How is Forensic Evidence Gathered?

September 28, 2020 3:11 pm


Forensic science is the study of evidence and its sources, such as the physical and biological aspects of a crime scene. A typical crime scene might include blood, hair or saliva, for example. There are also the microscopic features of a crime scene, such as fingerprints, DNA, or fibres. The DNA of an individual can be found in a variety of places, including clothing, saliva, or sweat. This kind of evidence cannot be detected by means of an ordinary eye and must be studied by a trained investigator. DNA evidence is often considered to be stronger than the type of evidence used for fingerprinting and ballistic analysis. Forensic experts will use various methods to collect and review DNA evidence, such as swabs from a crime scene and samples from surrounding areas.

Forensic experts have proven their worth time again, and the scientific community has accepted the validity of their work. Now, the evidence is accepted by law enforcement agencies across the country. Many crimes are often very difficult to prove. The amount of time and resources that would be required in a court of law are almost impossible for an investigator to handle. Therefore, a forensic expert is invaluable to law enforcement. The bagging and storage of such evidence must be strict. For more information on the use of the Security Seal, Find a security seal at

As technology advances, more ways are being discovered to collect and analyse forensic evidence. In fact, more crime scenes now offer a forensic expert with the ability to obtain this type of evidence without a large amount of time spent gathering and reviewing the information. In many cases, these types of experts can provide a more detailed picture of what took place in the crime scene and can give investigators an overall picture of the crime scene.
