Their wallet is
https://blockchain.info/address/15YoDfLcYWpY39C5eHANviTj1CjQ75UH5eThe amount received is 1,993.57651 btc. Not bad.
Apart from a 0.5 btc contribution to MultiBit (indeed a very well done wallet software), the received btc remain untouched to this date.
Maybe the wallet owner is really in big trouble and can't move at the moment...
