This is why Marcos Correia got involved. It's worth reading the whole interview actually, in my opinion the man's barking;
How did that premonition of yours about the Maddie case happen?
On the 5th of May, upon returning from a spiritualist meeting in Madeira, right after going to bed, but before falling asleep, at around midnight, an extraordinary thing happened to me for the first time in my life: I saw the image of a little girl that must have been around 4 years of age, with blonde, shoulder-length straight hair, blue eyes, very disturbed, visibly unable to understand what was happening to her, accompanied by a female being of great beauty and great spiritual standing… Then, other images appeared, related to what had happened to her: I saw a strongly built man, blue eyes, somewhat balding and with blondish hair, brutally raping that girl and then strangling her with his hands, throwing the cadaver into a lake. I perceived by a map that was shown to me, that this happened in the Algarve, but I couldn't read the name of the village. I stress that I hadn't seen any photo of Maddie before, I only knew, from what I'd heard on the radio, that she was 3 years old.
That individual that you describe, was he ever referred to within the PJ's investigation?
In fact, there were references about a strongly built individual of British appearance as a suspect. Still, as this was my first vision in my entire life, there was, on my side, a certain reluctance in divulging it. I let a few days pass, even to see whether or not the little girl showed up. Until I gave the lead to the PJ, on the 9th of May, but they never contacted me. Later on, an agent from the PJ in Portimão told me that the investigation's thesis was not based on abduction anymore. Then, I decided to carry out a private investigation: I went to continental Portugal, and visited the various lakes and dams of the Algarve, until I reached the Arade one which was the only one that precisely matched the scenery that I had seen in my vision. I decided to contact a senior official at Método 3, the detective agency that had been hired by the McCanns to investigate their daughter's disappearance. When I mentioned that the dam was located in Silves, I noticed that they were surprised and immediately wanted to speak with me.
