Question 12

Imagine a crime scene in which traditional sources of evidence have not yielded a suspect.A DNA profile is generated and run through the CODIS database.There is no perfect match; however,one person has at least one band in common with the crime-scene DNA at every STR site.This person,however,is in jail and could not have committed the crime.Is this information still useful for identifying a potential suspect?
