Who told you the parents are not suspects?!
Do you have a private line to the Portuguese Attorney General or the PJ's National Director?
Last time they talked in public they announced a REOPENING of the previous investigation, which means that the former suspects are still suspects until there's a resolution of the case or a new archiving.
The McCann tried to push into the UK Media the idea that the archiving report exonerated them, but it didn't, it simply stated there was no evidence (sufficient or substantiated) to press charges.
They are not arguido now because they have not been called for interrogation or charged for any crime.

Some people kept insisting that the former arguidos would automatically regain that status once the case was reopened, which doesn't appear to be the case. At least that myth seems to have been cleared up.
The MP reopened the case on the basis of new, credible and pertinent information or leads that the Oporto team presented as a result of their own review. In view of judicial secrecy laws in Portugal, and all the embarrassing leaks to tabloids in the past, I doubt that the general public will have much more information until there is something concrete to announce.
NB: Incidentally, you never did answer my question concerning your post as to whether you could affirm that the person in the room during the Stuart Prior phone call "incident" (if it ever happened) who had told you about this incident understood English or not.
