Ross Ulbricht is on trial for allegedly being the mastermind behind illegal drug operation Silk Road.

During a cross-examination of a federal agent Jared Der-Yeghiayan who investigated Silk Road, Ulbricht's defense showed old emails wherein Der-Yeghiayan believed that the Bitcoin CEO was 'Dread Pirate Roberts' which was a pseudonym used by the Silk Road head and a reference to the Rob Reiner film 'The Princess Bride'. He said that he had abundance of evidence that could prove that Mark Karpeles is Dread Pirate Roberts.
