New York (WRGB) — A New York City man was sentenced to more than 6 years in federal prison after prosecutors said he helped traffic ecstasy through the mail as part of a dark web drug operation.

38-year-old Nan Wu from New York City was sentenced yesterday to 78 months in prison for trafficking methylenedioxymethamphetamine, commonly referred to as MDMA or ecstasy, through the mail. U.S. District Judge Anne M. Nardacci also ordered a three-year term of supervised release to follow Wu’s release from prison.

As detailed in Wu’s plea agreement, prosecutors said Wu worked with a drug trafficking organization that used the dark web and the postal system to traffic MDMA from points outside the United States to New York City for distribution. Authorities said Wu received packages in the mail containing MDMA and delivered the drugs to a co-conspirator in New York City.

The packages entered the United States through the Champlain, New York, Port of Entry and were seized by Homeland Security Investigations. In total, HSI seized more than 10 kilograms of MDMA meant for Wu and his co-conspirators as part of the case.

First Assistant United States Attorney John A. Sarcone III said,

Nan Wu thought he could hide behind the anonymity of the dark web and misuse the U.S. mail to flood our communities with dangerous drugs. He was wrong. Thanks to the vigilance of federal law enforcement, this trafficking scheme was shut down and more than 10 kilograms of MDMA were seized. This case underscores the importance of continuing to marshal the resources, partnerships, and vigilance needed to stop criminals from exploiting the U.S. mail system to traffic dangerous drugs into our communities.

HSI Special Agent in Charge Erin Keegan said,

Nan Wu’s 78 month prison sentence reflects the damage caused by his role funneling ecstasy into New York and fueling addiction and potential crime in our neighborhoods. This investigation disrupted a global supply line, removed more than 10 kilograms of MDMA from circulation, and shielded the community from drugs meant to slip through undetected. HSI Albany and our law enforcement partners are relentless in tracking and dismantling international narcotics schemes that exploit our ports of entry and the postal system.

HSI investigated the case. Assistant U.S. Attorney Douglas Collyer prosecuted it.
