NEW YORK (AP) — In closing arguments Tuesday, a prosecutor urged jurors to follow the "digital fingerprints" of the San Francisco man who created the underground website Silk Road and to convict him of operating a worldwide online drug network, but a defense lawyer countered that evidence proves his client's innocence.
Assistant U.S. Attorney Serrin Turner told the Manhattan federal court jury that prosecutors in the three-week trial overwhelmingly proved 30-year-old Ross William Ulbricht created the site and operated it for nearly three years, until his 2013 arrest.
"He custom built Silk Road to be an online storefront for drug dealers," Turner said. "He manned the cash register to make sure he got his cut from every sale."
Turner said jurors should look at evidence from Ulbricht's laptop computer, his nightstand, his social media accounts, his trash can and "everywhere else you've seen his digital fingerprints."
Ulbricht's attorney, Joshua Dratel, said his client quit Silk Road soon after creating it to sell anything on the Internet and before the website was overrun by drug dealers.
"Ross Ulbricht is not guilty of each and every count in the indictment," Dratel said of charges carrying a potential penalty of life in prison.
The lawyer told jurors to distrust some evidence because "the Internet is not what it seems." He noted that an investigator — the trial's first witness — established dozens of identities on Silk Road.
"You never know who precisely is on the other side of that computer screen," he said.
The government accused Ulbricht of enabling more than 1 million drug deals on Silk Road and earning about $18 million by connecting dealers with customers they could never find on the street. Serrin said $182 million of the $190 million in sales that could be categorized were for illegal drugs of every imaginable type, even cyanide.
When he thought there was a threat to business, Ulbricht communicated online with someone he thought could carry out murders, Turner said.
The prosecutor noted Turner was not facing murder charges and the government knew of no killings.
"The defendant may have fallen for a big con job," he said. The murder-for-hire plot showed "how far the defendant was willing to go to protect this criminal enterprise," he said.
The trial included numerous online chats conducted by a person whose online alias was Dread Pirate Roberts, a reference to the swashbuckling character in "The Princess Bride." Dratel said evidence proved Ulbricht was not Dread Pirate Roberts.
In a rebuttal, Assistant U.S. Attorney Timothy Howard called Ulbricht's effort to cast himself as the fall guy in a complicated conspiracy "absolutely ridiculous."
"His digital fingerprints are on everything," he said. "He ran Silk Road from beginning to end."
Serrin said Ulbricht was "caught red-handed," logged on to Silk Road under the Dread Pirate Roberts alias when he was arrested in a San Francisco library.
Ulbricht also is charged in Baltimore federal court in an attempted murder-for-hire scheme.
Judge Katherine Forrest said the jury would get the case Wednesday.
