Ulbricht found guilty of all charges in Silk Road case

The prosecution based its case largely on digital evidence

After little over three hours of deliberation, a Manhattan jury found Ross Ulbricht guilty on all counts of conspiracy related to running the notorious Silk Road underground online marketplace.

For his work on the Silk Road website, Ulbricht has been found guilty of narcotics conspiracy, engaging in a continuing criminal enterprise, conspiracy to commit computer hacking and money laundering. The narcotics and criminal enterprise charges carry maximum penalties of life in prison. Ulbricht had pleaded not guilty to all charges. U.S. District Judge Katherine Forrest oversaw the case, which was held at the U.S. District Court of the Southern District of New York, in Manhattan.

Over the course of three weeks, federal prosecutors carefully constructed a case, consisting mostly of digital evidence, that indicated that Ulbricht had maintained Silk Road, which prosecutors estimated had facilitated the sales of more than $213 million worth of drugs and other unlawful goods.

Throughout the trial, the Ulbricht's lawyer, Joshua Dratel, maintained that Ulbricht handed off the site to other operators shortly after he started it in 2011, and that he rejoined immediately prior to his arrest, lured back in by the new operators to serve as a fall guy.

For his closing remarks, Dratel did not offer an alternative explanation for key issues, such as how all the evidence of Silk Road's operations landed on Ulbricht's computer. He didn't need to, he explained to the jury: It was up to prosecutors to show Ulbricht was guilty "beyond a reasonable doubt." Instead he suggested a number of ways that such evidence could be forged, which he argued left enough doubt not to convict Ulbricht.

Nonetheless, the jury found the overwhelming amount of digital evidence to be sufficient to convict Ulbricht.

On October 1, 2013, Ulbricht was arrested in a San Francisco library while he was logged on to Silk Road, under the administrative user name Dread Pirate Roberts. When Ulbricht was arrested, he was using his own laptop, which in the subsequent analysis contained what appeared to be a veritable treasure-trove of digital evidence linking Dread Pirate Roberts to Silk Road and Ulbricht to Dread Pirate Roberts.

Prosecutors also brought a friend of Ulbricht's to the stand, Richard Bates, who described how he helped Ulbricht get Silk Road running in the early days of 2011.

To prove Ulbricht was active with Silk Road through 2012 and 2013 though, prosecutors relied almost entirely on digital evidence. Over the course of three weeks, prosecutors showed multiple instances of where digital evidence found on Silk Road servers overlapped with information found on Ulbricht's laptop and personal online accounts, such as his Gmail account and Facebook account. The laptop also contained thousands of pages of chat logs, in which Dread Pirate Roberts communicated worth other site administrators. The laptop also contained a personal journal that detailed many operations of the site.

Perhaps most damning for Ulbricht were the $18 million worth of bitcoins found on his laptop at the time of his arrest. In its opening statements, the defense had argued that these bitcoins were investment income unrelated to Silk Road. Yet, using the public bitcoin blockchain, which records all transactions, the prosecution was able trace at least $13 million worth of bitcoins being transferred from Silk Road servers directly to the bitcoin wallet on Ulbricht's laptop.

Early on in the trial, Dratel charged that Mark Karpeles, known for being the operator of the failed Mt. Gox bitcoin exchange, may have had a major hand in Silk Road's operations. Karpeles denied any involvement in Silk Road, and Judge Forrest ordered the jury to disregard the claim.

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

Anthony Grifoni


For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

Andrew Mitsi


The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
