Biological Sciences

The Biological Science Section includes the DNA Casework Section as well as the New York State DNA Databank.

Casework

The Biological Science Casework Section provides submitting agencies with access to Forensic Serology and Forensic DNA Testing of selected biological materials that are associated with criminal investigations.

Forensic Serology is the identification, collection and preservation of biological materials that may be used in DNA analysis.

Forensic DNA Analysis is the process of developing DNA profiles from biological evidence to use for comparison purposes.  These profiles can be used to develop investigative leads, identify perpetrators of crimes and exonerate the innocent.  Should a suitable DNA profile be developed from crime scene evidence, it may be entered into the FBI-administered Combined DNA Index System (CODIS) for searching at the local, state and/or national levels.

DNA Databank / SDIS

The New York State DNA Databank Laboratory is responsible for processing Convicted Offender DNA samples submitted from any offender convicted on or after August 1, 2012 of a felony or Penal Law misdemeanor. Subject DNA samples are also submitted for processing pursuant to the state’s Subject regulations from offenders who provide a sample as a condition of a plea agreement, release, parole, or probation.

The DNA Databank laboratory utilize validated DNA methodologies and instrumentation to efficiently process and analyze offender DNA samples to develop DNA profiles for entry into the State CODIS Database (SDIS). CODIS is a computer database, which consists of a set of indices that electronically store both offender and forensic (crime scene evidence) DNA profiles. The offender and forensic indices are searched against each other to generate DNA matches and provide investigative leads to the law enforcement community.

The DNA Databank is administered by the New York State Division of Criminal Justice Services Office of Forensic Services as set forth in Article 49-B of the Executive Law.  Please refer to the OFS website at http://www.criminaljustice.ny.gov/forensic/aboutofs.htm for more information.

Automated Punch instruments are used to remove 1.2mm punches from an offender’s collection card to generate a DNA profile.

Buccal cells (cheek cells) is the source of DNA on offender collection cards.

Robotic instrumentation is used to streamline and automate liquid handling methods.

Forensic Scientists examine DNA profiles generated from convicted offender samples for quality and acceptability.
