Job Description
Performs a variety of standard physical, chemical, instrumental and microscopic analyses of evidence in connection with crime detection and law enforcement work; assists with more complex investigations and studies, and with assigned phases of research projects; and performs other related duties as required.
Distinguishing Characteristics:
This class differs from the Criminalist II in that the Criminalist I performs moderately complex work concerned with physical, chemical , instrumental and microscopic analyses of evidence in accordance with prescribed standards, methods and techniques , whereas the Criminalist II independently performs the full range and variety of work in connection with physical, chemical, instrumental and microscopic analyses of evidence, requiring judgment in selection of methods, techniques and instrumentation.
Classes in this series differ from classes in the Police Evidence and Identification Technician series in that the Criminalist classes are primarily concerned with the physical, chemical, instrumental and microscopic analyses of evidence in connection with crime detection and law enforcement activities; whereas classes in the Police Evidence and Identification Technician series are primarily concerned with the search, recovery, preservation, and marking of physical evidence at crime scenes.
Classes in this series differ from classes in the Chemistry series in that the Criminalist classes are primarily concerned with the physical , chemical, instrumental and microscopic analyses of evidence in connection with crime detection and law enforcement activities; whereas classes in the Chemistry series are primarily concerned with the chemical analyses of water samples and waterworks materials and substances.The following are examples of duties and are not necessarily descriptive of any one position in this class. The omission of specific duties statements does not preclude management from assigning such duties if such duties are a logical assignment for the position.
License Requirement: Possession of a valid motor vehicle driver’s license (equivalent to State of Hawaii, Type 3).
Knowledge of: The principles or general, inorganic, and analytical chemistry; the methods and techniques of chemical laboratory analysis, laboratory procedures and practices; general principles , techniques and terminology used in physical and chemical diagnoses of substances; common drugs, poisons and narcotics; uses and care of laboratory instruments and equipment.
Ability to: Conduct standard chemical and microscopic examinations , use standard laboratory instruments and equipment; analyze and interpret results of examinations and comparisons; learn to analyze a variety of substances including blood, blood stains, human exudates and excretion, drugs and narcotics ; learn to process latent prints; learn to take casts of impressions at the scene of a crime; learn to conduct ballistic tests; keep records and prepare reports of laboratory procedures , observations and findings; explain results of tests, understand and carry out oral and written instructions.
Health and Physical Condition:
Persons seeking appointment to positions in this class must meet the health and physical condition standards deemed necessary and proper for performance of the duties.
Physical Effort Grouping: Light
Special Working Conditions: Occasional exposure to obnoxious conditions as required.
