MADELEINE McCann’s case could see a major breakthrough in just one week if crucial DNA samples were re-tested, a leading forensics expert has claimed.
Dr Mark Perlin has offered to re-analyse 18 "inconclusive" DNA samples from the investigation – but Met Police detectives have so far snubbed the suggestion.

He believes new techniques used by his Pittsburgh lab Cybernetics – which identified 9/11 victims – can finally reveal what happened to Maddie.
When asked how long the tests would take, Dr Perlin told the Daily Star: “What we actually need is the electronic data that comes out of the laboratory off their instruments.
“That’s the standard starting point for DNA analysis.
“It would take us one to two weeks, depending on the data, after we receive it to provide some initial preliminary report.”
Madeleine was just three-years-old when she disappeared while on a family holiday in Portugal in May 2007.
CRUCIAL DNA SWABS
DNA samples were taken from swabs lifted from the McCann family's holiday flat and hire car after sniffer dogs allegedly detected the "scent of death".
This crucial swab was from the boot of a silver Renault Scenic that Kate and Gerry McCann leased 25 days after Madeleine vanished in Praia da Luz.
It was one of 18 complex DNA samples, which are potentially loaded with vital clues about Madeleine's disappearance.
Cops reached a dead end when the tests came back inconclusive 12 years ago.
But US expert Dr Perlin reckons new techniques could blow the case wide open.
He previously told Nine's podcast investigation: "If a lab can produce informative data, even if it is complex and mixed, but they can't interpret it then you can have tremendous injustice – of guilty people not being convicted, or innocent people staying in prison.
"What is needed is an objective and accurate interpretation that can scientifically resolve the DNA."
Top British detective Colin Sutton has supported Dr Perlin’s call for further tests, saying it could be a real “game changer”.
