Gotcha! DNA portrait.

Post by Blind groper » Fri Apr 18, 2014 3:36 am

Reference : New Scientist, 22 March 2014 Page 14


This is just around the corner, possibly next year? A DNA trace left at a crime scene will be used to build a picture of the face of the owner of that DNA. If you are a criminal, better not leave any DNA. And all it needs these days is a sweat print.

This is not yet perfected, and insufficient detail is yet available to build up a distinctive portrait, but it is not far away.

Criminals beware. It will no longer be possible to evade a serious search.

Imagine how easy it would be to leave false dna clues.

Just get a few hairs, or a cup with a finger print, or even a used condom from somebody, and plant it at a crime scene.

The mug wouldn't stand a chance, now that Columbo's dead.

That is the case today, where DNA matching is the ultimate criminal catching tool. How many criminals leave such evidence deliberately?

I didn't word that very well at all.

I meant leave someone else's dna to incriminate them.
It could happen. People are so confident that they've caught the villain, once a dna match is done.

I think BG's point was that perhaps a tiny minority of clever criminals might deliberately muddy the waters in that way, but that some form of DNA analysis, with or without face modelling, will still work very well for the majority...

It sure does.
It's probably the police that have left the majority of the false evidence, anyway, not criminals.
But it could happen.

A cunning criminal might store up all sorts of hair, and other dna samples, and deliberately leave them lying around when he commits a crime. Then, if his own dna is found among it, it would be hard to prove that it wasn't a false clue, left by someone else.
It would cause big problems for the police in court.

It's going to help in identification of suspects in rape cases where the rapist is a stranger. :read:
