A months-long investigation into possible money laundering led to a number of arrests, the dismantling of a dark web ring that supplied counterfeit drugs throughout the country and the largest pill seizure in New Jersey history, authorities say.

The probe lead by the Manhattan District Attorney's Office resulted in the arrest of three people in New Jersey in connection to the ring that had about $2.3 million in the sales of counterfeit, albeit potent, Xanax, steroids and other drugs in the past year, prosecutors say. The millions of dollars laundered was allegedly through the use of cryptocurrency.

Chester Anderson, 44, as well as co-conspirators Jarrette Codd, 41, and Ronald MacCarty, 51, were arrested for operating "storefronts" on the dark web that sold and shipped the drugs, prosecutors say.

The three are charged in New York State Supreme Court with conspiracy, as well as money laundering, prosecutors say. Anderson faces an additional charges of criminal sale of a controlled substance and identity theft.

The arrests came after a series of undercover purchases made in cryptocurrency by investigators from the Manhattan District Attorney's Office. This probe led to court-authorized search warrants that were obtained and resulted in the seizure of the largest quantity of pills in New Jersey State history, including about 420,000 to 620,000 alprazolam tablets, as well as about 500 glassines of fentanyl-laced heroin and quantities of methamphetamine, ketamine, gamma hydroxybutyric acid (GHB), and more, according to Manhattan District Attorney Cyrus Vance Jr.

The suspects allegedly laundered more than $2.3 million in proceeds by using the cryptocurrency they received as payment to load pre-paid debit cards, and collectively withdrew more than $1 million from ATMs in Manhattan and New Jersey, according to prosecutors.

Investigators also recovered four pill presses and two industrial mixers, among other drug manufacturing items, and thousands of dollars’ worth of cryptocurrency, prosecutors say.

The probe lasted at least 16 months, according to the source. The three suspects were arrested April 3 in various New Jersey locations with more than 100 officers descending on South Brunswick, Jamesburg and Vineland, among other locations, to make the arrests and confiscate the drugs, a law enforcement source told NBC 4 New York.

The investigation was a joint effort by the district attorney's office, the U.S. Secret Service, the U.S. Postal Inspection Service, and Homeland Security Investigators. 

The owner of a retail store in Asbury Park was among the three arrested, according to the source. The store was allegedly the original money laundering location.

The alleged ringleader was arrested in a South Brunswick home that had a heavy presence of surveillance cameras, the source says. Authorities allegedly found 170,000 Xanax pills at the location of the arrest.

The third arrest took place in Jamesburg, the source says.

The investigation also lead authorities to allegedly find duffle bags with testosterone and Xanax inside in an Old Bridge location.

The three suspects were extradited to New York City.
