a cheap old camper would be much more practical for days off/weekends exploring the algarve - than a jag.The Jaguar came from Germany and had german plates, he most likely arrived in Portugal by car. The van had portuguese plates so, I'm guessing he rented or bought it. He was living at a house at some point so, if he started living in the van, something changed. He was working at hotels and stuff, which is the go to type of job in Algarve anyways and he obviously spoke german and that would make him the perfect candidate to get that type of job. This whole story doesn't make much sense to me. Had a Jaguar but was living on a van, was living at a house at some point for what seemed like a somewhat long period of time but then goes and starts living on a van. I don't really think she was abducted, but I wouldn't be too surprised if a bunch of foreign guys left Algarve in a rush when Madeleine "went missing" and LE started knocking on Robert Murat's door. So, him leaving the country and going back to Germany is not that weird looking at the bigger picture.
Rachel Charles was abducted and killed by Michael Cook, a family friend, in Algarve in 1990. Madeleine is not the first victim, but she would be the first one to be a victim of a stranger.
plenty of people own a camper van for trips, and also rent a house to live in the rest of the time.
