More nonsense from sky?

''German investigators want to retest a mystery saliva sample found in the holiday apartment from where Madeleine McCann went missing.
Portuguese forensic tests on the sample apparently found no DNA match to the new suspect, German drifter Christian B.
But the German authorities believe their scientists should carry out their own tests because the sample - thought to have been found on Madeleine's bed - is potentially vital evidence and they hope they can match it to their suspect.
But the Portuguese police (PJ) are unlikely to send the sample, partly because of recent criticism by the German prosecutor Hans Christian Wolters.
He said last week the PJ still believed that Madeleine's parents were responsible for their daughter's disappearance from the apartment in Praia da Luz in 2007. The PJ ruled them out as suspects in 2008.
It is understood the German authorities would apply the same forensic techniques as the Portuguese.
There may also be legal restrictions that would not allow the sample to be sent abroad for retesting in such circumstances.
In 2012, Scotland Yard detectives visited a Portuguese forensic laboratory when they were about to launch their own investigation and their request to retest hairs found in the apartment was turned down.''
Hmm.
I think either Martin has got mixed up or the German authorities have, or a mixture of both.
The only saliva stain on a bed was on the other bed in Madeleine's room and, despite testing "weakly positive" to sperm, was later found to have belonged to the baby boy of a previous occupant... and therefore hardly likely to be sperm.
There is however:
FSS-GF-680 Emissao 2, Pagina 1
On 9 April 2008, the DNA profiles obtained from the probatory components [objects] 286A/2007/CRL1A&B, 4A&B, 9A&B e 16A&B were submitted with a request to the National DNA Database(R).
Various matches were obtained with the results of 286A/2007/CRL4A&B; the majority of them were eliminated based on additional information obtained from the result; however, two remain (namely, bar codes 90264515 & 90374723). Those profiles were obtained using the old SGM system which examined only six areas of DNA. For this reason the samples should be upgraded [re-tested] using the new standard system SGMplus. It is likely that those samples would be eliminated after the upgrade.
Various matches were obtained with the results of 286A/2007/CRL9A&B; the majority of them were eliminated based on additional information obtained from the result; however, one remains (namely, bar code 80004801). It has matched with a sample of a spot recovered from a crime and cannot, at this time, be associated with a specific individual. Nevertheless, as that sample was processed with the old SGM system I consider the match to be of negligible significance.
All matches obtained from other samples were eliminated.
https://www.mccannpjfiles.co.uk/PJ/JOHN_LOWE.htmIf the "national database" meant the UK's one, then the sample would have predated her disappearance by years and therefore irrelevant.
OTOH, if the SGM result had been imported via Interpol for some reason... then there could possibly be a more recent connection. But I find that to be a somewhat remote possibility.
