DNA forensic science is a tool used in criminal cases to free the wrongfully convicted though it has loop holes to implicate the innocent. The details and the scientific proof issued validates it use as opposed to other forms of forensic science. The complications of it in criminal investigation arises from the different forms that DNA can transferred from a person to the environment or objects that they have come in contact with.
DNA interpretations are faced with challenges related to DNA fraud an aspect that can implicate a person to crime or free the guilty individuals (Worth, 2018) . This is because of the ability of criminals to implant DNA from a different person in a crime scene. The analyst should be sensitive enough to differential false DNA samples from the real ones. This will limit the probability of errors that arise from misinterpretation. The forensic science of DNA depends on probability and thus a victim can bear different peoples DNA which they acquired differently.

DNA use requires analysis of private information and therefore, the analysts should be very cautious not to display individualized information to the public. The analysts should be aware of the challenges facing DNA usage because, the process from sample collection to reporting is exposed to the item factor where the information can be corrupted (Starr, 2016) . The forms in which the DNA entered the sample should be analyzed which might be challenging.
In conclusion, the use of DNA forensic analysis is an important intervention that is effective in the criminal investigation. Continued research should be done in the efficiency of DNA use for a person related to crime. This is to help eliminate the ability to implicate the innocent as well as the vice versa which can only be through distinguishing how the DNA entered the crime scene.
