Different criminal investigations will require different kinds of forensic analysis. Thus, the procedure of forensic analysis will differ for homicide and corporate data theft and it is very clear why. There are however some general common grounds that are encountered with both procedures. First of all, it is not enough to just find evidence that is acceptable in the court of law. Sometimes the nature of the evidence is versatile or perishable and the forensic investigator has to do everything to preserve it or at least to make good viable copies. Furthermore, the forensic analysis actually starts when the crime scene has been thoroughly searched by the forensic experts.
