Forensic science technicians — also known as crime scene investigators or crime scene technicians — work to solve crimes through analyzing evidence from a crime scene. In a criminal investigation, they're responsible for gathering and analyzing evidence from the scene of a crime and crafting a report that can be used to determine what the evidence means for the case.
While some forensic science technicians do both, most of them specialize either in working on location at the crime scene collecting evidence, or in the lab inspecting and cataloging it. Forensic science technicians on the crime scene must first assess the scene to determine how best to collect evidence without tampering with the environment. They then dust for fingerprints, collect and catalog weapons or fluids, take photos, sketch the scene and package evidence for safe transport to the lab. They may also help recreate the crime scene with law enforcement officers to piece together the missing parts of a case.
Through analyzing physical evidence, crime scene investigators can uncover facts and make conclusions about a case. Working in forensic science allows you to work at the intersection of science and criminal justice, using a background in math and natural science to enhance the work of law enforcement.
There are a few different paths to a career as a forensic science technician. However, there are some core requirements everyone has to pass in order to get the job, and a few key experiences that can help you get ahead in the job market.
Though not a requirement, having a relevant internship on your resume will help you stand out to a hiring manager. Completing an internship in forensic science will show you are familiar with what it takes to work in and around a crime scene and have a demonstrated interest in the work. Depending on the internship, it can also help you get acquainted with the technology and procedures forensic scientists must learn to use. This puts you ahead of the game in the training department and shows you already have a knowledge base to start from.
In order to become a forensic science technician, you typically need a bachelor's degree in a natural science, such as biology or chemistry. You could also study forensic science directly, though not all colleges have specialized undergraduate programs in the field. If you study a discipline outside of forensic science, though, it's a good idea to take as many classes as possible in or related to forensic science. Many forensic science technicians go on to get a master's degree in forensic science after their undergrad education, but this is not a requirement for the job. Within a postgraduate program, you can typically choose to specialize in an area of study, such as DNA, pathology or ballistics. There's also an option to get a doctorate degree in forensic science, but this is not standard.
Some forensic science technicians that work within police departments start as police officers, so they have completed police academy training. However, this isn't a requirement, and many forensic science technicians are civilians. Forensic science technicians new to the field have to learn the proper procedures and correct methods for gathering and cataloging evidence, as well as keep up-to-date with the newest technology in the field for inspecting and analyzing material. This training happens mostly on the job, with trainees working under a more experienced technician before being assigned to cases on their own.
While they are not mandatory, different licenses and certifications can enhance your expertise and verify your proficiency in different areas of forensic science, like blood stains, DNA analysis, latent prints or crime scene photography. Depending on your specialized skills, you can be eligible for senior-level positions and higher salaries.
