So is there any proof of Leonor Cipriano's confession to The Magistrate? I would seriously like to see this if there is any.
There's this in which she apparently did.

From what I can gather, if indeed she had actually done so, it would have been read out to her and she'd have to have formally acknowledged it (or denied it).
Acknowledging it doesn't mean anything in my view as there's no way of knowing what potential carrots and sticks she'd faced during interrogation in terms of intimidation, threats or a prospect of not being prosecuted for murder if she agreed to an accidental death.
I find it perfectly plausible that she could have falsely confessed to an accidental death with a lesser sentence so that Leandro could continue to look after the kids for a few years and try to find Joana. At the time, the PJ didn't even have to present her with the evidence against her... they could just bluff. The alternative was the prospect of a 25-year sentence.
