I have no idea why the PJ came to the conclusion that Madeleine had died in the holiday apartment with her parents responsible either to a greater or a lesser degree and then somehow disposed of her a if she was yesterday's rubbish, before they had taken the time to eliminate all other possibilities for which there was real evidence.
Joana Cipriano had vanished without trace from a village in close proximity to Luz and as far as I know no connection to that disappearance with Madeleine's was thought about by the investigators.
Who in my opinion were in a sticky wicket as far as Joana's disappearance was concerned ... the books had been written ... the 'murder' solved ... the mother doing the time ... reputations made as 'crimebusters' too. So it might have been awkward for the same investigators when another little girl vanished in the same area.
Then when Scotland Yard discovered that seven abuse cases of minors had occurred ... later amended to many more ... it blew a gaping hole in any case against anyone until these assaults were ruled out of having any connection either to Joana or Madeleine's cases.
Of course being a murder victim ruled Joana out as a person in her own right ... the PJ had 'proved' she had died at the hands of her mother.
Just as in my opinion Madeleine was set to be ruled another dead non person who had a homicidal maniac for a mother, the ground being primed by pejorative illegally sourced leaks supposedly of her mother's diary.
In my opinion the Portuguese police jumped the gun on deciding Madeleine's death without properly investigating all other avenues ... I doubt there is another law enforcement agency who would have ignored a spate of assaults on minors some of whom may have shared Joana and Madeleine's profile ... when a minor went missing on their watch.
Yet it took the advent of Scotland Yard to take note of this elementary aspect of policing.
British investigate 7 sexual abuse before Maddie disappears
Betting in other cases, in the Luz zone, in 2007. By Miguel Curado | 04.10.17
SnipWhen it appeared to be definitely closed, the investigation into the disappearance of Maddie McCann in 2007 in Praia da Luz, Algarve, revived at the hands of the English Met Metropolitan Police - and with a well-defined course. The investigators focus on seven situations of sexual abuse to minors reported at the time, in that area, and that came to the time deserving the attention of the Portuguese police, namely the GNR, but without any results.
______________________________________________________________________________________
GNR, at the time of its receipt and the six other complaints,
communicated them to the Judiciary Police. It was possible to conclude that at least five situations will have occurred before the disappearance of the child. However, none of the situations came to be used as a line of investigation. Now, ten years later, the Met wants to revive this scenario even because, according to British media reports yesterday, British investigators are in possession of a list of 38 sex offenders who were identified, at the time of the disappearance of the child, in the vicinity of Praia da Luz.
