seems they couldn't have found all the working funds, not profit/commission money....the actual funds on deposit user wallets $3.8mil wouldn't cover these outstanding escrow. top ten sellers lost a LOT of BTC, especially one's shipping worldwide. a mega-vendor like supertrips or any international bulk seller who stays in escrow would have had WEEKS worth of orders cycling thru ...
example: even if the average international mail turnover figured as 2 weeks, (bet 20 days closer is to truth) and orders averaged $750. in this example the wallet would hold almost 800K alone and I'd expect any bulk Coke, MDMA, Meth..etc.... vendors all could easily have had 500K in escrow. even domestic.
at the most the funds seized were 1/2 to 1/3 of the operating funds (escrow and balances).
who could guess how many coins DPR had as his own, or where they are deposited. he could have been Private a Financial Backer in BFL and lost it all even after receiving commissions from the sales feeding Josh's rampant Cocaine and dildo addiction... he could have had every satoshi coded then hidden within Yakuza style tattoo's covering his arms, back neck and penis....or maybe "Yakuza style tattoo's covering his arms, back neck and penis" is the passphrase to his brain wallet
