FORENSIC SCIENTIST 2

DEFINITION: This is advanced professional laboratory work in the chemical, physical and biological analysis and comparison of criminal evidence.

An employee in this job performs independent casework involving the most complex chemical, physical and biological analysis and comparison of evidence gathered and submitted by law enforcement authorities. Work is assigned in one or more of the State Police forensic laboratory’s discipline areas such as drug identification, serological examinations, blood alcohol analysis, and trace evidence analysis. Work involves selecting and conducting appropriate complex examinations for the full range of evidence associated with the assigned discipline area. Work may also include reviewing casework processed by other laboratory staff. Work involves independently maintaining a detailed record of analysis and chain of custody, preparing analytical reports associated with evidence processed, providing expert testimony at court proceedings, and maintaining laboratory equipment and reagents. Work is differentiated from the Forensic Scientist 1 job by the independent responsibility for performing advanced scientific analysis of casework characterized by a variety of evidentiary material and numerous evidence items per case. Work is assigned by a professional supervisor and reviewed by professional laboratory staff for quality, completeness, technical merit, and compliance with laboratory policies and standards.

EXAMPLES OF WORK: Performs routine and advanced scientific analysis of casework that involves the full range of evidence and examination techniques associated with the assigned discipline area.

Conducts technical and administrative review of casework processed by other forensic scientists by examining records of analysis and analytical reports to either concur with actions taken and concluded results or return for correction or further analysis.

Examines criminal evidence which has or is expected to have significant interest by the news media or judicial system.

Participates in analyses of cases that cross discipline areas.

Interacts with criminal investigators, legal authorities, and other laboratories regarding evidence to be examined and the results of analysis.

Applies physical, chemical, microscopic, chromatographic and instrumental techniques such as gas chromatography, ultraviolet spectrophotometry, infrared spectrophotometry, atomic absorption spectroscopy, mass spectrometry, energy dispersive Xray spectrometry and electron microscopy.

Examines, compares, identifies and evaluates physical evidence such as biological fluids, hair, fibers, paint chips, glass fragments, fire debris, soils, drugs, poisons, alcoholic beverages, gunshot primer residue, explosives, and obliterated serial numbers.

Identifies alcohol and determines its concentration in blood or other evidence.

Identifies controlled drug substances and related chemical compounds.

Identifies biological fluids and assesses same for potential forensic DNA analysis.

Collects, preserves, and handles evidence and documents evidence chain of custody.

Prepares detailed case records of analysis and findings that are compliant with laboratory policies and the laws governing the admissibility of evidence in court.

Testifies in court proceedings by providing facts, conclusions, and opinions regarding processed evidence.

Travels to crime scenes to collect physical evidence and document observations.

Travels to and from courts of law.

Maintains and calibrates scientific instruments common to the assigned forensic discipline.

Attends and participates in staff meetings, conferences and other training and development activities.

Reviews pertinent operational manuals, textbooks, journals, periodicals and other documents.

Performs related work as required.

REQUIRED KNOWLEDGES, SKILLS, AND ABILITIES: Knowledge of the principles and practices of quantitative and qualitative biochemical and chemical analysis.

Knowledge of biochemical, chemical and physical laboratory equipment and materials.

Knowledge of the principles of physics.

Knowledge of the practices of physical testing.

Knowledge of the procedures associated with maintaining evidence chain of custody.
