As an update to the above interesting to see now ( and as predicted above) they have now accessed the "dead" guys digital wallets only to find them totally EMPTY !! They also state that it seems that he was also using 14 other secret accounts to move money about.
However IF they guy IS actually dead ( and medically proven etc) then that of course leaves the next question as to WHO it was then that emptied out the wallets in the first place as apparently that was completed several weeks and months before his death !
I'm guessing that this is a story that has far to run yet.......and surely is yet another example of why using digital currencies may not be such a smart idea for the holding your life savings ( or any other sort for that matter!) !?
Update to main story from the BBC....
