Ulbricht was charged with “narcotics trafficking,” “distribution of narcotics by means of the Internet,” and “conspiracy to traffic fraudulent identification documents” for the first time in a 17-page superseding indictment filed by Attorney Preet Bhararra on Thursday. The indictment also listed Ulbricht’s original four charges—participation in narcotics trafficking conspiracy, continuing criminal enterprise, computer hacking conspiracy, and money laundering conspiracy.
