Biological Evidence: Key Insights into Its Legal Definition and Importance

Definition & Meaning

Biological evidence refers to any type of evidence collected from a crime scene that originates from a living organism. This can include various bodily fluids, such as blood, saliva, and semen, as well as materials like hair, tissue, bones, and teeth. Each type of biological evidence plays a crucial role in forensic investigations, as it can provide significant insights into the events surrounding a crime. The unique characteristics of biological evidence make it valuable for DNA analysis, which can help identify individuals involved in a case.

One common example of biological evidence is blood found at a crime scene. If a suspect's DNA matches the blood sample, it can serve as strong evidence linking them to the crime.
