I'm surprised Amaral is still receiving and announcing official/unofficial case related updates?
How would the likes of Ney know MM was 'home alone' in an unsecured holiday apartment? Of all the small children sleeping in accommodation over PDL/Algarve on 3rd May he just happened upon one who was without adult supervision in an unsecured apartment. Same goes for the other high profile paedophile Hewlett.
Until I see any firm evidence to the contrary I will continue to believe the abductor was someone who knew the McCanns were wining and dining at tapas every evening and leaving via the unlocked patio door. This narrows the field considerably to those who were able to observe this pattern by way of sound and/or vision.
I don't know where individuals ordered and picked up a takeaway meal from the tapas restaurant. I don't know how much of the tapas dining are might have been visible to them; or if it was possible for them to order a drink at the tapas bar while waiting for the meal to be prepared.
If a predator availed him/herself of a takeaway the coming and going of individuals of child bearing ages might have excited interest ... particularly were a baby monitor in plain sight ... and might have alerted a situation involving children and absent parents.
That intelligence didn't have to be gathered on the 3rd, although it could have been; it could have happened on any of the preceding nights; observation would have quickly ascertained which family was in the most vulnerable situation.
All it would have taken would have been observation following an alert; which may explain the interest shown in Block 5 reported by various witnesses,
