Criminal investigators analyse evidence, perform searches, conduct interviews with witnesses and undergo surveillance to solve crimes, identify and arrest suspects, and prevent future criminal activities. They typically work for local, state/provincial or federal law enforcement agencies.
Nights, weekends, holidays occasionally
Criminal investigators generally work Monday to Friday, but their hours will be typically longer at the start of an investigation because they need to gather as much fresh evidence as possible and track new leads as quickly as they can. On occasion, you could clock in 20 consecutive hours, and you may be subjected to respond to crime scenes at all hours of the day.
As a criminal investigator, you will work in all sorts of environments during your shift, including at a police station, at a crime scene, in a laboratory and on the road to talk to witnesses, interview relations and arrest suspects.
Annual salary estimates are based on percentile wage data collected through the Occupational Employment Statistics (OES) survey of US workers.
DVM / VMD degree
You will generally need a high school diploma to become a criminal investigator, although some agencies may require a college degree in law enforcement, criminal justice or a related subject. You will then need to complete specialist training and supervised experience in areas such as patrol, self-defence and firearm use.
Most criminal investigators start as police officers. With experience, they can advance to a management role within the same department or to higher roles within law enforcement.
