A man's fingerprints are on file in the criminal justice system. Then he commits a second crime, leaving some of his blood at the crime scene.
Can the criminal justice system ascertain from his blood, that he is the same person from the first crime?
You mean, can they track dna to a finger print? What won't they think of next?
Yes, that's the question.
They can only match DNA to a DNA sample. If they don't have his DNA on their database, then no.
This is a great way to detect crime invented by Alec Jeffreys still is a sophisticated way of crime detection
