What Is a Crime Scene Investigator (CSI)?
A Crime Scene Investigator (CSI) is in charge of extracting every possible piece of evidence from a particular crime scene. More often than not, they are employed by state or federal law enforcement, but civilians with a background in science may also be qualified for this position. These observational experts are also indispensable during trials, due to the importance of their professional testimony in the courtroom.
What Does a Crime Scene Investigator Do?
A CSI is a thorough crime scene examiner that can turn a chaotic crime scene into hard evidence. Their findings will point law enforcement officers in the right direction, and eventually, help solidify the state prosecutor’s case in court.
The very start of a crime scene investigator’s work is what differentiates this occupation from other jobs in the field of forensics. Their data collection is not done in a laboratory; it is done primarily out in the field. They must travel to a crime scene to conduct their research. Crime Scene Investigators are basically highly trained forensic scientists on call. That being said, most CSI’s work a standard forty-hour work week with standard hours, with only some variation due to specific cases.
To convert a crime scene into practical evidence that law enforcement can use, a crime scene investigator must first preserve the scene, sealing it off to make sure it is not contaminated or tampered with. If the crime scene is contaminated by a civilian or a law enforcement officer, all of the collected evidence could be considered null and void by a judge during the trial.
Then, a crime scene investigator will make precise measurements and take exhaustive photographs of any possible piece of evidence for a detailed diagram of the scene. Scales are always included photographs so that the exact size of every piece of evidence is known, no matter how minuscule or seemingly unimportant. Labels are also included in photographs to easily refer to each piece of evidence. This is all imperative for crime scene recreation and diagram drawing, which may also fall under the responsibilities of a CSI or their close counterpart, the Forensic Technician.
When everything is thoroughly documented, a crime scene investigator is tasked with packaging and preserving all pieces of physical evidence. Investigators must take extraordinary care in all facets of the job, but it may be most important here. Extremely careful collection of evidence with completely sterile equipment is imperative when it comes to the bigger picture. Everything the investigator finds is further analyzed in a forensics lab to provide further information on the role of these objects in the crime and their meaning to the prosecutor’s case. If these pieces of physical evidence are not packaged and documented correctly, they could be removed from consideration during the trial. If the pieces of evidence themselves are removed from consideration, the forensic analysis of them may be removed, as well.
Every CSI must be able to testify in court about the evidence collected at a crime scene. While on the stand, they have to ensure that the evidence found has not been contaminated or tampered with and they must ensure that the evidence was collected and documented correctly. It is also important for a CSI to be able to convey complicated findings clearly and succinctly in the courtroom so that all participants understand the meaning of each piece of evidence. If they are not able to do this, an important piece of evidence may be misunderstood by the judge or jury.
One of the most important pieces of this occupation is that a CSI must look at a crime scene objectively and analytically, without allowing the disturbing environment distract him or her from collecting helpful evidence. The gore that an investigator will almost definitely come across cannot keep them from thoroughly carrying out their duties.

Most employers are looking for 6 months - 2 years of experience in the field, and some may even provide you with this experience when you begin. Collecting evidence, then subsequently processing and analyzing the evidence are all key skills you will gain during this time.
Step 3: Earn CSI certifications and State licensure
Depending on the state, there are different requirements for state licensure as a crime scene investigator. Through theInternational Association for Identification (IAI), you can complete various certifications to further your career depending on the crime scene investigator specialty you'd like to master. Some certifications include bloodstain pattern analysis, forensic art, latent print, and forensic photography certifications.
Step 4: Higher education could provide advancement opportunities
Be aware that this is not the only route to take to become a CSI, just the most common. Some become crime scene investigators directly through the police force, without earning their Bachelor’s degree and only using their experience in the field. Having a bachelor's degree within this field and/or relevant certifications could assist you further down the road if you are looking to advance your field or specialize in a specific area of crime scene investigation.

A CSI who is a member of law enforcement can be promoted in the traditional way, through the police ranks (Captain, Lieutenant, etc.). That promotional route results in higher salary, higher rank, and it usually allows the employee to continue working with their original team.
There is also some opportunity for upward mobility when it comes to a CSI’s employer. With enough experience and success someone working for local law enforcement, an investigator could pivot into working for a government agency like the FBI. That kind of employment would generally garner a raise in salary.

This gives them the ability to transfer into different departments within the police force. If a CSI decided their skills would be more helpful somewhere else, they could transfer fairly easily between departments because of their completed Police Academy experience.
