Core Responsibilities

Primary Functions

Accurately capture and record legible fingerprint and palm print impressions from individuals for criminal, civil, or applicant purposes using both electronic Live Scan systems and traditional ink-and-card methods.
Perform systematic classification, searching, and identification of fingerprints using established protocols like the Henry Classification System, NCIC, and state/federal automated systems.
Operate, maintain, and troubleshoot Automated Fingerprint Identification Systems (AFIS) and Next Generation Identification (NGI) systems to search for and verify potential matches of unknown prints.
Conduct detailed, methodical comparisons and evaluations of latent fingerprints and palm prints developed from crime scenes against known prints of suspects or victims.
Utilize a variety of chemical, physical, and light-based processing techniques (e.g., cyanoacrylate fuming, ninhydrin, magnetic powders) to develop and visualize latent prints on diverse types of evidence.
Meticulously document all examination activities, findings, and conclusions in detailed case notes and prepare comprehensive, clear, and concise technical reports for use by investigators and the court system.
Provide expert witness testimony in depositions and court proceedings regarding fingerprint collection methods, analysis, comparison techniques, and identification conclusions, effectively explaining complex scientific principles to a lay audience.
Photograph developed latent prints and other evidence using specialized forensic photography equipment and techniques, ensuring high-quality images for analysis and courtroom presentation.
Maintain the integrity of evidence by strictly adhering to chain-of-custody protocols from receipt through analysis, storage, and final disposition.
Perform technical and administrative reviews of other technicians' casework to ensure accuracy, completeness, and adherence to established quality assurance standards and agency policies.
Respond to crime scenes or medical examiner's offices to locate, develop, preserve, and collect latent print evidence directly from surfaces or deceased individuals.
Continuously update and maintain local, state, and national fingerprint record databases, ensuring the accuracy and timely entry of new data, expungements, and modifications.
Research and validate new fingerprint development techniques, technologies, and procedures to enhance the capabilities and efficiency of the forensic unit.
Conduct complex analysis of distorted, partial, or overlapping latent prints, applying advanced comparison methodologies to reach a conclusion of identification, exclusion, or inconclusive.

Secondary Functions

Support ad-hoc data requests and exploratory data analysis from law enforcement personnel regarding fingerprint records and identification histories.
Participate in the development and implementation of the unit's quality assurance program, including creating standard operating procedures (SOPs) and manuals.
Train law enforcement officers, new technicians, and other agency personnel on proper fingerprint collection techniques and evidence preservation protocols.
Manage and inventory all fingerprinting supplies, chemicals, and laboratory equipment, initiating purchase orders as needed to maintain operational readiness.
Assemble court exhibits, charts, and other visual aids to clearly demonstrate fingerprint identification evidence during legal proceedings.
Maintain personal proficiency by participating in regular training, competency testing, and pursuing relevant professional certifications, such as those offered by the International Association for Identification (IAI).
Liaise with external law enforcement agencies, prosecutors, defense attorneys, and other forensic laboratories to coordinate evidence analysis and share information.
Participate in community outreach and educational programs to inform the public about the role of forensic science and fingerprint identification in the justice system.
