Evidence Technician

Evidence Technicians are police officers who have received advanced training in the identification and collection of evidence. Large agencies sometimes employ evidence technicians who do not perform patrol functions, but these are rare. Except in very large agencies, they work a regular patrol or investigative shift, and are called to crime scenes when their services are needed.


Evidence technicians must be able to work independently and in a wide variety of settings. Unlike television depictions, crimes scenes are often chaotic and physically unpleasant, so a real ET must be able to work carefully and methodically despite the surroundings.


Agencies with their own crime lab, such as the Michigan State Police, usually require a degree in a science (such as biology, botany or chemistry) for lab personnel. These agencies give hiring preference to those within the department who possess a needed skill. For example, a Michigan State Police trooper with a degree in chemistry will have the best chance at obtaining a lab assignment if a chemist position becomes available.
