It is advisable to consult a legal professional to navigate the complexities of evidence collection and analysis.

Definition & Meaning

Biological traces refer to physical samples collected for investigation purposes, primarily in forensic contexts. These samples can originate from various sources, including crime scenes, deceased individuals, surviving victims, and suspects. Common types of biological traces include bloodstains, saliva (often found on items like cigarette butts or chewing gum), semen, excretions, and tissue samples such as skin, nails, teeth, bone, or hair. Forensic scientists analyze these samples to extract DNA, which can be used for comparative analysis to identify individuals involved in criminal activities.
