Curtis Green - the person handling transitions at Silk Road - was arrested in a raid over his house that afternoon, as soon as he accepted the drug parcel. The arrest was done by Carl Force himself - the Baltimore based DEA agent. After the arrest, Force managed to get access to Green’s account on the Silk Road. Green’s arrest was a big surprise for DPR, not because DPR had any knowledge, but simply because of the mishandling of transactions that led him to realise Green was no more a reliable ally.
In parallel, Force played another role - the role of Eladio Guzman (username: Nob). Under this identity, he soon became a trusted friend with DPR. Their relationship began with Nob sending a proposal to buy Silk Road for a billion dollars, which DPR declined. However, they soon became good online friends, with DPR sharing all his personal feelings about Silk Road with Nob and chatting over TorChat every night. When DPR realised Green was arrested, he asked Nob to kill Green (DPR of course had no idea that Nob was the person who had arrested Green). Force (aka. Nob) and Green enact a scene of Green’s death.
The FBI too had its own pack to bring down Silk Road. This group, lead by Chris Tarbell, was researching on every possible way to crack down the marketplace. Tor did challenge them, but after months of failing to hit their target, they stumbled across this post on Reddit that was simply a warning that the IP address of Silk Road was leaking. This begins the fall of Silk Road.
Tarbell had great amounts of knowledge about Tor and its anonymity. If DPR was to be caught, he had to find loopholes in Silk Road itself. The Reddit post gave him a first big lead - he had found the IP address of the world largest illicit marketplace.
Tarbell and team flew to Iceland, the location of Silk Road’s server. They took back a mirror copy of the entire Silk Road marketplace to New York, where they recreated the server through which they got access to the superuser accounts, all of DPR’s chat conversations and practically everything about DPR’s character - except, his name. Tarbell read through all of it, creating an image of the real word person who hid under the username Dread Pirate Roberts.
A big breakthrough soon came. A new agent from IRS, Gary Alford was working on another case pertaining to BitCoins where he discovered a person with the username “Altoid” on a popular forum talking about a new marketplace for everything. With a simple Google search, Gary found this Stack Overflow question asked by a user with the username “Altoid” (who later changed it to the alias “frosty"). On the stack social account, the email address of the person read “email@example.com”. Tarbell knew about frosty as a trusted username on the Silk Road, and if everything was correctly matched, they had found the name of the person behind Silk Road - Ross Ulbricht.
Ross was by now a very frustrated man with all the occurrences at Silk Road. He moved to various localities in the Bay area and finally chose to use his real name and stay in a rented room. He did live a positive social life - very much liked by the people who knew him. He was a “cool” guy to hang out with. Only Ross knew about the pains he was suffering.
Tarbell, knowing he could not track Ross’s online presence due to encryption, chose an odd path - physical surveillance. In the months to come, Ross was physically tracked: whenever Ross used his computer, DPR was online on the Silk Road forum, and when Ross shut the lid of his old Samsung, DPR went offline. This synchronisation was so accurately visible that it was soon obvious that Ross was Dread Pirate Roberts. The game was over.
Tarbell, along with Homeland Security agent Jared Der-Yeghiayan, pulled off a clean arrest on October 1, 2013. The arrest unfolded in a spectacular manner - Ross was sitting at the library when he was distracted purposely and his laptop was pulled away from him, without the lid of the laptop shutting. The laptop need to be on and alive because that was the only real proof that Ross was DPR. That day, Tarbell finally got to walk with the creator of Silk Road - a person he knew in his blood (thanks to all the conversations he had read on the recreated Silk Road server). Silk Road was immediately taken down.
Ross was convicted guilty and is now serving lifetime imprisonment. He still has supporters, for many liked his ideology of a free marketplace. Ross never intended to cause harm but the circumstances he stood in made him act differently. Neither his family nor his friends could believe what they saw. Ross’s caring character was brushed away by his ideologies and knowledge; knowledge that he had not perfected. The loopholes that Ross has led behind during the creation of Silk Road has allowed for his arrest.
Carl Force, in a new twist, has recently been convicted of stealing BitCoins using Green’s computer.
Well, that is it. That was the story of Silk Road.
You must understand the mistakes Ross made. Ross over-trusted Tor. Tor is just a method to be anonymous, but you must realise that Tor is not perfect. Your physical and visual characters can be unique, but they will naturally coincide.
The Silk Road story is a thriller, but it is also a story that ends right. It is your responsibility to use the internet carefully.
