What is evidence analysis?
Evidence analysis represents sorting, corroborating, and linking evidence and facts to prove, disprove and weigh competing theories related to a criminal trial. Any of the documents or material submitted to the tribunal in case of the allegation to ascertain the truth of fact under investigation is termed as evidence.
Trace evidence analysis
Trace Evidence Analysis is forensic science that deals with all small pieces of material collected from crime scenes and accidents. Usually, these materials cannot be seen with the unaided eye. Therefore, experts use a combination of both microscopic and instrumental analyses in all cases.
Evidence found at the scene of a criminal act, obtained through an audit procedure, or obtained at the request of a court, must be identified, marked, listed, and preserved in its original condition with the establishment of supervision until they are brought to court. Otherwise, if there were abuses and omissions concerning management or possession, such evidence could be challenged or rejected because it was not presented in court in its original condition, questioning its authenticity and validity.
When investigators come into possession of the original document, they may in some way mark such documents by printing the initials or the date of the seizure itself in the corner or back of the form to confirm their authenticity in court192. Also, after making a copy of that document, investigators can leave it in an envelope and write its contents and other important information for identification, especially when the original documents are not available for trial. However, special care should be taken when it comes to electronic evidence.
What is Electronic evidence?
Electronic evidence is an electronic record created on a computer or similar device, made by man, or generated automatically. As such can be used in the evidentiary procedure before a court or other state body decides on the matter. Electronic evidence has the force of a public document and can appear equally in court records. However, it is necessary to get it without modification or damage in obtaining such evidence, with confirmation of authenticity, in the sense of duplication when possible, and performing the analysis without modification. Also, due to its specificity, it must be adequately and marked, where serial numbers are entered for each of them, which are precisely determined. After that, a list is made in the form of a diary or tabular presentation that will contain the given evidence.
