Assuming this was taken from the BBC, the same article also discusses the latest news that -
"McCanns consider own tests on car
The parents of Madeleine McCann are considering commissioning independent forensic tests on the hire car that they used in Portugal.
A friend of the family says the car is being kept in a "safe place" after it emerged that earlier police tests had uncovered DNA evidence."
Fairly ballsy move that. They have already shown they have no faith in the Portugeezars through openly slagging the sniffer dogs, and police, I suppose it was only a matter of time the forensics where going to feel their wrath.
