What is a Crime Scene Technician and What do They Do?


A career as a crime scene technician (CST) can be as exciting as it is rewarding. These law enforcement professionals hold positions similar to crime scene investigators (CSI), forensic science technicians, or crime scene analysts as you may have seen in popular TV shows in recent years. They might visit crime scenes to gather evidence of a crime. This can involve blood spatter, bodily fluids, and other grisly details. Crime scene technicians also take lots of photos at crime scenes, create composite images of lost people, and help track down fugitives. While this profession has received a lot of attention as a result of various television shows that glamorize the field, the reality of it is quite different than the TV version. Nevertheless, professionals in the field find that their work is rewarding and exciting. To become a crime scene technician, you won't have to necessarily attain a degree, but a certificate of some sort will certainly help you advance.

Steps to Becoming a Crime Scene Technician


A crime scene investigator or technician is a law enforcement professional who collects physical evidence from crime scenes. They use specialized training to analyze fingerprints, bloodstain patterns, and present findings in court. Crime scene technicians are skilled in various forensic methods to ensure the integrity of the evidence they collect.

Crime scene technicians analyze evidence from crime scenes, spending long hours in the lab but also working closely with their team. They coordinate with detectives and police officers to recreate crime scenes and help solve cases. Technicians may also present their findings in court.

Crime scene technicians must be meticulous with the samples they handle, as forensic methods are continually tested for accuracy. Defense attorneys will often try to discredit evidence, and if the chain of custody is compromised, it could result in a criminal walking free.

Additionally, you will need to complete a training program and then pass an examination.
  • Forensic Art Certification:
    This aspect of crime scene investigations involves collecting descriptive data from witnesses and compiling a composite sketch or other image of a criminal perpetrator or even a lost person. The field has evolved to include computer modeling software that can digitally emulate aging or other alterations to a person's appearance. To qualify for the written exam and practical test applicants need to complete approximately 150 hours of training and two years of experience as a forensic artist.

  • Latent Print Certification:
    Fingerprint evidence often is able to crack a case wide open. When a criminal leaves their fingerprints at the scene of a crime, investigators have probable cause to continue to consider them a suspect. To receive a Latent Print Certification, the educational requirements are a bachelor's degree and two years of experience or a high school diploma and four years of experience. Those with an associate degree need three years of full-time experience.

Step 4: Continuing Education and License Maintenance

Crime scene technicians can advance their careers by increasing education and earning certifications through the IAI. These certifications, such as analyzing footwear impressions, collecting latent fingerprints, or creating forensic artwork, allow technicians to specialize in specific areas. This enhances their skills, increasing both salary potential and responsibilities.

Those who have professional certifications will be sure to continue their education because they will need continuing education units (CEUs) to renew their credentials. Some certifications require as many as 80 CEU credits to renew a credential. They then need to pass a written test to affirm that their knowledge is current and to the standards of the issuing body. When crime scene technicians renew their certificates, they are sure to remain current with the ever-evolving forensic sciences and associated crime scene technology.

There is also the option of returning to school for an academic degree. Crime scene technicians might consider pursuing an associate, bachelor’s, or master's degree in biology or chemistry. This option can take them up the ladder in their lab and police department and each greater degree will help with professional certifications. Specializations such as genetics or toxicology can help them become even better technicians and investigators.
