I don't recall the PJ or Amaral saying "it was the parents" What they were concerned about was the confusion of stories from the tapas group.
It is quite clear that the PJ and Amaral suspected that some kind of accident happened and did wonder if the parents hid the body. The dogs idea was that of the UK police.
The word accident could imply anything; abduction by burglars, Maddie leaving the building to look for her parents and going missing, falling from the sofa banging her head, taking prescription drugs thinking they were sweets... No one in Portugal accused the parents of murdering their daughter.
Team McCann knew the PI's were breaking the law by investigating a criminal investigation. oh yes Technically... Gerry loves that word. Technically it was like sitting in your back garden...hmmm yuhu
