Forensic Crime Evidence Recovery
The role of forensic science in criminal investigations is more important today than ever. There are many different types of forensic disciplines that are used to help police and other officials answer these questions. These include criminalistics, forensic psychology, forensic pathology and others. Forensic science is the study of all evidence available to identify a subject. It refers to identifying a victim at a crime scene and an individual that was present at the scene and may be a suspect or material witness. A successful crime investigation depends upon the collection and analysis of various kinds of evidence. Performing a forensic investigation is a long and complicated process. Every inch of a crime scene needs to be processed, starting with collecting finger print evidence from every inch of the crime scene.
A crime scene investigator reconstructs the crime scene, analyzing evidence and carefully documenting each one of their findings. If only one piece of evidence is documented incorrectly, it could put the whole criminal case in jeopardy, potentially setting a criminal free to run the streets. They are trained in what to look for and how to test the evidence. Even the smallest piece of dust or a single hair can yield a wealth of information to a trained investigator. A single hair found at a crime scene can literally tell the investigator if they are looking for a male or female, or if the hair belongs to an animal.
One major distinction is between physical and biological evidence. Physical evidence refers to any item that comes from a nonliving origin, while biological evidence always originates from a living being. The most important kinds of physical evidence are fingerprints, footprints, fibers, paint, and building materials. Biological evidence includes bloodstains and DNA. Trace evidence are items like hair and fibers. Impression evidence is items like foot prints and fingerprints. Along with firearms, tool marks, fingerprints, and footwear, the analysis of tire marks is a key area within the forensic discipline of impression evidence. Tire Tread and Tire Track Evidence presents practical methods for recovering, examining, and interpreting this evidence within the context of actual case studies.
The role of forensics is to provide that level of evidence to investigators who then combine it with other evidence they’ve obtained such as statements from witnesses and victims and possibly a confession from the defendant. Perhaps the most recognized form of forensic investigation is DNA testing. This testing is done by testing physical evidence such as secretions or blood from a crime scene and testing it to determine if it belongs to the victim.
So it is very important to keep the evidence safe used in the criminal activity with the help of some advanced forensic products. As it is required to undergo rigorous quality checks at every stage of production to ensure no contamination is present that might jeopardize potentially vital evidence found at the scene of crime.
A lot of innocent victim gets freedom after investigation proved that they were no way connected with the crime.
