9612 btc was progressively sent over and over at a decreasing rate over thousands of transactions until 7906 was left. Theft and laundering sounds about right.
Edit: Here you go,
it was 10000 btc 1.5 days ago from 376 other addresses: https://www.blocktrail.com/BTC/address/18SwPkgUHFo8QLh5fMcchKvmUVrFNxXF6B/transactions Surely this is Cryptsy-related?

It looks like it was the same 9000 or so coins sent over and over to different addresses. A mixer maybe?

The 5.7 million btc in one block are just 10,000 btc moving and moving. Today, you could spend unconfirmed outputs so you could move the same coins many times in the same block. I think i found the initial transactions :

if you carefully look in blockchain you will see that about 10000 BTCs are branching in large number of small transactions,but in each txs it is always single address - that is common behaviour for paying users by large exchanges.They use option - spend unconfirmed change to broadcast huge number of txs in single block - so in this case it is not laundering - laundering can be spotted as immediate branching of initial transaction on large number of addresses,which also continous to branch in each step after
