To the people saying all this is just a plot to make money - or I also heard Tricia on youtube today wondering if this is another John Mark Karr situation:
This is German LE investigating this, they are not doing this to make money for anyone, they are not a banana republic and do actual investigative work here. It's also not just some guy who confessed and then didn't do it, there was no confession, they found this guy through years of police work. So no, no Karr situation and also no money grabbing plot.
In Germany there is this TV "show" called "Aktenzeichen xy ungelöst" ("Case number xy unsolved"), it's on TV here once a month and yesterday evening it was on as well and that's where they also talked about this case and the new developments and what they are looking for, a German detective was there, etc. They talked about the cars, the phone numbers, basically everything that was mentioned here as well. This is also how the new development made it all over the news worldwide.
This TV show has been around for over 5 decades and was the first of its kind in the world and is similar to "America's Most Wanted", trying to solve crimes, talking to police, having police on the show etc. So it's a respectable source and they don't play around just to get money out of people or anything like that. They seem to have enough evidence to at least investigate this guy further, like I said, it's German LE, they are not playing.
They show cases that could be solved with the help of the public by giving them information and asking for information that they could have, like they asked people who where there on vacation when this happened to send them pictures they took (there is a website to upload them) where you can see cars, or the specific cars in the background, people in the background, etc. So this entire thing is not about money, it's an actual investigation.
So yeah, I trust the information and that they could be on the right track. I myself am and always have been on the fence about what actually happened, I still don't know what to think, that would depend on how much more evidence they have, because of course they don't tell the public everything. But for this to make it to this TV show, there must be quite a lot of evidence.
Aktenzeichen XY... ungelöst
