Core Responsibilities

Primary Functions

Conducts comprehensive examinations of physical evidence to locate, develop, and preserve latent friction ridge impressions using a wide array of advanced chemical, physical, and light-based processing techniques.
Performs meticulous analysis, comparison, and evaluation of latent prints against known inked or digitally captured fingerprint and palm print standards, strictly adhering to the ACE-V (Analysis, Comparison, Evaluation, and Verification) methodology.
Operates and maintains sophisticated Automated Fingerprint Identification Systems (AFIS) and Next Generation Identification (NGI) systems, including preparing, encoding, and searching unknown prints through local, state, and national databases.
Authors highly detailed and accurate technical reports that document all examination activities, methodologies used, and the conclusions reached, ensuring they are clear, concise, and sufficient for court purposes.
Prepares and presents findings as a qualified expert witness in depositions, hearings, and court trials, clearly and effectively articulating complex scientific concepts to judges, juries, and legal counsel.
Maintains the uncompromising integrity of all evidence by meticulously documenting and preserving the chain of custody from receipt to final disposition in accordance with established laboratory protocols.
Conducts technical and administrative reviews of casework performed by peers and junior examiners to ensure accuracy, quality, and adherence to standard operating procedures and accreditation standards.
Employs advanced digital imaging and enhancement software (e.g., Adobe Photoshop) to capture, calibrate, and clarify latent print detail for analysis and comparison.
Manages and prioritizes a demanding caseload, effectively coordinating with detectives, investigators, and prosecuting attorneys to meet investigative and judicial deadlines.
Prepares and mounts courtroom exhibits, such as charts and photographic enlargements, to visually demonstrate the basis for identification or exclusion conclusions during legal testimony.
Stays abreast of the latest advancements, research, and emerging technologies in the field of friction ridge analysis through continuous education, professional literature review, and participation in workshops.
Performs regular quality control checks, calibrations, and routine maintenance on all laboratory equipment and chemical solutions to ensure optimal performance and reliable results.
Provides specialized training and mentorship to trainee examiners, law enforcement officers, and other criminal justice personnel on the proper techniques for evidence collection and preservation.
Responds to crime scenes, when required, to provide expert consultation and perform on-site processing for latent print evidence in complex or high-profile cases.
Upholds and promotes a stringent culture of safety within the laboratory, correctly handling hazardous chemicals and biological materials according to safety data sheets and established protocols.
Participates in mandatory proficiency testing and competency evaluations to maintain and demonstrate individual expertise and ensure the laboratory's continued accreditation.
Assists in the validation of new scientific instruments, software, and chemical processing techniques to enhance the laboratory's capabilities and efficiency.
Reconstructs and analyzes complex, distorted, or fragmented latent prints to determine their value for comparison and potential identification.
Manages and archives all case-related documentation, including notes, images, and reports, within the Laboratory Information Management System (LIMS).
Collaborates with other forensic disciplines (e.g., DNA, Firearms) to ensure a comprehensive, multi-disciplinary approach to evidence examination and case resolution.

Secondary Functions

Conduct statistical analysis and research on fingerprint data to support quality assurance measures and contribute to the body of knowledge in the field.
Contribute to the development, review, and validation of new and existing laboratory standard operating procedures and technical manuals.
Collaborate with law enforcement agencies, legal counsel, and other forensic units to ensure cohesive case management and information sharing.
Participate in regular team meetings, case review sessions, and quality assurance audits to foster continuous improvement and maintain high standards.
