Our Forensics testing laboratory is accredited by ANAB to ISO/IEC 17025:2017 for fingerprint analysis and questioned document examination.

Our fingerprint investigative operations include using cutting-edge equipment and detection methods to process evidence collected during investigations for the presence of latent fingerprints, palm prints and footprints.  We typically process latent prints associated with investigations regarding counterfeit currency, gas pump/ATM skimming devices, and threatening letters with envelopes; however, additional evidence includes handguns, maps, paper items - and even drones – as any item found at a crime scene can potentially be processed for latent prints.  Our fingerprint examiners compare captured latent prints to known prints of individuals.  In cases when suitable prints are captured from an unknown individual, we use multiple electronic databases, called Automated Fingerprint Identification Systems (AFIS), to search for potential leads.

We are the first federal law enforcement agency to own and operate the updated 2018-model vacuum metal deposition chamber, which uses nano-technology, to process evidence items for latent prints.  This technology provides latent print detection capabilities on evidence items, such as certain plastics, should conventional methods not yield latent prints.

Our questioned document experts focus on investigations involving computer generated/enhanced documents, computer printers, printing processes, typewriting, indented impressions, and document alterations. We are the exclusive home to the Forensic Information System for Handwriting (FISH), a computer program used to digitally measure handwriting characteristics on threat letters that are compared to known handwritten threat letters in an effort to associate letters, cases, and known subjects.  Our examiners also use the Thermal Ribbon Analysis Platform (TRAP), a system designed to read the colored panels of ribbons used in thermal printers.  We identify and compare papers, fibers, inks, toners, watermarks, and materials of unknown origin.  We also maintain and use the agency's International Ink, National Inkjet and Watermark Libraries.

The majority of our questioned document examinations consist of handwriting comparisons or counterfeit related examinations; however, there are many other types of examinations that can be conducted on documents to establish their authenticity.

Our Quality Assurance and Scientific Services experts manage and maintain specialized and fundamental lab quality programs such as proficiency testing, analytical quality control and quality audits. Our experts also ensure all aspects of our lab’s quality assurance, quality control and proficiency testing programs meet agency and international accreditation guidelines.  This team also supports instrument validation and process optimization, as well as novel forensic technique development through internal research and external collaborations.  These experts provide technical support and training to our own investigators, as well as law enforcement partners regarding evidence collection and evolving forensic examination needs.

Counterfeit specialists focus on investigations involving suspect Federal Reserve Notes (currency), Silver Certificates, Treasury Bonds, and other securities. The counterfeit specialists conduct a variety of examinations, including authentication examinations, ink and paper analysis, and counterfeit currency classification. They serve as subject matter experts on the inter-agency United States Currency Program, and provide technical briefings and guidance on the latest trends in counterfeit currency manufacturing and adversarial analysis.
