Right! After his conviction for the diesel theft (november/december 2006?) for a few weeks to a "girlfriend" in Dresden, then to Augsburg (AB?) and then back to Portugal.
So a possible Dresden connection could have been established shortly before MM's disappearance...
"During that period, Christian B. was commuting back and forth between Germany and Portugal. He alternated between living with his former girlfriend in Dresden, Germany, with an acquaintance in Augsburg, in his home in Praia da Luz and then again in a trailer in Hannover and in an allotment garden in Braunschweig. He worked at a car repair shop in Hannover, at a corner store in Braunschweig and lived off of welfare in the times in-between."

I understood this runaround to be after May 2007?
Interesting whether this former girlfriend is named 'B', or maybe it's the girl he first went to Portugal with, this could be one and the same person of course. Or it might be someone entirely different.
