Forensic science primarily deals with criminal investigation. This field of science relates to several disciplines in course of criminal inquiry. Forensic is an essential part of criminal investigation that needs to be judged in the court before the final verdict is stated. In fact, forensic evidence in court can cause a dramatic change in a case and point towards new dimensions in the course of action.
Another remarkable contribution of Forensic is to identify distinctiveness between firearms and projectile and at times between projectile and target. For instance, when a gun is produced in the court and is being identified as the tool utilized in the crime, then the bullet from the victim’s body is matched with the gun to see how far the evidence produced in court matches with the scene of crime. Forensic also involves tool mark identification. The science of forensic also includes explosives and tracks evidences and contributes to justice likewise:

In both cases, a forensic expert would be able to draw a fair conclusion as to what has been the actual case and forward his opinion in relation to the validity of the letter.
Forensic Personal Identification
The matter of personal identification is about how a forensic expert identifies an individual on the basis of fingerprints, DNA analysis, odontology and other sub disciplines. In many cases, a forensic expert helps in identifying a criminal by matching his fingerprints with those found on the weapon being used to commit the murder. Again, in case of female physical assault a forensic expert identifies the culprit by means of a DNA test.
