct scientific analysis on evidence related to criminal and civil investigations within the scope of the laboratory’s accreditation.  These analyses will be conducted independently and objectively, to provide accurate, reliable and timely results to the legal system of Nassau County.  To comply with the laboratory’s mission, the DFS will ensure accurate and reliable results through its quality assurance program.
