Carl Force sent 250k or so to BTC-e not too long before his arrest. BTC-e wont work with the us investigators, so a couple things will happen. 1. someone inside btc-e will know the account and take the coins for himself or 2. it will be there for Carls wife or whomever to pull out or 3. hope that BTC-e will still be here in 30 or so years so he can withdraw it if its still there and bitcoin is going strong.
The owners of BTC-e are Russian and they are not going to co-operate with the US authorities. And I don't think that #1 will happen, as Carl Force might not have used his real name and details for the creation of the account. #2 or #3 is quite possible.
