A comprehensive study for discovering and recording the path, reasons, perpetrators, and repercussions of a security event or breach of the organization’s or state laws is known as forensic analysis. In criminal cases, forensic analysis is frequently related to evidence presented to the court. Various analytical methods and techniques are used in finding evidence or the study of documents important to criminal investigations or other legal processes. Biological samples deposited trace materials and residues or contaminated, counterfeit, or hoax materials are all examples of forensic evidence.
Analytical apparatus employed in forensic research has developed to deliver unique information and increasing degrees of detail, bringing up new possibilities in legal investigations.
There are five types of forensic analysis
DNA is a kind of nucleic acid that contains genetic material found in all body parts. This sort of forensic analysis can help solve crimes and establish paternity. A forensic expert isolates the unknown DNA sample, analyzes it, identifies the characteristics and type of DNA, locates a likely DNA source, and compares the test findings to see if the individual’s DNA matches the sample to complete a forensic analysis of DNA.
A computer hard drive forensic examination offers a comprehensive history of the device and its user. This sort of forensic analysis comes in handy when it comes to corporate fraud, intellectual property theft, and threats of violence. Even if a user deletes a file or an email, the information is still stored on the hard drive. Forensic analysis on a computer entails retrieving any documents, emails, spreadsheets, movies and downloads, and any other content for inspection.
Handwriting specialists can identify the author of a document even when the writer tries to hide his writing by using varied stroke directions, pressure regions, and font sizes. Because some people may replicate another person’s writing, most handwriting experts require an original document to establish a comparison and never pronounce two papers as a perfect match. Handwriting analysis may help with behavioral profiling and matching any handwriting found at a crime scene.
- Bloodstains pattern
Bloodstain pattern analysis is a technique for examining bloodstains found at a crime scene. Bloodstains help forensic investigators comprehend the diverse dynamics of altercations and how blood departs the body and comes into touch with a surface. This knowledge enables a forensic investigator to observe blood patterns, quantify blood drops, apply trigonometry to calculate blood drop motion, and piece together a re-creation of a crime scene sequence.
Forensic statement analysis is a way of investigating an individual’s account of events, such as a confession, abduction letter, or terrorist threat. A forensic analyst builds a profile of the author by looking for certain phrases or terms associated with specific social identities or geographic places and assessing the grammar, spelling, and word structure. While this profile will not reveal the author’s identity, it will evaluate the statement’s danger, risk, and deception levels.
Notably, in construction, forensic schedule delay analyses are utilized to resolve construction disputes between two parties. The study and examination of events using CPM scheduling methods to determine the reason and degree of delays and to settle construction delay claims via negotiations or legal actions is known as forensic schedule delay analysis. It is a sector for CPM scheduling specialists who have received training and experience.
