Hi zwiebel,
you posted a link to an online news article,
http://www.morgenweb.de/nachrichten/sudwest/13-jahrige-verzweifelt-gesucht-1.1029280 and even though I put it into translation, I wasn't sure about the text - in German in reads
""Laut der Auskunft einer Freundin hat er Maria-Brigitte auch schon von der Schule abgeholt", so Riske."
in English the translation is:
"According to the information he has a girlfriend Maria Brigitte also been picked up from school," said Riske.
I wasn't sure if the article was saying that he has picked her up from school on occasions before she went missing.
If anyone could translate the German correctly, that would be greatly appreciated.
I also wondered where the photo was from - I thought it was possibly a drivers license photo or a work card photo - something like that.
Yes, at the moment I too am finding it difficult to find specifics such as you mentioned - both for Maria and for Haase. Also background information regarding their disappearance is broadly painted and not very specific. She has been missing 6 days now.
Lets hope there is some breakthrough news soon.
