Never know, OP could be the FBI and trolling us.
Unfortunate as it is, DPR didn't secure the wallet well enough, and those BTC are now being used as evidence in the case against him.
If I had been in DPR's shoes, I would've had a sort of "Dead Man's Switch" setup in case of arrest/death. Like a box somewhere that would trigger an upload of the wallet.dat and password, if a private key didn't get entered into that machine every 24 hours, or something. Illicit activities involving millions of USD? Seems silly to not have a Plan B... and Plan C/D/E/F...
Ironically, the only exchange that might consider taking those coins is BTC-E; the only major exchange that doesn't really require dox on clients.
