Physical evidence is any tangible object that can connect an offender to a crime scene.

Using a method called DNA testing, also known as DNA profiling, scientists analyze a long chain of DNA to identify specific “loci.” These loci are very similar when you are comparing the loci of two closely related people, but among people unrelated, the differences are much greater. A DNA expert who examined the laboratory’s records found that the man’s name had been accidentally switched with his cellmate’s name when the profiles were entered into the database, resulting in the false match.
