> But despite these setbacks, Ulbricht was ultimately convicted in February on a raft of charges, including drug trafficking, computer hacking, money laundering, and hiring assassins to take out members of Silk Road.

Ulbricht's argument to the effect that he wasn't properly charged with the murder-for-hire scheme was addressed in detail by the court:

It seems to me that if the Feds were confident about their murder-for-hire claim, they would have charged Ulbricht accordingly. That they chose not to do so indicates they were less than confident, and we should draw our conclusions accordingly.
For all I know he may well have been involved in murder for hire; I haven't paid close enough attention to the case to have an opinion. But I've followed too many hacker cases to accept unrebutted DOJ allegations as gospel truth.
Capone went away for tax evasion, right?
