DNA expert in McCann case offer Wednesday, 12 September 2007The inventor of DNA fingerprinting has offered to act as an expert witness in the Madeleine McCann case.
Sir Alec Jeffreys said DNA matches alone did not establish guilt and all Madeleine's genetic characters would be found in at least one family member.
Gerry and Kate McCann, suspects in their daughter's disappearance, are considering commissioning independent tests on a Portuguese hire car.
But the Madeleine's Fund board will not allow money to go on legal expenses.
It has been reported that DNA evidence with a 100% match to Madeleine was found in the car, but this has been played down by Portuguese police.
In an exclusive interview with the BBC's Newsnight programme, Sir Alec said there could be a potential problem in assigning a profile to Madeleine given that all other members of her family would have been in the car.
"DNA testing seeks to establish whether DNA sample A from a crime scene, came or did not come from individual B," he said.
"So if you get a match there's very strong evidence that it did come from B.
"It is then up to investigators, the courts and all the rest of it to work out whether that connection is relevant or not.
"DNA doesn't have the words innocence or guilt in it - that is a legal concept. What it seeks to establish is connections and identifications."http://news.bbc.co.uk/1/hi/uk/6992372.stm
