Sadly, no one seems interested in what really happened to little Joana Cipriano, even though Bruckner had a home around 10 mins drive away. What I haven't been able to find is whether he was actually around there at the time (he was earlier in the year; stopped by road police).
Joana comes from two very respected blood lines
1) The Ciprianos (= from Cyprus)
2) The Guerreros (reputedly her father)
Carana, the following statements were well reported at the time
1) A black limousine was noticed cruising around Joanas home town of Figueira at the relevant period. There must have been something unusual about this for it to be reported. I always thought that it was an elite who probably played at the nearby golf course when he spotted her.
But at that time, I was not aware that Bruckner had such a black limousine. So who lnows ?
2) A man was noticed sleeping in a camper van for a few nights near to Joanas home. This van was reported to have vanished at the time Joana vanished.
The van was found abandoned in a field at Praia de Luz.
Not so many men would chose to sleep on their own in an inland village of the Algarve in a backyard sort of place. Not so many men would abandom their
"home" in a field in a neighbouring village, where Bruckner lived incidently.
As it was abandoned I am inclined to think that it was bought especially for the job of taking Joanna and that she was stolen via motor home possibly for a big fee for a rich man.
The campervan man was not necessarily Bruckner, but interesting possible pointers imo.
I no longer have the energy to search for the cites someone will ask for, but it has already been covered in this forum in some considerable detail and some will remember.
