Isn't this what Perlin thinks he could do.
'YOU WON'T GET AWAY WITH IT' Top forensic expert says Madeleine McCann riddle WILL be solved one day as ‘every contact leaves a trace’

It doesn't appear to be the same at all: Perlin's system is apparently an algorithm that churns out probabilities of a profile belonging to one person as opposed to another unrelated person, when compared to a database. But whose database? A US one? A Portuguese one? A British one?
It can't say that this is Madeleine's x allele, as all of her components would also be in the combined profiles of her parents, and numerous ones would be in common with her siblings and other relatives. It might be useful in some kinds of cases, and may be useful in mass casualty situations for its potential speed in calculating, but I just don't see how it could add anything in this case.
This lady is advocating touch analysis, which is fine, provided that items were handled and stored correctly. Imagine that Christian B had touched something (e.g., a glass) with his bare fingers - that could be useful, but the forensic sweep in 5A didn't go that far.
OTOH, if e.g. her pyjamas had been found and DNA still on them (a bit of a long shot, I would have thought...) that might be a different matter. Or her uncontaminated profile somewhere in one of his vehicles, but again a long shot.
And the Sun, as usual gets totally muddled up:
"And while it has been more than 20 years since Madeleine disappeared on that fateful night in Portugal, Prof Gallop is still optimistic that the answers will be found."No, it hasn't been 20 years.
"As part of the investigation, it is hoped a tiny scrap of blue material held in the vaults of a Portuguese forensic lab could provide the vital link between Christian B and Madeleine.
Tests uncovered a microscopic a DNA profile initially identified as semen, but later confirmed to be saliva.
Scientists were unable to obtain a full DNA profile at the time but have continued to work on it with new testing techniques.
Authorities now hope that continuing advances in DNA testing may yet provide a full profile for comparison with the convicted paedophile and rapist."No, the saliva was identified back in 2007 and a complete profile was obtained. It came from a baby boy.
