Probably a healthy dose of 'parallel construction' going on based on secret evidence. I don't quite understand the dark market, but I assume they basically rely on postal services to transfer most of the drugs. I'm pretty sure, probably starting with the anthrax mailings 20 years ago, that the USPS records images and itineraries for all packages and mail flowing through the system. Combine that with cell phone data and surveillance footage and you have a method of detecting who sent the drugs that the government ordered from the dark web vendors. You also have other possibilities to consider, such as DNA evidence in the packages. I would be very worried if I was committing any sort of major crime these days, unless I had the protection of a government. The tools are all there to catch nearly everyone committing a crime if they are motivated enough.
