First off, let me start off by saying that any sizeable bitcoin exchange will cooperate with law enforcement as they are dealing with monetary transactions. You cannot hide your money, and they want to make damn sure of that.
So assuming this pretty much riduclous story is true, I believe he was likely using Evo. It makes perfect sense, connecting the dots. Simply based on the subpoenas we have seen on reddit, we know for a fact that LEA is focusing heavily on Evo and its userbase. Assuming they made some arrest from the internal staff, leaks could have easily occurred and the LEA could be looking into some transactions on Evo.
Luckily I haven't ever touched evolution and will never have the chance now. Either way there is a good chance that this whole situation is related to Evo, as its the most recent market to fall.
Sheep marketplace got away with an exit-scam... until they were all arrested.
So if you were apart of Evo, smash your computer, burn house down, and turn yourself in because you're already screwed. The proof? Well Evo is the only POSSIBLE ENTITY that could have done something bad to that guy, thats what I've determined through heavy research and my B.S major.
you summed up the whole post with the last two words
major bs
