Under general supervision, an employee in this class performs complex chemical, microscopic, physical, and instrumental analyses of paint, glass, soil, hair & fibers, fire debris and other trace evidence, examines and compares tire and footwear impressions, prepares cast impressions and performs tests on other physical evidence removed from crime scenes.  Work differs from that of a FS I (Trace Evidence) in that the analyses performed are more complex than those performed by a FS I (Trace Evidence).  The work involves the use and routine maintenance of sophisticated modern laboratory equipment. The incumbent may oversee and review the work of subordinate 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.
