The Erie County Central Police Services Forensic Laboratory (ECCPSFL) is located in the Public Safety Campus at 45 Elm Street in downtown Buffalo, NY.  The laboratory has a staff of twenty-five (25) members who serve to provide scientific support to over forty (40) Local, State, and Federal law enforcement agencies.  The laboratory is accredited in the field of Forensic Testing in the disciplines listed below by the New York State Commission of Forensic Science and ANSI National Accreditation Board.

For information regarding referral to an accredited laboratory for forensic testing that is not offered by the ECCPSFL, please contact the Laboratory Director.  The principle mission of the Erie County CPS Forensic Laboratory is to provide centralized scientific support and assistance in association with criminal investigations.  This is generally accomplished through the analysis of recovered items of physical evidence.  Once forensic scientists are consulted, they serve to provide the criminal justice system with analytical testing, formal scientific reports and opinion testimony.


Under Special Order #32 (dated March 19, 1935), former Buffalo Police Commissioner, James W. Higgins, established within the Buffalo Police Department a "Ballistics Laboratory".  The services provided by this laboratory were eventually expanded to include chemical analyses and the laboratory was designated the "Scientific Crime Detection Unit" of the Buffalo Police Department.

A study by the Erie and Niagara Counties Regional Planning Board during the early 1970's indicated the need for a single forensic laboratory to serve all law enforcement agencies within Erie County.  Consequently, in 1975, city and county government officials finalized plans to have the staff and instrumentation of the Buffalo Police Scientific Crime Detection Unit become a division of the Erie County Department of Central Police Services.  The ECCPSFL was officially established on July 1, 1975.  The Laboratory continued to operate in BPD Headquarters (74 Franklin St.) until November 2005 when it moved to the Erie County Public Safety Campus at 45 Elm Street, Buffalo, NY.
