FORENSIC SCIENTIST II (FIREARMS) 2267
DISTINGUISHING FEATURES OF THE CLASS
Under general supervision, an employee in this class performs complex technical work in the identification and analysis of various types of firearms, ammunition, tools and tool marks to determine such facts as the type and operability of weapons, projectile velocity and the origin of tool marks. Work differs from that of a FS I (Firearms) in that the analyses performed are more complex than those performed by a FS I (Firearms). The work involves the use and routine maintenance of sophisticated modern laboratory equipment. The incumbent may oversee and review the work of subordinate laboratory personnel, ensure the reliability of test results, and develop and evaluate methods used in the section. May participate in crime scene investigations and issue reports of analyses performed. The work includes giving testimony at a variety of legal proceedings, and requires the exercise of independent judgment and initiative. Supervision is received from an administrative supervisor through conferences and a review of reports issued. Does related work as required.
