Ross Ulbricht, AKA Dread Pirate Roberts, the man accused of being behind the infamous Silk Road online black market, has been charged with ordering an additional four murders on his enemies, according to a report in Forbes. This means that Ulbricht stands accused of a total of six murder-for-hire attempts, though prosecutors do not have any evidence that any of the hits actually took place.

Prosecutors allege that five of the murders-for-hire came about from an attempted blackmail against Ulbricht, although this is actually believed to have been a scam. Ulbricht is said to have been contacted by a Silk Road user, who claimed that he’d publish identifying information about a number of the sites customers, unless he was paid off. But rather than pay off the blackmailer, Ulbricht is said to have instead contacted a hitman on the site, paying him cash to have him and three of his housemates eliminated. However, prosecutors say that the hitman and the blackmailer may well have been the same individual, and that the entire scam was just an elaborate hoax.

In total, feds say that Ulbricht paid $730,000 to have six people whacked. Besides the four blackmailers, Ulbricht is believed to have hired a hitman to murder one of his ex-employees, however in that case the assassin he contacted was actually an undercover agent.

As a result of these fresh allegations, Ulbricht, who is also accused of narcotics trafficking conspiracy, computer hacking conspiracy, and money laundering conspiracy, was once again denied bail at a hearing yesterday:

“Ulbricht should be detained as a danger to the community,” said assistant US attorney Serrin Turner.

“Given his willingness to pay approximately $730,000 for attempts to kill six people, there is no reason to believe that he would not again resort to violence in order to protect himself, whether through intimidating witnesses, recovering proceeds of his criminal activity, or otherwise.”

During the hearing, Ulbricht’s attorney insisted that his client is not a flight rick, offering a total of $1 million as a guarantee that he wouldn’t skip bail. However, a judge in New York once again refused his bail application.

Fresh evidence against Ulbrich was also presented at the hearing yesterday, including a diary that details the origins of the Silk Road, found on his hard drive. In addition, prosecutors claim that Ulbricht was logged into Silk Road at the time of his arrest, showing that he had administrator access to the site under the name of “Dread Pirate Roberts”, who is known to be the site’s pseudonymous owner.
