[78-L] e-bay question ^

[Kristjan Saag]

Knowing that many of you have long experience with e-bay, I ask for advice.
I recently discovered that personal items who had belonged to my late 
aunt, were for sale on e-bay. Identity cards, letters, photos, school 
documents etc. They were labelled "militaria", since most of the 
documents were from the war years.
I happen to know that these things must have been stolen from her 
apartment, which I and my sister emptied after her death. Before this 
there was a long period when social service personnel, cleaners and 
others had access to the apartment; the theft must have occurred during 
this period.
The seller claims he has bought the items on a second hand market. He is 
a trusted seller on e-bay and runs a professional business, both on-line 
and has his own store. There is no reason not to believe his story.
But he is not willing to part from the items in favour of my sister who 
is my late aunts' legal heir - unless my sister  pays him the equivalent 
of 150 dollars for his expenses, that is: the sum he paid when he bought 
the stuff.
The problem is: we didn't know of these items before I found them on 
e-bay the other day. But knowing my aunt, there is no way she would have 
sold her dearest documents (family photos, school-time documents, 
correspondence) herself.
What am I to do next? Report the theft (eight years after my aunt's 
death...)? Or report to e-bay, although the seller has withdrawn the 
items from the list? Any other ideas?
