The Union County Prosecutor’s Office Forensics Laboratory, located at 300 North Avenue in downtown Westfield, is the facility at which physical, narcotics, and DNA evidence is housed, analyzed, and processed for the purposes of aiding criminal investigations in Union County.
The Laboratory was established in 1972 as the first county prosecutor’s lab in New Jersey. It received accreditation in the disciplines of Controlled Substances and Biology through the American Society of Crime Laboratory Directors/Laboratory Accreditation Board (ASCLD/LAB) in 2008.
The Technical Unit of the Forensic Laboratory is made up of two analytical sections: the Controlled Substances Section and the Biology Section. The Controlled Substances Section provides analysis of illicit drugs to support narcotics investigations and prosecutions. The Forensic Laboratory is designated by the State of New Jersey to certify drug analysis, and these certifications may be presented at trial in lieu of expert testimony. The Biology section includes DNA analysis, which provides law enforcement agencies with the establishment of human identification through DNA profiling.
The lab handles thousands of cases each year and has played an instrumental role in solving many high-profile cases, including “cold case” homicides.
