The U.S. Postal Inspection Service maintains a state-of-the-art National Forensic Laboratory in Dulles, Virginia, that houses highly-trained forensic scientists and technical specialists. These experts play a key role in the identification, prosecution, and conviction of individuals responsible for postal-related criminal offenses. Several units are part of the National Forensics Laboratory.
All the units provide support to the field through participation in the Forensics Laboratory Service Incident Response Team, which will respond and assist inspectors with collection and processing of major crime scenes and violent crimes.
