Besides the typical, well-known crime scene investigator, you can specialize in other types of crime scene investigation. Other professions within the field include evidence technicians (ET), crime scene technicians (CST), forensic investigator (FI), scenes of crime officer (SOCO), crime scene analyst (CSA) or a criminalist officer (CO). Other fields offer a variety of opportunities to expand your knowledge about criminal investigation and the justice system.
CSIs are in charge of thoroughly documenting the crime scene. A CSI will need to collect evidence such as hair and fiber samples, analyze footprints and fingerprints and be able to sketch and photograph certain objects or events in order to re-create the crime. A CSI salary as of 2011 ranges from $20,000 to $50,000, depending on what training and education you've received and your location.
Requirements to become a CSI will vary. Some small local law enforcement agencies only require limited training while large agencies will require at least a specialized two- or four-year degree. The best way to find out what type of schooling you need is to call your local law enforcement agency and ask what they usually look for in future employees.
