What is the Locard Principle?

In forensic science, Locard’s principle holds that the perpetrator of a crime will bring something into the crime scene and leave with something from it, and that both can be used as forensic evidence. Dr. Edmond Locard was a pioneer in forensic science who became known as the Sherlock Holmes of Lyon, France. #ForensicSince #forensicGenetics #DNAFingerprinting #BloodAnalyses #STRAnalyses #EdmondLocard #LocardPrinciple
