Kim Nilsson's group have been investigating the Mt Gox incident for years and he gave a presentation some time ago that summarized some of their findings ( [this video] ). One of the best summaries of the Mt Gox incident, as well as the fallout and subsequent investigations that I've watched.

on HN thread Mark Karpeles Gets Suspended Jail Term
Kim Nilsson's work is as good and unbiased as it comes and it pretty much explains everything you need to know about the missing coins: [this video] [link] Btw, with your 350 coins, I hope you've already submitted a claim and are planning to vote on the upcoming Civil Rehabilitation plan.

It is not unfair to say that the majority of Bitcoin exchanges to date have been either intentionally fraudulant or incompetently run. This includes MtGox. Here's a talk that discusses the financial situation at MtGox and the raging dumpster fire that its security system was when Mark Karpeles bought it. [this video] It's hard to say if the poor security was due to a staggering level of inexperience and thoughtlessness, or if the previous owners had left it open so they could pilfer money as easily as possible before the whole house of cards collapsed. It's hard to imagine a financial services administrator leaving an unsecured Windows file share open to the Internet with all of the private keys on it, but somehow this was considered to be not a problem at MtGox.

on HN thread Mt. Gox demise as told by a Bitcoin insider
There's also this entertaining presentation from an outside researcher (tracing down the missing money) from 3 years ago (I don't know what's up with the framerate, but really, it's worth watching): [this video] It's quite a rollercoaster of failures.
