Crime Scene Investigator
How to Become a Crime Scene Investigator
A crime scene investigator, or a CSI, is called to action shortly after the crime occurs. They photograph, diagram, and document the crime scene and collect and preserve evidence. The CSI is then required to turn the evidence they collect over to the crime laboratory. Here, forensic scientists perform laboratory analyses that will hopefully reveal the nature and cause of the crime.
A crime scene investigator may be responsible for:
- Documentation of the crime scene, including photos
- The collection of physical evidence such as: fingerprints, footwear impressions, hair & fibers, and biological fluid
- Discovering DNA and conducting a blood spatter pattern analysis
- Following protocol for the packaging and securing of the evidence collected from the scene
- Attending autopsies and assisting the pathologist with collection of physical evidence from the body
- Taking thorough notes to later complete a comprehensive written report
- Giving an accurate and comprehensive testimony in a court of law
Crime scene investigators often start in a different law enforcement position. Some are detectives or agents working at the various levels of government. Local police officers with six months to three years of experience may also be promoted to a CSI.
Crime Scene Investigator Education Requirements
The best route to becoming a crime scene investigator is to become involved with law enforcement. Although some police departments do hire civilian CSIs, most are looking for investigators with a policing background. To be qualified you would need at least an associate’s degree, however many police departments do require applicants to have a bachelor’s degree.

Requirements to become a crime scene investigator are agency specific, so it is important to contact the hiring employer to see what you can do to be better qualified for the job. In general, the more college education and experience you have, the more attractive you are to hiring police departments.
