Here's a sentence from that story:
"DNA has also been taken from the McCanns, their children and 12 other people in their group who travelled from the UK to Portugal."
Originally, the group of travelers, those who dined together that night, were said to be 9 in number: the McCanns, 3 other couples, and the single woman "witness". Were there others in their group who did not dine there that night? Yes, I know that others have traveled to Portugal in the last month in order to be with the McCanns. Has their DNA been taken, or are these five other people part of the orginal group? Maybe the others include nannies, teenagers,...?
If there were other adults among the UK group, that would add another element to this story...one which might connect to the occasionally stated (by LE) belief that the kidnaping had a connection to a UK paedophile ring.
