The most important part of any criminal hearing is evidence. The court relies on it heavily when it comes to making a judgment on whether a particular party is guilty of a crime or not.
It is the role of a criminal investigator to find relevant evidence to a particular crime. Investigators will use the knowledge they gained while taking their criminal investigation course to collect data that can back up any claims against whoever is being prosecuted.
That said, here are the different types of evidence a criminal investigator can collect or use:
This type of evidence can be described as the data sought after first as a person tries to prove a point. A good example would be when one tries to back up a statement, such as why chewing sugarless gum is important. He or she could state that four out of five dentists advise that we should chew sugarless gum. Each time numbers are involved in proving a point, it is referred to as statistical evidence.
This is perhaps one of the most underutilized forms of evidence. Anecdotal evidence is based on a person’s view of the world. It plays a major role when it comes to disproving generalizations. Personal observations are best suited for introducing a certain topic and building upon it. Anecdotal evidence is stronger when backed up by statistical evidence.
This is evidence based on what a person saw or experienced. A good example is when a company asks one of their consumers to give a testimony on the quality of their product based on the experience they had while using it. Students who quote an authority as the source of information on their essays are all relying on testimonial evidence.
The evidence is only useful if obtained in a legal manner and if it is true. Persons who give false testimonies in court are often said to have purged themselves and may face jail time if prosecuted.
