That's not entirely true, the third judge felt there was reasonable doubt as to Leonor's actual involvement, innocent is not a word I would use where the Ciprianos are concerned. They are both guilty to a greater or lesser degree imho.
Joao had reportedly only arrived at Leonor's house on 12th September, the same day she went missing. I find it really hard to believe that Joana's death occurred as described within such a short period of time.
However, perhaps we should pause to give thought to all the lives lost & homes destroyed by the fires which have raged in Portugal again this summer. Some of the scenes shown on ITV news last night were distressing.
While the corrupt politicians siphon illicit gains into their Swiss bank accounts, there are insufficient funds to provide the necessary emergency services the victims need.
Let us hope that the mutterings of fires being deliberately started for corrupt commercial gain are not true.
