I would love to interview her some day and get to the bottom of this mystery, there are just so many unanswered questions.
She would tell you the same as she told Marcos. IMO
............................that her brother followed Joana after she went out and he returned about 30 minutes later. Joana never returned.
Knowing that his sister was rather backward/slow and forgiving/gentle, I think he might have told her what happened, as in Leonor's 2009 confession and she was initially protecting him.......until he stabbed her in the back that is.
However where in such a short time, could he lose a body?
As in McCann case, there was a lot of building going on and ditches to be filled in the area.
Joao worked in Figueira in construction at times, not that I am saying that he put her in a ditch prepared for filling, just one of my many thoughts on the case.
Was she sold and he didn't want to part with any of the money?
He accused Leandros parents of being involved in the money
He also accused his brother of being involved
and of course he accused, Leonor
In the end it all boils down to evidence and there was nothing with which to safely convict them. Their trial consisted of Propaganda causing a trial by media before it even got to court. The final straw was that video made by Joao and shown in court despite their right to remain silent during the trial.
