Biological Evidence

Biological evidence refers to samples from living organisms—such as blood, hair, saliva, or tissues—that can be collected and analyzed in forensic investigations. This type of evidence can link a suspect to a crime scene or victim through DNA analysis, which identifies unique genetic patterns. Because biological evidence carries genetic information, it is highly valuable in solving crimes, confirming identities, or establishing connections among suspects, victims, and locations. Proper collection and handling of biological evidence are essential to maintain its integrity and ensure accurate forensic analysis.
