Yes, but it says he went to live there after MM disappeared. The German article says the conversation with Dieter F took place in Foral before MM, it could just mean he used to visit there. Perhaps the link with the couple was already established but had not moved in yet.
I'm just trying to piece together where he was supposedly staying between leaving the farmhouse in April and then moving in with the couple running the foster home sometime after MM vanished. Also trying to figure out when he actually went back to Germany. This article implies he didn't go back there until after he left Foral for good but that contradicts what AB said about CB turning up in Germany "shortly after" the abduction and stayed with him for weeks at a time.
It sounds like he was possibly going back and forth. Probably buying weed in Portugal and transporting it to Germany to sell on. AB said he was drying it out on his roof.
