There are no particular courses to study or engage in order to become an investigator. It is a skill - you either possess the aptitude and propensity, or you do not. Once you have become an investigator there are opportunities for scholastic enhancement of your natural talents and skills. Very-very seldom is someoine hired directly into a law enforcement agency as an investigator. Everyone starts off on the lowest rung of the ladder and, through experience and practical application of their innate skills, those who aspire to become investigators will start to stand out and they will be developed and urged along that career ladder.
