Forensic Science The word Forensic comes from the Latin forensus, meaning of the forum.1 In ancient Rome, the forum was where lawmaking debates were held, but it was also where trials were held just like modern day courthouses. From that, forensic science has come to mean the application of the natural and physical science to the motion of matters within a legal context2. Forensic Science can be viewed as a tripartite structure consisting of a Collection, which pertains to the science investigation, Examination, which pertains to the medical investigation and, Presentation, which pertains to the courts. A forensic case will involve all aspects of each of the three structured elements, each being as important as the other. It is obvious that there needs to be a shared approach for the successful end of each case. Each step in forensic science must be done in an exact order; therefore it can be assured that the investigation can have few doubts about what is being debated.

Each item when shipped should be recorded, logged and accounted for from person to person so when used in a trial, the evidence has been accounted for from beginning to end. The final thing investigators must make sure is that all evidence was seized properly and with probable cause. This is the main reason why in so many court cases evidence is thrown out, improper searches and seizures. If any investigator is in doubt on whether or not a place or person can be search, it is always best to obtain a warrant for that such reason.
