This Cryptsy thing has been fascinating and possibly tragic. Given the rather unbalanced writing in all accounts, I doubt that they are under investigation or are going "full Gox." But I believe the story spooked enough people--myself included--that they withdrew their money as a precaution. Unfortunately, an exchange with no "deposits" is an exchange with no orders, which isn't an exchange at all. The likely-false story has probably led to a massive "run" on the exchange, whose withdrawal mechanisms are overrun by people scrambling for the exit. I think in the end it's likely we will see a solvent exchange, NOT under investigation, which may end up going bankrupt because of a lie.
But that's my take on it. They very well could be doing something wrong--I don't know. I doubt it though. The story is just too fishy.
