Is a crime scene technician the same as a crime scene investigator?
Criminalistics is the science and skills of locating, documenting and collecting physical evidence at the scene of a crime so that it may be retained as evidence and/or submitted for scientific examination.
A crime scene technician is a person who performs those same tame tasks, That phrase is often used to indicate a person who is a civilian employee of the department. However "Crime Scene Technician" is also a first level of certification offered by the International Association for identification, an international society of professional police criminalists and identification specialists and forensic scientists.
A crime scene investigator is also the same thing. This phrase has been popularized by television. However, only a few departments actually use that term in real life. There are dozens of different job titles and appellations that are used to describe the same skill sets. In some places, these jobs are done by sworn police officer and detectives, and in others, they are done by civilian employees.
