What is Crime Scene Investigation?

Crime scene investigation is a science known as forensics. Crime Scene Investigation is the use of the physical evidence found at the scene of a crime and the use of deductive and inductive reasoning to gain knowledge of the events surrounding the crime.

The purpose of Crime Scene Investigation is to help establish what happened through crime scene reconstruction so that the responsible parties can be identified. Crime scene investigators are responsible for processing and categorizing evidence so that it can be used in criminal investigations. This might include gathering photographic evidence or physical samples from the scene, such as weapons, fingerprints, clothing, or biological evidence.

It isn’t easy to find work experience specifically in the role of a crime scene investigator. This is primarily due to vetting and health and safety requirements, and the importance of being fully trained before being given the responsibility of collecting evidence that could be used in a court of law.

Related work experience with the police is advantageous and you can gain this in several ways, including working as a special police officer, as a volunteer, or via an internship program that might start to expose you to the tasks involved in scenes of crime work.

Other related areas you could gain experience in are intelligence gathering and analysis, security services, or with a private forensic service provider. Experience in working with the public is also important, particularly as you may be working with people in sensitive situations.

Work Experience will not only allow you to obtain a deeper knowledge and understanding of the industry, but it will also give you a chance to do some essential networking with other industry professionals and gain valuable contacts for the future.

Career options

After completing a course in Crime Scene Investigation you will be able to get started in a career that uses specific knowledge of scientific concepts, law, and law enforcement.

Working hours will depend on where you have been employed and the position that you have but generally, you will have full-time working hours of around 30 to 40 hours per week. Hours of work are on a shift pattern as crime scene investigators respond to calls from the police to attend scenes of crime 24 hours a day, seven days a week, all year round. Senior crime scene investigators and managers often work more regular hours without the need to work evenings and weekends.

The work is likely to be varied and you’ll need to be prepared to expect the unexpected. A lot of your time will be spent out at the location of the scene which is under investigation, but you’ll come back to the police station to store evidence and write reports of your findings.

You’ll need to be prepared to work in different environments and will have to travel to incident scenes. At times, this will involve being in all weathers and difficult and maybe hostile situations.
