Meanwhile on the other hand, criminal investigators are exclusively involved in intensively probing criminal cases and attempt to solve them. In criminal investigations, the investigators collect all the sufficient proof to prosecute suspects with the help of either eyewitness, physical evidence or some other possible sources.
Usually, these criminal investigators are considered as part of law enforcement officers. Their job also engages them in dangerous and challenging situations sometimes. The criminal investigators may be involved in various types of criminal cases such as:

As it is difficult to identify a person as the source of a DNA sample without looking at the whole of that person’s DNA, the comparison is made using between 2 and 13 markers.
