Scotland yard were not interested in any of the materials collected for forensic testing after the British dogs visit to Luz and I have never seen any interest being shown by the Brits once they had the test results in their hand.
The Rebello investigation ~ who also had an understanding of the forensic results ~ were disinterested as well as being a little perplexed after viewing the dog video.
They couldn't come to grips with the animal passing the same object on a number of occasions, even playing with it, only to alert to it a little later when it was put in a cupboard.
Scotland Yard were however deeply interested in retesting and testing for the first time, hairs found in the McCann apartment; the Portuguese did not allow them to do that ~ permission was categorically refused.
SnipA Met Police team led by DCI Andy Redwood announced their wish to look again at forensic material collected in the early days of the Madeleine McCann investigation during a visit to the university town of Coimbra earlier this month.
They met with the bosses of Portugal’s Institute of Legal Medicine and Forensic Sciences in Coimbra, two hours drive north of Lisbon, where most of the material, also said to include 25 blood and saliva samples, is held.
Institute president Francisco Brizida, said afterwards: “I have the certainty they went away very happy.”
“The tonic of the meeting was about the possibility of the tests on samples collected in 2007 being re-done.
“The British police wanted clarification on the examinations the institute had carried out during the early stages of the inquiry in the areas of genetics and biology.
“We talked about non-identified material that was collected in Madeleine’s apartment.
“I can’t say for sure new DNA tests that didn’t yield a conclusive result in 2007 could now yield an objective result.
“But technology nowadays allows us to go further than years ago in areas like genetic markers.
“Several possibilities are open. One could be that British police do the tests in Britain with British technology and another that the institute does them.
“But that’s an area in which the institute does not have the last word. There’s a situation of judicial cooperation and a new international letter of request would be necessary.
