Authorities in New York on Tuesday announced charges against three individuals accused of using the dark web to sell fake Xanax, among other substances, and laundering millions of dollars in cryptocurrency.

Law enforcement started looking into the alleged crime following reported “suspicious activity” taking place at ATMs in New York and New Jersey, Manhattan District Attorney Cyrus R. Vance said in a news release.

The investigation led to the indictment of Chester Anderson, 44, Jarrette Codd, 41, and Ronald Maccarty, 51, in connection to the operation of “storefronts on the dark web that sold and shipped hundreds of thousands of counterfeit Xanax tablets and other controlled substances to buyers in 43 states, and laundering $2.3 million in cryptocurrency by using preloaded debit cards and withdrawing cash at ATMs in Manhattan and New Jersey,” according to the DA’s office.
