Transaction before that on Oct 8 goes from 1JvBcFjmgPJNRJYP6osMGysjGv7tvSvozD to 19V6cRgL3jHBAppRFKosrTHvZjU3mYg8Dk which goes to 1Ninja afterwards, so 19V6cRgL3jHBAppRFKosrTHvZjU3mYg8Dk is also D.N controlled, which means 188oB1TR6gNXxzyxJCyck9BHkU4dBMVmVg is the return address, but why is the same amount of 30 BTC being sent in this transaction with his own 1JvBc address as the return address? Anyway this tells us that 1JvBc owns 188oB and sends together with 1DMz3S in this transaction to BITDICE.ME COLDWALLET DIRECTLY, confirmed in this post, 1 day before the heist. 
1DMz3 received 10 btc from 1DrJ6L1G72apxrZnmVPSaGmdzi3rLexvqX on Oct 8, a day before the heist, the BTC had been sitting there since June 30th, it was sent to 1Drj6L from 1DwrBhgkxf6Uy8CAtxPiQ9jPAJ61R4VY69, which is a hotwallet of some sort for Just-Dice. 122BNoyhmuUt9G9mdEm3mN4nb73c1UgNKt and 19mh3hMtrhTCkUnvN7o2gi84BGMHEzMM4g are also dooglus controlled wallets.
This transaction shows dooglus Just-Dice wallet sending 126.67 btc to 14dXN2c4R1neEdBAMpbdQSTdrwfCM91cAv, then this transaction happens, the 3 of those addresses have the BTC still sitting there, 1GsGDn then sends the btc to 19V6c D.N in this transaction.
The return address of the last transaction to the bitdice.me coldwallet is 1CSdizJPsna7RAjfY7D5XJn5CjisHuLheU, which sends btc together with 1KohH9iEhnw2XG2y56NPCd6e3QEqN5yzso in this transaction. 1Koh also sends 50 btc to bitdice.me coldwallet directly in this transaction. Both 1 day before the D.N heist.
Also, 19V6 was pretty unactive until 1 day before the heist when 1JvBc sent 27 btc.
Ive been trying to contact Dooglus to ask who 1DrJ6 and 14dXN are but havent been able to talk to him yet, since that person controls addresses that directly deposit to bitdice.me I would get my money out of there, just in case it turns out to be AK/DMF.

You're right that both of those are related to Just-Dice withdrawals.
I wasn't able to follow your logic for why you suspect either of those accounts.
The two withdrawals were from two different accounts. Each of the two accounts always used its own unique IP address, from two different European countries.
Can you explain why you suspect either of them of foul play?
I can verify that this address is in the JD hot wallet:
"address" : "1DwrBhgkxf6Uy8CAtxPiQ9jPAJ61R4VY69",
"ismine" : true,
Edit: also, do you think you could take out the "nl/" from your links? It drives me crazy...
Edit2: I've tried again to follow your analysis. I get lost at "which goes to 1Ninja afterwards". But I wonder if all you have identified is a couple of Just-Dice accounts that withdrew their balances directly to their bitdice.me deposit addresses, and which therefore ended up in that cold wallet.
