What is CSI?
CSI stands for Crime Scene Investigation. It is the practice of gathering physical evidence at crime scenes to determine what happened and who was involved. Professionals in this field are often referred to as crime scene investigators, CSI agents, or crime scene examiners. The field involves the application of scientific principles and forensic techniques to criminal investigations.

It is a vast field with several specializations in concentration areas, including:
- DNA analysis
- Fingerprinting
- Ballistics analysis
- Toxicology analysis
- Blood spatter analysis
- Digital forensic
- Gunpowder analysis
Through the application of scientific theories and principles, Crime scene investigation specialists aim to reconstruct the sequence of events, document their findings in the way prescribed by law, and present their findings to the court. Analyzing the crime scene and identifying evidence requires more than just good observation skills.
It is a field that requires great skill, not just in forensic science, but also in criminology, as an understanding of criminal behavior can help CSI examiners recreate the crime scene and events accurately.

What does a CSI do?
The crime scene detective job description is rarely ever the same in two cases. For example, if the detective on a case has a forensic science background, the responsibilities of crime scene investigation may be divided as they are likely to coordinate closely with the crime scene investigator. According to the standard crime scene investigator definition, these professionals are responsible for:
- Outlining the crime scene to prevent contamination
- Processing crime scenes
- Photographing and sketching the crime scene
- Collecting physical evidence
- Preserving it to prevent contamination –
- Documenting findings
- Documenting the chain of custody
- Recreating the crime scene and the chain of events
- Submitting reports to law enforcement
- Testifying in court
While the technical aspects are crucial, understanding why a crime occurred, what motives, patterns, or psychological factors were at play, can significantly influence how evidence is interpreted. A successful CSI does not just look at the evidence and take it at face value. If they find a bullet casing, they will try to determine its trajectory, the positioning of the shooter, their mental condition, the victim’s actions, and even their state of mind.

This is where understanding criminal behavior becomes an invaluable asset. It not only offers insights into the motivation and psychological condition of a criminal, but also the victim and the witnesses, which can provide valuable insights into what exactly happened.
What is the role of psychology in crime scene investigation?
Even though an education in criminal psychology is not a prerequisite or an outright requirement, it can truly benefit your career as a Crime Scene Investigator. As outlined above, the job of a crime scene investigator is not as black and white as it may appear. They must not only see the obvious but also try to find the hidden by connecting the dots, using raw logic, and a deep understanding of criminal behavior.

While it’s not a formal requirement, many experienced professionals believe that a solid grounding in criminal psychology can enhance a CSI’s capabilities. Understanding behavioral patterns can help in:
- Anticipating where additional evidence may be found
- Distinguishing between accidental and intentional actions
- Identifying the staging or manipulation of a crime scene
- Narrowing down suspect profiles
For example, a staged burglary scene may appear legitimate at first glance. However, knowledge of behavioral red flags, like undisturbed valuables or selective damage, can alert a CSI to possible deception. These insights often come from studying patterns in criminal behavior through criminal psychology.

When researching the best degrees for CSI, consider programs that offer interdisciplinary coursework in both science and criminal behavior. A CSI degree that includes forensic psychology, for instance, provides a competitive edge.
Obtain training and certifications
Hands-on crime scene investigation training is another non-negotiable requirement to enter the field. Whether you look at a CSI job description or that of a CSI forensic scientist, you will soon realize it is not a desk job. It is definitely a field job where you will have to visit crime scenes, collect evidence, bring it back to the lab, analyze it, and document and present your findings to the court. Moreover, you may also be called into court to testify and defend your findings.
Many aspiring CSIs attend police academies or forensic science programs offering internships and practical lab experience. Here are some certifications you can explore:
- Crime Scene Investigator Certificate Program at California State University, Long Beach
- Crime Scene Investigation – University of California, Riverside

These will help you get entry-level Crime Scene Technician jobs. With more experience, you can go on to roles such as CSI Forensic Scientist, Crime Scene Analyst, Forensic Technician and other supervisory roles.

Is forensic science the same as crime scene investigation?
Is forensic science the same as crime scene investigation is a very common question. It is, in fact, very easy to confuse the two fields. However, there are some key differences between the two. Crime Scene Investigation is primarily a site-based position focusing on on-site evidence collection and analysis, including crime scene analysis and photography.
Whereas forensic science involves laboratory-based analysis of the evidence that crime scene investigators collect. Moreover, forensic scientists collaborate with specialized professionals such as toxicologists and ballistics experts for a detailed analysis of the evidence.
Related: What are the courses needed to be a forensic scientist?
Some professionals do attempt to develop competencies in both fields to become both a CSI Forensic Scientist and a CSI Investigator. The dual competency can expand your career options.
What hours are required to work for crime scene investigator?
Criminals don’t have set working hours like corporate employees. Thus, neither do crime scene investigators. Investigators are often on-call, working nights, weekends, and holidays. If you are wondering what hours are required to work for crime scene investigator roles? We suggest you keep your expectations realistic. You will be working irregular shifts and long hours, especially for complex or high-profile cases.
Do CSI work with detectives?
Yes. Collaboration is key in criminal investigations. Do the CSI work with detectives? Absolutely. CSIs work closely with law enforcement detectives to ensure that the scene is thoroughly processed and that all findings are accurately documented. While the CSI handles physical evidence, the detective pieces together the human narrative. When both professionals understand criminal behavior, their collaboration becomes more seamless and productive.
