Latent Print Section

The Latent Print Section was established in 2011 and was accredited by the American Society of Crime Laboratory Directors/ Laboratory Accreditation Board (ASCLD/LAB) for latent print comparisons in 2012.  The ultimate goal of latent print examination and comparison is to identify friction ridge impressions from the fingers, palms, and soles of the feet to the source that produced them.  If no subject information is available, latent prints may be searched through the local Nassau County Automated Fingerprint Identification System (AFIS) and/or the State Automated Biometric System (SABIS). The Latent Print Section may assist in crime scene processing when requested.
