I think that people are going to be wary of using whatever takes over from Alphabay after this news has broke. It is one thing that the site owner got caught because he was stupid enough to use a hotmail address that he also used elsewhere. But to leave all your data exposed on an unencrypted laptop means that the police will be able to start tracing the details of all the transactions that took place on the site and start to arrest the dealers and the buyers.
I am still unsure what to make of this suicide in prison story though, all seems a bit too convenient. I know someone who spent several months in a Thai prison over immigration issues. He tells me that if you have money you can pay off the prison guards and live quite comfortably with your own cell with DVD player, fridge and food brought in for you from the outside and lot of other comforts. If your poor (like most of the Thai prisoners rather than westerners) then your sharing a cell with 30 others lying on a concrete floor with one toilet between you all.
With the amount of money he had i am sure that would have bought him a lot of KFC meals from outside.
