Can I pick people's brains please? Brief history:-
My late father had a American penpal since his junior school days. They corresponded for years and years and his penpal, Bob, finally came over for a visit in the 1980's with his wife Laura. My dad died in 1997 and my mum kept up the correspondence with them. However, late last year my mum had her last letter returned marked "gone away" and has been trying to get in touch with the couple ever since. Their phone line is now dead, she has sent a letter to the Oregon police department which has never been replied to, and she has sent letters to neighbours on both sides asking if the couple have moved away. I think she is upset that the relationship has been cut short so abruptly and for no reason - there was obviously much love and shared history between the 2 couples.
Can anybody suggest any other means by which she may find out whether they have moved away or (as I'm sure my mum fears) something very sad has happened (Bob and Laura would be in their mid 80's by now).
Thanks very much for any suggestions...
