Authorities knew him as the “Dread Pirate Roberts” and the founder of the largest online marketplace for illegal drugs.
His sophisticated site, called Silk Road, made it nearly impossible for authorities to trace him or the users because of an encryption network and digital currency called “bitcoin.”
But FBI agents finally tracked down the alleged founder, 29-year-old Ross William Ulbricht, after he posted his Gmail address online, CNN reports.
Experts were able to track him down at a San Francisco library.
The site allegedly sold drugs, fake IDs, guns and even hitmen.
