Dallas, Texas - Wednesday, the U.S. Attorney for the Northern District of Texas announced the indictment of a darknet drug dealer who has been indicted for leveraging Bitcoin’s apparent anonymity to sell fentanyl online.  The charges against him are the result of the first nationwide undercover operation targeting darknet vendors that the Justice Department announced in June 2018.

Sean Shaughnessy, 51, of the Dallas Fort Worth, Texas area, was charged by federal grand jury with conspiracy to possess with intent to distribute controlled substances, distribution of a controlled substance, distribution of a controlled substance analogue and eight counts of money laundering. 

According to the indictment, which was unsealed on May 24 following the defendant’s initial appearance, Mr. Shaughnessy allegedly sold fentanyl and fentanyl analogues over the dark web, an unindexed portion of the internet accessible only via specialized software that allows users to conduct transactions with relative anonymity.  His buyers purchased the fentanyl and fentanyl analogues, which was shipped to their addresses, using cryptocurrencies like Bitcoin, the indictment alleges.  One user, who allegedly purchased a fentanyl analogue from Mr. Shaughnessy, overdosed on the substance and died.  Mr. Shaughnessy allegedly transferred his Bitcoin proceeds to other cryptocurrency wallets in exchange for regular fiat currency, which was shipped to his home in Dallas.  Unbeknownst to Mr. Shaughnessy, he sent more than $120,000 bitcoin to wallet addresses controlled by federal agents. Yesterday, he was ordered to remain in federal custody.  The charges in the indictment are merely allegations, and the defendant is presumed innocent until proven guilty beyond a reasonable doubt in a court of law.

The investigation into Sean Shaughnessy was part of Operation Dark Gold, a year-long, coordinated national operation that used the first nationwide undercover action to target vendors of illicit goods on the darknet.  Special agents of the U.S. Immigration and Customs Enforcement’s Homeland Security Investigations (HSI) New York Field Office posed as a money launderer on darknet market sites, exchanging U.S. currency for virtual currency.  Through this operation, HSI New York was able to identify numerous vendors of illicit goods, leading to the opening of more than 90 active cases around the country, including the investigation into Mr. Shaughnessy in the Northern District of Texas.

The Money Laundering and Asset Recovery Section (MLARS) of the Department of Justice’s Criminal Division, coordinated with law enforcement and federal prosecutors from more than 50 U.S. Attorney’s Offices to investigate 65 targets identified by the undercover operation, which led to the arrest and impending prosecution of more than 30 darknet vendors.

One year after 70 search warrants were executed in May 2018, numerous opioid and narcotics distributors have been charged and convicted around the country. Those include:
