The Forensic Specialist I is the entry-level class within the forensic series. Prior experience taking and developing crime scene photos as well as lifting latent prints is required. Working under moderate supervision, this class is distinguished from the Forensic Specialist II by the performance of the more routine or less complex tasks and duties assigned to positions within this series. Gathering, preserving, interpreting and presenting crime scene evidence or processing evidence in the lab is done under close review of a supervisor and/or a full journey level Forensic Specialist II. Court testimony is limited to presentation of crime scene evidence.
