Imagine getting a telephone call in the middle of a brisk winter night to meet police at the wharf where a decomposing body has been discovered. Foul play is suspected, and you are needed immediately to process the crime scene. If this scenario sounds irresistible to you, a career in forensic science may be worth investigating. Your training would entail learning proper legal procedures for collecting samples and maintaining a chain of evidence that would hold up in court. Being a crime scene investigator (CSI) holds great responsibility because forensic mistakes can unravel the prosecution’s case.
Investigating a crime scene requires integrity, logic, natural curiosity, keen observation, attention to detail and problem-solving ability. CSIs, also called forensic science technicians, are responsible for collecting evidence without contaminating it. Depending on the nature of the crime, duties may include photographing blood splatter evidence, making tire and footprint castings, bagging hair and fiber samples for testing, and lifting fingerprints. CSIs may draw sketches in an attempt to reconstruct the crime scene. Back at the crime lab, the crime scene investigator or a more highly trained forensic expert examines tread marks, bone fragments, DNA and bullet casings. They use computers to search police databases. Excellent written and verbal skills are required to write detailed, objective reports and to testify in court about evidence-collection procedures and findings.
Although two-year degrees in forensics and criminal justice are available, most crime scene investigators have a minimum of a bachelor’s degree in natural science or forensic science. They take classes such as biology, anatomy, statistics, chemistry, forensic techniques and criminal justice. Many technicians major in a science such as biology and then pursue a master’s degree in forensic science, where specializations are offered in areas such as toxicology and pathology. Jobs in this field are highly competitive, and some agencies favor applicants who are already sworn police officers or qualified to attend their police skills academy. On-the-job training is mandatory. State requirements vary, and some jurisdictions prefer additional testing, certification or licensing.
According to the Bureau of Labor Statistics in 2017, the median annual salary of a CSI is $57,850 or $27.81 per hour. Half of all CSIs earned less and half earned more. High earning potential is possible with skill and experience. CSIs in the top 10 percent wage bracket earn more than $95,600 annually.
Most CSIs are employed by state and local governments where their duties and responsibilities focus on collecting DNA, fibers and other evidence at crime scenes. Working outdoors in inclement weather is expected of CSIs along with frequent evening work and required overtime. Forensic science technicians based in labs usually work normal business hours, except when they are on call, when case police need evidence analyzed right away, or when their presence is required on-site.
Years of Experience
Emphasis is placed on practical training under the supervision of a skilled CSI trainer and mentor to attain real-world experience outside the crime lab. Seasoned crime scene investigators who are unflappable in court may enjoy outstanding reputations and charge higher consulting fees. Even the best CSIs can never rest on their laurels. Continuing education is essential to stay abreast of emerging technologies and software programs.
Job Growth Outlook
The Bureau of Labor Statistics indicates that the demand for forensic science technicians, which includes CSIs and forensic lab technicians, will increase 17 percent between 2016 and 2026, faster than average. Nonetheless, competition will be keen because the job is popular due to TV crime shows, and the forensic field is small – only 2,600 new jobs will be created over the decade.
