No. It is the responsibility of the Criminalist to know the principles, methods and techniques of their
particular scientific field and be able to effectively communicate this information to law enforcement
personnel and in the courtroom.
Will I have to go to crime scenes if I become a Criminalist?
While this is a requirement or expectation at some forensic laboratories, not all Criminalists at the San
Diego Sheriff’s Crime Lab respond to crime scenes. Currently, a Criminalist must first volunteer to be part
of the crime scene investigation team. If he or she does volunteer, Laboratory management decides who
will be part of the C.S.I. team based upon a number of factors, including proficiency in the Criminalist's
forensic discipline, the level of training of the Criminalist in crime scene investigation techniques, and the
overall impact on the Laboratory.
What is the difference between the Criminalist position and the Forensic Evidence Technician
The Criminalist is based in the laboratory where their primary responsibility is conducting laboratory
analyses for a particular forensic discipline. Criminalists may report to a crime scene to apply their
knowledge and the scientific principles needed to aid a crime scene investigation.
The Forensic Evidence Technician (FET) is based in the field processing crime scenes. It is the FET’s
primary responsibility to report to crime scenes for documentation and evidence collection which aids in
the crime scene investigation.
Any other miscellaneous information about the Criminalist position?
In addition to extensive training within the Sheriff’s Crime Laboratory, Criminalists have many opportunities to
receive training outside of the laboratory from various agencies, including the California Department of Justice
and the Federal Bureau of Investigation. Training includes access and exposure to various advanced laboratory
methods and equipment. Criminalists may also be able to attend conferences throughout the United States.
The Sheriff’s Crime Laboratory places a heavy emphasis on customer service. Criminalists are often called upon by deputy
sheriffs, investigators, and attorneys to give advice, training, and/or presentations about the type of work done in the laboratory.
