How to Become a Crime Scene Investigator (CSI)

 The crime scene – a mysterious puzzle with many clues and no immediate or obvious answers. Posing more questions than answers,
 it is down to the crime scene investigator (CSI) to sift through all this information and process it.

 Clues and answers can hide in the most unexpected of places such as garden hedges, sewers, under the fingernails, it could be the
 hair left by the perpetrator as they fled the scene or even the fingerprint on the door, hitherto unseen.

 It sounds like an exciting career – and it can be – but in order to break into the world of crime scene investigation, you will need a basic  knowledge and a strong grounding in the skills and abilities needed. This is why finding the best forensic science courses are essential.
