Crime scene investigators are important to helping keep society safe and helping law enforcement solve crimes. Learn more about becoming a CSI below. 

Nearly 8 million property crimes occurred in 2016, according to the FBI, leading to an estimated total of $15.6 billion in losses, and the number of violent crimes nationwide topped 1.2 million the same year. Those are daunting numbers, to be sure, but professionals with criminal justice degrees in crime scene investigation can help control them.

Crime scene investigators perform some of the most mentally vigorous work required of graduates with criminal justice degrees. The duties of the job, whether from a forensic science or detective/criminal investigation angle, include:

  • Discovering and labeling evidence
  • Conducting on-site analyses or interviews
  • Synthesizing available information into detailed reports for later review
  • Reconstruction crime scenes
  • Sifting through online, public and court records to uncover clues

Depending on the region and the exact position, crime scene investigators (CSIs) may also be known as criminalists or forensic science technicians.
