In cases like this, hypnosis might be the answer to unlocking the memories and leading investigators to something new. Though the method has met with some controversy, the use of a polygraph can sometimes provide law enforcement with important information on people involved in a criminal case. The key is a well-trained expert who knows how to read a polygraph and relate the findings to investigators. Forensic science offers numerous career paths to graduates. Though someone pursuing forensic science might begin their education with many of the same courses as others in the program, they will eventually specialize through elective courses that lead them onto their own path.

Here are a few of the most common forensic science careers and what students can expect if they choose to go this route. Forensic science technicians usually work in one of two areas: They go to crime scenes to collect and analyze evidence in the field, or they work in the laboratory, where they perform assessments on the evidence collected.

Both jobs require impeccable attention to detail, following proper protocol to sustain evidence chain of custody, and writing reports. Some technicians might specialize in a variety of areas, including fingerprint analysis or digital forensics. Also known as coroners, medical examiners perform medicolegal examinations and autopsies, which include locating and assessing bodily trauma, determining cause of death and identifying victims.

They might also interview those who discovered the body, evaluate photographs of the crime scene and seek out medical history information on the victim, among many other duties.

They also complete death certificates and determine the cause and manner of death. Forensic psychologists work at the intersection of psychology and the law. They often work with those in the legal system, including lawyers, judges and police departments, to evaluate those who have been accused or convicted of crimes. They might evaluate perpetrators to determine the risk of reoffending, help victims deal with the trauma they have endured or decide whether someone is fit to stand trial.

Though some do work in medical or research settings, most in this field are hands on with law enforcement issues. These forensic scientists are highly specialized in identifying, lifting and analyzing latent prints at a crime scene. Though many work at the crime scenes, some stay in the laboratory to perform detailed analysis of even the tiniest fragment of a print.

They then present their reports to the appropriate law enforcement officials. The results of their work could mean anything from a suspect being questioned to a criminal conviction. Though a criminal investigator might attend to cataloguing details at a crime scene, their primary job tends to involve interviewing witnesses or subjects, identifying needed evidence, obtaining and using search warrants, determining scope of investigations, testifying before grand juries, and conducting research or surveillance, among many other responsibilities.

A criminal investigator might be involved with a case from the moment the crime is discovered to well after a suspect has been convicted. Those who want to work as a forensic scientist will find many paths that lead to that goal. Though earning a degree in forensic science is always a great way to get started, many students will find that a degree in a related field is quite sufficient. In addition, they might be surprised to learn just how different the variety of positions in the field can be.

Here is what students need to know about becoming a forensic scientist. In the world of Hollywood, there is no difference between forensic scientists and crime scene investigators. But in the real world, the differences are profound, and the educational paths to get there are too. The vast majority of forensic scientists work in laboratories, where they analyze the information gathered by crime scene investigators.

This work involves going to the crime scene to collect evidence and analyze the space. Crime scenes can be in a wide variety of locales, from dense forests to neat and tidy apartments to bodies of water.

False Positive: When forensic science fails [Full version]

The certifications and coursework for the forensic scientist focuses on sciences, such as biology, chemistry, toxicology and the like. Although a degree in natural science or forensic science is recommended, some crime scene investigators begin as police officers and lean on their work experience to move into the investigator position. They might hold an associate degree or certificate.

Tools used are those typically found in a laboratory, including microscopes, mass spectrometers, drying cabinets, fume extractors, and specialized equipment for liquid chromatography, powder handling, liquid evaporation, toxicology, histology and more. Tools used include high-quality cameras, adhesive lift tapes or sheets, forceps and tweezers, collection bags, bindle paper, flashlights, specialized lights for revealing evidence, vials and slides, impression kits, blood collection kits and identifying placards, among others.

Forensic scientists have the option to specialize in a wide variety of areas, including latent prints, DNA analysis, ballistics, multimedia, digital forensics, toxicology and more. Crime scene investigation is a rather narrow field. The skills necessary might translate into other investigative options, such as working for the FBI or other organizations.

The education and training required for a forensic science career varies depending upon the goal of the student. These steps can give aspiring forensic scientists a roadmap of where they can expect to go over the next several years. For those who want to work in crime scene investigation, the associate degree offers a taste of what the work will entail and prepares the student to move a law enforcement position. Many criminal investigators begin their careers as police officers, and earning a degree is always helpful to an officer who wants to climb the ladder.

At this point, students will also decide what area they might like to specialize in; for instance, a forensic science technician who wants to work with latent prints or ballistics will begin taking elective courses that focus on those areas. The student who wants to take on higher levels of responsibility, such as that of a forensic psychologist of medical examiner, should start preparing for the graduate degree. An example of this is the forensic psychologist, who will focus on a psychology degree, but will also choose the forensic science concentration.

Once the degree is earned, the work is just beginning. Many who choose an advanced degree will go through several years of in-depth training or residency in order to practice in their profession. An example of this is the medical examiner, who must have a medical degree in order to practice, or the forensic odontologist, who must earn a degree in dentistry.

Those individuals will be expected to complete several years of training before moving into their forensic science roles. Training while on the job is a very important aspect of working in forensic science, as much of the work cannot be learned through a book; it must be explored through hands-on training and instruction. This training might take several months to several years. In some states or jurisdictions, forensic scientists are encouraged and in some areas, required to earn specialty certifications.

Though these certifications or credentials are not necessary to enter the profession, they can certainly open doors to better employment in the future. Potential certifications to explore include those in drug analysis, fire debris analysis, molecular biology, hairs and fibers, and paints and polymers. While not all schools have degrees in forensic science, other undergraduate degrees are useful for a person who wants to work in the field.

Here are a few of the more common degree options. The study of chemistry includes everything from learning to handle certain laboratory equipment to understanding the chemical reactions that happen in the body in response to certain substances. A chemistry program also provides a strong base in math, statistics and writing skills, all of which are vital for a forensic scientist.

This highly targeted degree focuses on sciences used daily in most forensic careers. Students can expect to become proficient in chemistry, biology, mathematics, oral communication skills, biochemistry, molecular biology and other related topics.


Those who opt for a criminal justice program can also find a home in forensic science. Students focus on the philosophy and practice of the justice system, as well as applied research methods and best practices for fieldwork. Students can opt for elective courses that focus on the natural sciences to bolster their knowledge and prepare for a forensic science career. Accreditation means a school has been evaluated by an independent body and determined to meet the standards of a rigorous, high-quality education.

When attending a program in natural sciences or criminal justice, a student can look to the school or program accreditation to determine whether the program might be a good fit. Students looking into forensic science programs can see the schools that have earned accreditation at the American Academy of Forensic Sciences. Here are a few certifications that might interest forensic science grads:. Passing of exams leads to two types of certification, depending upon the area of expertise and experience. Recent college graduates without the two years of experience required can opt for the Affiliate Status Certification, which will then award a certification upon completing the experience requirement.

Certifications are good for five years. Requirements for each program vary, but in general, certification is good for three years and completing an in-depth program and examination on the material. Typically, the applicant must be working full-time in a career that focuses on the subject of their certification, have a certain amount of education and experience, earn professional development hours and pass an examination.

For instance, students in forensic technology might focus on computer-related forensics, such as following web searches, uncovering hidden data caches, understanding software and hardware and learning techniques for extracting the maximum amount of information from them. Forensic science with a concentration in chemistry focuses on DNA profiling, instrumental analysis, analytical toxicology and courses in research. Some programs have a work requirement as well. The world of forensic science changes fast, with constantly evolving procedures and new insights into forensic analysis and criminal behavior.
