From the announcement

Drug traffickers who think operating on the darknet will shield them from prosecution should think again. We will scour the darkest recesses of the internet to find those dealing fentanyl, a drug that shatters lives and wrecks futures. We are grateful to the many agents and officers – both in uniform and undercover – that worked together to arrest Mr. Shaughnessy, and to the jurors who thoughtfully weighed the evidence and voted to convict.
Leigha Simonton, U.S. Attorney for the Northern District of Texas, U.S. Department of Justice
This drug dealer, who used the cloak of the dark web to peddle fentanyl and other illicit drugs, is no longer in business thanks to the investigative efforts and technological expertise of our agents and law enforcement partners. Criminals who seek personal gain by trafficking illicit drugs at the expense of victims in our communities cannot hide on the dark web. Our team of special agents and criminal analysts will never relent in our resolve to bring to justice those that seek financial gain by selling this poison in our neighborhoods as we all work tirelessly as a community to address drug addiction and fatal overdoses throughout the country.
Lester R. Hayes Jr., Special Agent in Charge of HSI Dallas, Homeland Security Investigations
